With over 6,500 GitHub stars, HolaOS bills itself as an "open agent computer" that reimagines the traditional operating system as a shared workspace where humans and AI agents collaborate across files, browsers, and 100+ integrated tools simultaneously. Unlike chat-only interfaces, HolaOS places live application UIs—Notion-style editors, browsers, custom workspace apps—side by side with the agent conversation, so operators always see what agents are doing and can intervene at any moment. The persistent memory system stores workspace knowledge locally as Markdown files and embedded vectors via SQLite vec, enabling RAG-powered recall that survives session boundaries without the typical context window bloat. Safe Session Compaction reserves roughly 70% of the model context window for fresh reasoning while folding older history into structured checkpoints that retain goals, constraints, progress, and decisions. Agents connect to Linear, GitHub, Slack, Jira, HubSpot, Gmail, and dozens more through one-click OAuth, automatically fetching relevant signals and converting scattered app data into working memory. BYOK support for Claude, GPT, and Gemini models lets operators use their own API keys at zero markup, while built-in Kimi K3 and GLM-5.2 models provide ready-to-use alternatives. Skills package reusable workflows that any agent can invoke on demand, and scheduled triggers enable autonomous digests, monitors, and reports. The runtime supports independent server deployment alongside the desktop client.

With over 7,700 GitHub stars and thousands of Cloudflare employees using it daily across every function, Cloudflare OS delivers an open-source AI workspace where every employee gets a personal agent grounded in company context, systems, and skills — not a generic chatbot but a programmable workspace that builds real applications, automates workflows, and connects to internal tools through governed access. The Code Mode agent writes and immediately executes code snippets to perform arbitrary tasks, build full-stack Gadgets with client code, server code, APIs, and durable SQLite state, debug errors, and test results within isolated sandboxes. Gadgets are private application instances running in separate sandboxes — each document, spreadsheet, or tool is its own secure runtime that cannot leak data even to attackers with access to other Gadgets. Blueprints enable sharing application code as templates that others instantiate with independent state, credentials, and resources. Gatekeepers provide security governance giving system owners precise control over what agents can see, change, and when human approval is required before actions execute. Built on Cloudflare Workers using Durable Objects for workspace persistence, Dynamic Workers for Gadget execution, and Facets for access management. Zero Trust security via Cloudflare Access verifies every user and request before granting access. Real-time collaboration lets colleagues use shared Gadgets. Deploy to your own Cloudflare account or self-host on workerd, the open-source Workers runtime, on your own servers. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

GrowChief delivers a self-hostable social media automation engine that replaces expensive SaaS tools like PhantomBuster, Expandi, and Zopto with a Docker-deployable alternative you fully control. The React and NestJS monorepo architecture runs headful Chrome via xvfb with Playwright and Patchright for maximum stealth — natural mouse movements and randomized interaction patterns make automation indistinguishable from manual browsing. Temporal orchestration manages workflow execution with built-in concurrency control that throttles actions to one every ten minutes per account even when ten workflows trigger simultaneously, preventing rate-limiting and account flags. The enrichment waterfall resolves profile URLs from partial data — provide an email address or organization name and GrowChief queries multiple providers to locate the correct social profile automatically. Working hours scheduling ensures outreach runs only during configurable business hours regardless of when leads enter the pipeline via the public REST API. Proxy support accepts custom SOCKS5 and HTTP proxies per account for geographic distribution and IP isolation. The public API enables full workflow management and lead injection from n8n, Make, Zapier, or any HTTP client, with a dedicated n8n custom node shipping ready to install. The multi-step workflow builder lets you chain connection requests, profile visits, message sends, and conditional delays into repeatable sequences.

Huginn has established itself as the definitive open-source automation engine for developers who refuse to hand their workflow data to third-party cloud services. The platform lets you build agents that scrape websites, monitor RSS feeds, track weather via APIs, watch Twitter streams, aggregate news, detect price changes, and trigger notifications through email, SMS via Twilio, Slack webhooks, or social media posts to Twitter and Tumblr. Each agent creates and consumes JSON events, propagating them along a directed graph where complex multi-step workflows emerge from simple single-purpose components. The web interface provides visual agent management with drag-and-drop scenario building, real-time event logs, scheduling controls, and a built-in agent library covering dozens of use cases out of the box. Huginn supports Liquid templating for dynamic event transformation, regex-based content extraction, JavaScript-based data manipulation, and HumanTaskAgent for crowd-sourced workflow steps. Custom agents can be packaged as Ruby gems and loaded via the ADDITIONAL_GEMS environment variable without modifying core code. Deployment options include Docker with the official huginn/huginn all-in-one image or huginn/huginn-single-process for production multi-container setups with PostgreSQL or MySQL backends, plus native support for Heroku and OpenShift PaaS platforms.

OpenRun replaces the patchwork of CI/CD pipelines, reverse proxies, and identity providers that teams typically assemble when deploying internal tools, offering declarative GitOps-based deployment of web applications to Docker, Podman, or Kubernetes from a single self-hosted Go binary. Point it at a Git repository and it builds containers from AppSpec templates, routes requests by domain or URL path, provisions TLS certificates automatically, and scales idle applications to zero when unused. Blue-green staged deployments promote new versions through development, staging, and production environments with atomic rollback across multiple apps simultaneously. Every deployed application inherits SSO authentication through OAuth, OpenID Connect, or SAML providers alongside role-based access control, all configured once at the platform level rather than per app. Service bindings provision isolated PostgreSQL, MySQL, SQLite, or Redis credentials for each application, while Litestream integration replicates SQLite databases to S3 for automatic disaster recovery. The management console provides a web interface for monitoring containers, reviewing audit logs, configuring syncs, and managing server operations. AppSpec templates handle Streamlit, Gradio, FastAPI, Flask, and FastHTML projects out of the box, deploying existing Python applications without requiring custom Dockerfiles.
