With over 78,000 GitHub stars, 270 contributors, and seven years of continuous development tracking upstream VS Code releases within days, code-server has become the definitive way to run a full Visual Studio Code IDE on any remote machine and access it from any browser on any device. The project applies a curated set of patches to Microsoft's VS Code codebase that add password authentication, sub-path hosting behind reverse proxies, self-contained web views that never call out to Microsoft servers, a built-in proxy for accessing ports on the remote machine directly through the VS Code ports panel, and on-disk settings persistence instead of browser storage. The extension ecosystem works with the Open VSX marketplace by default, giving access to thousands of extensions for Python, JavaScript, Go, Rust, Java, and every other language, along with themes, linters, formatters, and debuggers. The integrated terminal provides direct shell access to the server, Git integration handles version control without leaving the editor, and the debugger supports breakpoints, variable inspection, and step-through execution for Node.js, Python, Go, and other runtimes. DevContainer support enables reproducible development environments defined in JSON configuration files. Installation options include a one-line install script, manual package installation, Docker via the official codercom/code-server image, and DevContainer features. Minimum requirements are a Linux machine with 1GB RAM, 2 vCPUs, and WebSocket support.

Eclipse Che spins up complete development environments on Kubernetes from a Devfile in the project repository, so new developers click a factory link and open a browser IDE with dependencies, runtimes, and debugging already configured instead of spending their first day installing toolchains. Each workspace runs as a DevWorkspace custom resource in the user's namespace, making environments API-manageable with kubectl and GitOps tooling alike. Developers choose their editor per workspace, from Visual Studio Code Open Source to JetBrains IDEs via Projector, and the 7.124 release adds Orca, an agent development environment for working alongside AI coding agents. Workspaces carry their own containers for build and run, so code executes in a production-like environment with direct Kubernetes API access from the IDE. Teams standardize stacks as Devfile templates, onboard contributors in minutes, and open a fresh workspace per branch or pull request in a new browser tab. The 7.124 release also builds workspace lifecycle commands into chectl, including SSH connections with port forwarding to desktop editors, and DevWorkspace Operator 1.0 adds optional per-workspace NetworkPolicy isolation.

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.

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.

Open a browser tab, sign in, and the whole RStudio workbench is waiting there, running against R on a Linux server instead of your laptop. The familiar four-pane layout holds a source editor, an R console, Environment and History tabs, and Files, Plots, Packages, Help, and Viewer tabs. The editor opens R scripts, R Markdown, Quarto, and Python files, with code completion, diagnostics, section outlines, and a visual mode for Quarto documents. A Terminal tab and a Python console sit beside the R console, and the Data Viewer sorts, filters, and searches data frames and nested lists. Editor breakpoints and tracebacks help debug functions, while Background Jobs run long scripts in separate R sessions so the IDE stays usable. Shiny apps and Plumber APIs run as background jobs with live reload, and a Git pane handles diffs, commits, pushes, and branches. The Connections tab browses databases, and finished reports go to Posit Connect, shinyapps.io, Quarto Pub, or RPubs. Optional Posit Assistant adds an AI chat pane that works with the model provider you choose, and administrators can switch it off. Because everything runs server-side, a class, a lab, or a team can share one large-memory machine and keep computation next to the data without installing anything locally.

Pi Pocket puts the Pi coding agent in your phone browser, so you can start, steer, and review real coding sessions from anywhere while the work stays on your own server. Open a folder, a fresh Git worktree, or a GitHub repository, pick a model per session, and watch streamed replies with tool calls, queued follow ups, and a stop button when a run wanders. Sessions survive crashes and restarts because every model call, tool call, and subagent step is stored as it happens, and forks let you retry any reply with a different model on another branch. Invite teammates into a live session with presence, roles, and a side chat the agent never sees, or let PiP, the built in assistant, follow your other sessions and report back. GitHub watches and webhooks wake the agent when pull requests, issues, or workflows change, while scheduled messages and cron style goals keep routine work moving overnight. Spend views show cost per person and per session, and owner set limits pause new work instead of quietly burning budget. On a phone you get push notifications, dictation, share sheet intake, and a home screen app, and live reloadable extensions add routes, modules, and commands without a build step.

WebCodex gives ChatGPT, Claude, and other MCP clients a real development environment on machines you own, so an AI assistant can edit your actual repositories instead of a pasted snapshot. A self-hosted Server authenticates every request and routes it to a Runner sitting next to your code, where file edits, Git operations, test runs, shell commands, and long jobs execute with your real toolchain. Your projects never move into a hosted workspace; only the tool results you authorize travel back to the model. The browser Runtime Console shows project readiness, the work queue, session activity, and connected Runners, and it is where you decide pending approvals or accept and reject finished work, because the model cannot approve its own changes. Runners join with a short-lived pairing code and stay connected over QUIC, WebSocket, or polling, so machines behind NAT still work. One-command sharing opens a temporary session for a single repository, while durable setups run the Server and Runner as system services behind your own HTTPS domain. Workflow Sessions keep evidence and context across conversations, so long tasks survive closed browser tabs and threads you pick up days later.

SCM-Manager puts Git, Mercurial, and Subversion repositories behind one web interface, so modern projects and legacy archives live on the same server under the same accounts and permissions. Create or import repositories into namespaces, then browse code, commits, branches, tags, and diffs in the browser instead of cloning just to look around. Central user and group management applies fine-grained permissions per namespace and repository, so contractors see the one project they joined and nothing else. Everything in the interface can also be driven through a Level 3 REST API, which makes bulk repository creation, permission audits, and migration scripts ordinary HTTP calls. Plugins installed from the built-in plugin center add pull-request style code review, build status from your CI, links into issue trackers, and extra authentication providers. Configuration happens entirely in the web interface, with no config files to edit and no separate database or web server to install first. Old Subversion and Mercurial repositories keep working beside new Git projects, which ends the usual two-server split during a long migration. The embedded account system works on its own, and authentication plugins take over when accounts already live in another directory your organization runs.

Browse, upload, edit, preview, and archive the files on your server from any web browser, with no FTP client, no shell session, and no database to set up. Tiny File Manager lists every folder in a sortable table showing size, modified date, permissions, and owner, with a search box that filters as you type. Drag files into the upload zone, send several at once, or paste a URL for the server to fetch. Rename items, select several to copy, move, delete, or pack into a zip or tar archive, and extract uploaded archives on the server. Click any text file to open the built-in editor, which offers syntax highlighting for 150+ languages and 35+ color themes, so quick fixes to configs and scripts happen where the files live. Images, audio, video, and text open in a preview without downloading, and every file has a copyable direct link. Give teammates or clients their own accounts, each locked to a root folder you choose, mark accounts read-only, and limit uploads to approved file extensions. Hide folders you never want listed, restrict access with IP allow and block lists, switch between light and dark themes, pick from 35+ interface languages, and use the responsive layout on a phone. Setup is one file copied to a web server, or one Docker container. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Judge0 is a code execution service that takes source code over a simple HTTP API, compiles and runs it inside a locked-down sandbox, and hands back exactly what the program printed, how long it took, and how much memory it used. Send a snippet in any of more than 90 languages, from Python, JavaScript, Rust, and Go to C, Java, and Haskell, and pick the compiler or interpreter variant you need. Each run accepts standard input, command-line arguments, and custom compiler flags, then reports standard output, errors, and a precise verdict covering accepted, wrong answer, time limit, compilation error, or runtime failure. Per-submission controls cap CPU time, memory, stack size, and output file size, so a fork bomb or an infinite loop dies inside its fence instead of disturbing the host. Submissions run one at a time or in batches, and a synchronous mode answers in the same request for snippets that finish fast. Webhooks call your application the moment a long job completes, which keeps polling loops out of worker queues and classrooms alike. Coding platforms grade student work with it, hiring tools run candidate solutions against hidden tests, and AI agents execute the code they generate before trusting it. Official Python and JavaScript SDKs wrap the raw requests, so most integrations shrink to choosing a language and reading the result fields.

GitArena gives your team its own place to host code, combining repository hosting, issue tracking, and code review in one lightweight service you run yourself. Push and pull over HTTP or SSH, browse code in the browser with syntax highlighting, blame, and raw views, and follow commit history with diffs branch by branch. Repositories can be forked, archived, tagged, and released with downloadable assets, and every project gets an issue tracker with labels, milestones, assignees, and a kanban board. Issues are stored natively in Git using the git-bug format, so they travel with the repository and remain readable offline with the git-bug CLI. Merge requests collect changes for review before they land, while organizations and teams control who can see and change each project. Search spans code, repositories, issues, and users from one box, profiles show contribution graphs and activity, and sign-in supports passwords, SSH keys, passkeys, and OAuth single sign-on. A REST API exposes the platform to your own tooling, and the whole service runs from a single Docker Compose stack or a compiled binary with a separate frontend build.

Your team's code lives on someone else's server, under someone else's terms, until you decide it should not. CodeFever is a fully open-source, self-hosted Git hosting service that gives a small team unlimited repositories, branches and tags, merge requests, and branch protection on hardware as modest as one CPU core and a gigabyte of memory. Developers browse code with highlighted version comparisons, review changes through merge requests, and organize work with repository groups, member roles, and per-member permissions. Protected branches keep important history safe and make review the normal path to main, and webhooks connect pushes and merges to the other systems your team already runs. A super-admin backend manages every project and user on the instance, and the interface speaks Chinese and English natively. Installation is a single Docker command, updates preserve your data, and there are no repository counts, seat limits, or paid tiers waiting downstream. It suits a studio keeping client work private, a lab sharing models and notebooks, or a company that wants its source behind its own firewall.
