Prompt, run, edit, and deploy full-stack Node.js applications from a browser tab: Bolt.diy is the official open-source version of Bolt.new's AI coding agent. Its foundation is StackBlitz's WebContainer technology - a sandboxed in-browser Node.js environment where the AI controls the whole stack: filesystem, npm, dev servers, terminal, and browser console. That means the agent does not just generate code; it installs dependencies, runs Vite or Next.js, reads errors, and fixes them. The defining difference from Bolt.new is model choice per prompt: 19+ providers including OpenAI, Anthropic, Gemini, DeepSeek, Groq, Mistral, Amazon Bedrock, and local models via Ollama or LMStudio, extensible through the Vercel AI SDK. Development ergonomics include live preview, a diff view of AI changes, codebase search, file locking to prevent generation conflicts, 15+ starter templates (React, Vue, Next.js, Astro, Svelte, Expo), and MCP support for external tools. Projects integrate with Git and Supabase, and deploy in one click to Vercel, Netlify, or GitHub Pages.

Open Lovable from the Firecrawl team delivers the first truly open-source alternative to Lovable.dev — a chat-driven AI copilot that takes any website URL and regenerates it as a complete, editable React application with TypeScript and Tailwind CSS in seconds. The pipeline combines Firecrawl's intelligent web scraping for JavaScript-rendered pages and single-page applications with your choice of AI provider — Claude, GPT-4, Google Gemini, or Groq — to analyze HTML structure, extract layouts and styling, decompose pages into proper React components, and generate production-ready code following modern best practices. Live preview runs in a secure sandbox environment using Vercel Sandbox with OIDC authentication or E2B Cloud, letting you see results immediately and iterate through natural language chat to request changes like Tailwind migration, componentization, SEO improvements, accessibility fixes, or custom form implementations. The optional Morph LLM fast-apply path accelerates small edits by applying diffs directly without full regeneration. The provider-agnostic architecture means you control costs by routing to different models — use Groq for fast iterations and Claude for complex layouts. Project structure follows Next.js conventions with organized app, components, atoms, styles, utils, and hooks directories. Deploy via pnpm with Node.js 18+ requiring only a Firecrawl API key, one AI provider key, and a sandbox provider configuration. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

With over 84,000 GitHub stars since its April 2026 launch, Open Design has emerged as the definitive open-source alternative to Anthropic's Claude Design. Rather than shipping its own language model, Open Design acts as an agent-agnostic design orchestration layer that auto-detects 25+ coding CLI executables on your PATH — including Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Qwen, GitHub Copilot CLI, Hermes, and Kimi — or connects to any OpenAI-compatible endpoint via its built-in BYOK proxy at /api/proxy/stream. The platform introduces a file-based protocol where SKILL.md files define composable design workflows and DESIGN.md files establish version-controlled brand systems, currently shipping 31 first-party skills and 72 brand-grade design systems. Output spans web and mobile prototypes, live dashboards, presentation decks, raster images, video, and HyperFrames motion graphics, with export pipelines for HTML, PDF, PPTX, MP4, and ZIP. The daemon architecture uses SQLite for project state and serves a sandboxed iframe preview renderer with vendored React and Babel for JSX artifacts. Deployment options include the native desktop app for macOS, Windows, and Linux, local daemon mode via pnpm tools-dev, a single-container Docker Compose path serving both API and Next.js frontend on port 7456, and Vercel deployment for the web layer. On RepoCloud, deploy Open Design on a dedicated VPS with full root SSH access, persistent storage for your design systems and generated artifacts, and complete control over which AI providers and agent CLIs your instance connects to, all under the Apache-2.0 license.

Powering Facebook, Uber, Twitter, and Booking.com, MySQL processes billions of queries daily as the world's most widely deployed open-source relational database. Its default InnoDB storage engine delivers full ACID compliance with row-level locking, crash recovery, and foreign key enforcement, making it the backbone of mission-critical e-commerce, SaaS, and financial applications. MySQL's Document Store bridges relational and NoSQL paradigms, allowing developers to work with schema-less JSON collections alongside traditional SQL tables through the X DevAPI protocol. For high availability, InnoDB Cluster combines Group Replication, MySQL Router, and MySQL Shell into an integrated solution with automatic failover, while InnoDB ClusterSet extends this across data centers for disaster recovery. The database supports multiple storage engines including MyISAM for read-heavy analytics, Memory for temporary high-speed caching, and Archive for compressed historical data. Native JSON functions like JSON_TABLE() transform document data into relational result sets, and spatial data types enable GIS applications. MySQL integrates with every major programming language through official connectors for Python, Java, Node.js, PHP, C++, and .NET, and works seamlessly with frameworks like Django, Laravel, Rails, and Spring. Replication topologies support read replicas for horizontal scaling, and the new Change Stream Applier in MySQL 26.7 enables configurable parallel transaction application with up to 1,024 workers per channel.

T3 Code puts every coding agent you already pay for behind one control surface, so Claude Code, Codex, Cursor, Grok Build, OpenCode, and Antigravity all run on your server while you direct them from your phone, browser, or desktop. Start a thread, choose the provider and model that fit the job, and watch the agent work in a shared conversation instead of a terminal you have to babysit. Permission modes decide when an agent must stop and ask, and its approvals, questions, and plan reviews arrive in the same thread wherever you happen to be connected from. When the work lands, review it file by file in the built-in diff view, then commit, push, and open pull requests through the Git and GitHub integrations without leaving the app. A real terminal sits beside the chat, and projects, settings, and scheduled tasks stay attached to the machine where the code actually runs. Install it as a background service and reach it from anywhere through T3 Connect, a Tailscale or LAN pairing, or the hosted web client, with a pairing code guarding local access. Outside agents can also drive threads over MCP, launching, messaging, and waiting on work across machines you have linked together.

Backed by 44,000 GitHub stars and now part of Figma, Payload is the first headless CMS that installs natively into your Next.js application's /app directory rather than running as a separate service. The code-first architecture uses TypeScript config files to define collections, globals, and field schemas — from which Payload auto-generates database tables with migrations, a fully customizable React admin panel, REST and GraphQL endpoints, and type-safe Node.js local APIs you can call directly in React Server Components. The Lexical-based rich text editor supports block-based layout building, inline media embeds, and nested field structures, while the built-in localization engine handles unlimited locales with field-level translations. Authentication ships out of the box with HTTP-only cookie sessions, CSRF protection, role-based access control definable at the document, field, and operation level, and support for OAuth providers. Version history tracks every document change with full draft and publish workflows, and Live Preview renders content edits in real-time using server components. The job queue system manages background tasks and multi-step workflows deployable via Vercel Cron or standalone workers. Database flexibility spans PostgreSQL, MongoDB, and SQLite through swappable adapters, and the plugin ecosystem includes official modules for SEO, form builders, redirects, nested documents, and search alongside hundreds of community extensions. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

The leading open-source headless CMS with over 72,800 GitHub stars and more than 20 million npm downloads, Strapi has powered content APIs for thousands of organizations since its creation in 2015, providing a complete backend for websites, mobile applications, IoT devices, and any frontend framework through auto-generated REST and GraphQL endpoints. The visual Content-Type Builder lets editors define collections, single types, components, dynamic zones, and relations without code, while Strapi AI introduced in 2026 generates complete content schemas from natural language descriptions, Figma file uploads, or existing JavaScript application code analysis. Version 5 rewrote the platform with a TypeScript-first architecture, replacing the Entity Service with the Document Service API, switching admin panel builds from Webpack to Vite, and integrating internationalization directly into core with unlimited locale support. Database flexibility spans PostgreSQL, MySQL, MariaDB, and SQLite with automatic migration handling. The media library manages uploads to local storage, Amazon S3, or Cloudinary with image optimization and responsive formats. Granular role-based access control defines permissions per content type, field, and locale. The plugin marketplace extends functionality with GraphQL, SEO, email, custom fields, and community contributions, while lifecycle hooks, custom controllers, and middleware enable arbitrary backend logic. Draft and publish workflows, webhooks for external system integration, API token authentication, data import and export, and CRON job scheduling round out a platform that handles content operations from prototype to production.

Describe a component in natural language and watch it render: OpenUI, from Weights & Biases, is an open alternative to Vercel's v0. Type a prompt like "a dark-themed dashboard with a sidebar and charts" and the LLM renders working HTML with Tailwind styling live in the browser. You then iterate conversationally, asking for changes until the design is right, and convert the result to React, Svelte, or Web Components for use in a real project. The backend is Python with LiteLLM routing, so it works with OpenAI, Anthropic, Gemini, Groq, and Mistral API keys, or fully offline against local Ollama models, including vision models like LLaVA that can generate UI from screenshot input - feed a screenshot and the model reproduces or riffs on an existing interface. Generated markup is inspectable at any point, with light and dark mode toggles, theme selection, and responsive previews across device sizes. The practical effect is compressing the mockup-review-revise loop from hours to minutes: a described layout renders in seconds and iterates through follow-up prompts, and because output converts to real framework code, prototypes feed directly into production codebases instead of staying trapped in a design tool. Self-hosting keeps unreleased product interfaces and prompts on your own server, and LiteLLM routing lets you pick the model per task - a cheap fast model for rough drafts, a stronger one for final passes, or free local models for unlimited experimentation.

Unlike pull-request forges, Gerrit reviews every Git change as a series of patchsets, and nothing merges until the required approvals are in. Developers upload with a plain git push to a refs/for ref, adding push options for topics, hashtags, work-in-progress, or private changes. Each change gets a page listing reviewers, CCs, an attention set that flags who must act next, and submit requirements driven by labels such as Code-Review and Verified, with a quick approve button for the last missing vote. Side-by-side diffs with syntax highlighting take inline comments written in Markdown, saved as drafts and published together. A Checks tab shows CI runs reported by plugins, and integrations reach Jenkins, GitHub Actions, Zuul, and webhooks. Access rights attach to groups and branch patterns, including regular expressions, and inherit from parent projects and All-Projects. Sign-in works with LDAP, OAuth, OpenID, or HTTP single sign-on, and SAML through a plugin. A query language filters changes by status, owner, reviewer, label, file path, and reviewer count. Projects pick a submit strategy: merge if necessary, fast forward only, rebase if necessary, rebase always, merge always, or cherry pick. A REST API, SSH commands, and a plugin system extend the server, and an optional Review Agent chat panel can summarize a change once an AI provider plugin is installed.

Backed by over 20,000 GitHub stars, 800 contributors, and organizations like Google, NASA, and the NHS, Wagtail is the Django-powered content management system that gives editors creative freedom through StreamField while keeping developers in full control of data structure and front-end rendering. StreamField lets editors compose pages from a custom library of content blocks — rich text, images, embedded videos, tables, code snippets, and developer-defined custom types — without compromising the underlying data model or breaking responsive layouts. The built-in JSON API supports headless deployments with versioned endpoints for pages, images, and documents, enabling decoupled front-ends in Next.js, Nuxt.js, or any framework that consumes REST. Editorial workflows provide configurable approval chains where content moves through draft, review, and publish states with commenting, task assignment, and email notifications built into the admin interface. Integrated search connects to Elasticsearch for full-text indexing with faceted filtering, or falls back to PostgreSQL and SQLite backends with fuzzy matching support added in v7.4. Multi-site management serves multiple domains from a single Wagtail installation with independent page trees, while the internationalization framework handles content translation with locale-aware URL routing. Image management includes focal point detection, responsive renditions, and automatic format conversion. The platform supports Django 5.2 and 6.0 with Python 3.10 through 3.14 and PostgreSQL, MySQL, MariaDB, or SQLite databases. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD-3-Clause licensed.

Backed by nearly 80,000 GitHub stars and recognized as one of the most popular developer tools in the open-source ecosystem, Hoppscotch delivers a complete API development platform that runs instantly in any browser with zero installation. The platform supports six protocols out of the box including REST with full HTTP method coverage, GraphQL with schema introspection and multi-column documentation, WebSocket for full-duplex communication, Socket.IO, MQTT for IoT messaging, and Server-Sent Events for real-time streaming. Request collections organize your API calls into logical groups with support for sub-folders, environment variables with scope inheritance, pre-request scripts and post-request test scripts written in JavaScript, and automatic code snippet generation in over twenty languages and frameworks. Teams can collaborate in real-time with shared workspaces, role-based access controls, and cloud synchronization across devices. Migration from Postman, Insomnia, or OpenAPI specifications happens with a single click import. The self-hosted edition deploys via Docker Compose with PostgreSQL for data persistence, supporting SSO authentication through SAML and OAuth providers, SMTP configuration with OAuth2, and admin dashboard for user management. The platform also ships as a native desktop application for macOS, Windows, and Linux with offline support, plus a CLI tool for running collections in CI/CD pipelines. A built-in proxy mode bypasses CORS restrictions during development, and an interceptor enables request debugging and response modification.

With over 2,700 GitHub stars, Auto Company is the first open-source framework that runs a fully autonomous AI company 24/7 — 14 specialized agents modeled after Jeff Bezos (CEO strategy), Werner Vogels (CTO architecture), Charlie Munger (critical analysis), DHH (full-stack engineering), Kelsey Hightower (DevOps), Seth Godin (marketing), and eight more domain experts collaborate through dynamic squad formation to ideate products, write code, deploy infrastructure, and execute marketing campaigns without human intervention. The five-layer architecture separates execution, orchestration, cognition, workflow routing, and observability, while the consensus memory pattern uses a single markdown file as a relay baton between cycles — no vector databases, no Redis, no embeddings required. A bash loop invokes Claude Code or OpenAI Codex CLI every 30 seconds, each cycle selecting 2-5 agents from the 14-person pool based on task context. Over 30 reusable skills handle specialized tasks from frontend design to competitive analysis and deployment automation. Circuit breakers trigger cooldown after consecutive errors, rate-limit detection auto-sleeps on API throttling, and sandbox rollback protects against destructive changes. The Python-powered web dashboard displays real-time cycle status, cost tracking per cycle averaging under $2, and agent activity visualization, with CLI control via make start, stop, monitor, pause, and resume. Supports macOS via launchd, Windows via WSL with systemd, and native Linux deployment. The npx create-auto-co command scaffolds a new AI company in seconds. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Try an idea in React, Svelte, Python, or SQL without installing anything: LiveCodes is a browser-based playground where code compiles, runs, and previews the moment you type it. Starter templates open ready-made projects for most of the 90+ supported technologies. The desktop editor brings completion, multi-cursor editing, Emmet, and Vim or Emacs bindings, while a lighter touch-friendly editor takes over on phones and tablets. Packages from npm, deno.land/x, jsr, and GitHub import straight into your code, and a console, compiled-code viewer, and test runner show what happens behind the preview. Bring projects in from GitHub gists, GitLab snippets, JS Bin, or zip files, then share them as links or QR codes, export them as HTML, JSON, or zip archives, or send them to CodePen and JSFiddle. Deploy a project to a public URL on GitHub Pages, sync your work across devices, or broadcast your editor and result live to a classroom. An embed builder and SDKs for JavaScript, React, Vue, Svelte, Solid, Preact, and web components place playgrounds inside documentation pages, and prefilled code makes every example editable. Projects stay private by default. Local assets, snippets, themes, and dark or light modes tailor the workspace to each person.

With over 14,000 GitHub stars and enterprise adoption by security-conscious organizations, Coder transforms how development teams provision, manage, and secure their coding environments. Every workspace is defined as a Terraform template, meaning infrastructure engineers can standardize development environments across EC2 instances, Kubernetes pods, Docker containers, or any combination, while developers get self-service provisioning that launches in seconds rather than days of manual setup. The WireGuard-based networking layer establishes encrypted tunnels between developer machines and remote workspaces, providing low-latency access without exposing ports or configuring VPN concentrators. Automatic idle detection shuts down unused workspaces after configurable periods, directly reducing cloud compute costs for organizations running hundreds of developer environments. The Coder Agents feature introduces native AI coding capabilities where the agent loop executes entirely within the control plane on self-hosted infrastructure, keeping LLM API credentials out of individual workspaces and eliminating credential exfiltration risks. Centralized model governance allows platform teams to approve specific AI providers and models, set per-user spend limits, and maintain complete audit logs of all prompts, tool calls, and agent activity. IDE integration supports VS Code through a dedicated extension, JetBrains IDEs via Gateway and Toolbox plugins, and browser-based code-server for web access. The template registry provides pre-built configurations for common development stacks. DevContainer support builds environments from standard devcontainer.json specifications.

Content types, media libraries, workflows, roles, search, and a GraphQL API all ship in the box with Orchard Core, a free CMS and application framework that hosts many separate websites from one install. Editors build content types in the admin by combining parts and fields, with no migrations to write, and preview an item live before publishing it. Designers adjust page HTML safely with Liquid templates, and developers add their own modules. Multi-tenancy runs many isolated sites from one deployment, each with its own content, users, settings, and theme, and a setup screen lets you pick a recipe and database for each site. Media uploads can be resized on the fly and stored on remote providers, and a visual workflow editor automates content approvals, webhooks, and form submissions. A typed GraphQL API feeds headless sites and single-page applications, and custom SQL or Lucene queries can be exposed as endpoints. Roles and fine-grained permissions decide who can do what, OpenID Connect handles external sign-in, and two-factor authentication protects accounts. Content and the admin interface can be localized, and deployment plans move content and configuration from staging to production. SQLite works out of the box, SQL Server, MySQL, MariaDB, or PostgreSQL can be chosen at setup, and the official Docker image starts a site with one command. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD-3-Clause licensed.

Stormkit delivers a self-hostable PaaS that eliminates vendor lock-in while providing Vercel-class deployment workflows. The Go backend handles build orchestration, hosting, and background job processing while the React frontend provides a complete management dashboard for applications, environments, and team collaboration. Git integration with GitHub, GitLab, and Bitbucket enables push-to-deploy workflows where every commit triggers automated builds with preview links posted directly to pull requests. Serverless functions use filesystem-based routing — each TypeScript or Node.js file in the API directory becomes an endpoint automatically, deploying to AWS Lambda with configurable timeouts. PostgreSQL database schemas ship with automatic migrations, isolated credentials per environment, and secure environment variable injection preventing credential leakage between staging and production. Custom domains provision TLS certificates automatically through Let's Encrypt with support for custom certificates and headers. The environment system creates isolated deployment contexts for production, staging, and development with independent variables, domain bindings, and auto-publish rules per branch. Privacy-respecting server-side analytics track visitors, referrers, and top paths without client cookies or third-party scripts. Role-based access control manages team permissions across applications. Docker Compose deployment provisions the full stack including the API server, hosting service, build runner, and worker server.
