Watchfire vs OpenHands.
OpenHands (formerly OpenDevin) is an open-source autonomous coding agent — a web UI that drives an agent inside a Docker container, with file editing, shell access, and a built-in browser.
The verdict
Pick OpenHands when you want a self-hosted, container-sandboxed, Devin-style autonomous agent with a browser-capable runtime. Pick Watchfire when you'd rather orchestrate the agent CLI you already trust, in a git worktree under a platform sandbox, with a written task contract.
At a glance.
The axes that actually differ between the two tools. The prose below this table is where the nuance lives — don’t pick a tool from a row alone.
| Axis | OpenHands | Watchfire |
|---|---|---|
| Agent backend | OpenHands is itself an agent — its own loop, with bring-your-own LLM (Anthropic, OpenAI, OpenRouter, or any LiteLLM-supported provider). | Pluggable CLI: Claude Code, OpenAI Codex, opencode, Gemini CLI, GitHub Copilot CLI, or Cursor Agent. |
| Isolation | Runs the agent inside a Docker container that mounts your project — strong process-level isolation. | Per-task git worktree on a watchfire/<n> branch. |
| Sandbox | Docker container sandbox; the agent runs as a non-root user inside the container with limited host access. | Seatbelt on macOS, Landlock or Bubblewrap on Linux; sensitive paths blocked by default. |
| Parallelism | One conversation per browser session; multiple sessions are possible but each spawns its own container. | One agent per project, many projects concurrently from a single daemon. |
| Git workflow | Edits files inside the container's mounted workspace; you commit and push yourself, or use the built-in GitHub issue-to-PR flow. | Reviewable branch per task on your machine; auto-merge is opt-in. |
| Autonomy | Designed for high-autonomy runs — the agent plans, runs commands, browses, and iterates. | Interactive by default; autonomous opt-in via Wildfire mode. |
| Local vs cloud | Self-hosted locally via Docker, or use the hosted OpenHands Cloud. | Local — nothing leaves your machine unless you ship it. |
| Multi-project | Per workspace mounted into the container. | First-class — many projects active concurrently. |
| Open source | MIT. | Apache-2.0. |
| Pricing | Self-hosted is free; OpenHands Cloud is metered; in either case you pay your model provider. | No service fee; you pay model API costs of the CLI you pick. |

When to pick OpenHands.
Pick OpenHands when you want a self-hosted, Docker-isolated agent that can do everything a Devin-style cloud agent does — edit files, run commands, browse the web — without sending your code to a vendor. The Docker container runtime is a real isolation boundary, and the browser-capable agent loop opens up tasks pure CLI agents struggle with (filling forms, scraping documentation, debugging through a browser). OpenHands is MIT-licensed, has an active research team behind it, and ships its own UI — useful when you want a Devin shape on your own infrastructure rather than an editor extension or a CLI.
When to pick Watchfire.
Pick Watchfire when you'd rather orchestrate the agent CLI you already trust — Claude Code, Codex, opencode, Gemini, Copilot CLI, or Cursor Agent — than adopt a new agent. Watchfire is intentionally not an agent; it puts your existing agent inside a per-task git worktree and a platform sandbox (Seatbelt on macOS, Landlock or Bubblewrap on Linux), with a written task contract and a reviewable branch per task. There is no Docker daemon to manage, no separate UI to run, and many projects can run concurrently under one daemon with optional autonomy via Wildfire mode.
Can they coexist?
Yes — they solve different problems. OpenHands is well-suited for tasks that need a browser or a full Linux container at runtime (web scraping, GUI debugging, environment exploration). Watchfire is well-suited for tasks that fit inside an agent CLI's normal toolset (file edits, shell commands, tests). A pragmatic split is to use OpenHands for browser- and environment-heavy work and Watchfire for everyday code changes. They do not share state — OpenHands writes inside its container's mounted workspace, Watchfire writes inside .watchfire/worktrees/ on its own branch.
