fusion

Open-source 'software factory' (the vendor's own term) where planning, execution and review agents work on tasks in separate git worktrees, per the README and site. The README says the dashboard has kanban, list and graph views; the vendor also lists a fn CLI, desktop shell and mobile clients. Labelled early preview.

Official site

fusion review

Fusion describes itself as an open-source "software factory" where AI agents plan, build and review coding tasks, each in its own git worktree. The site says it is built on pi, and the README says it builds on dustinbyrne/kb, which GitHub calls a kanban-style pi extension. We read the vendor's site, README, docs and GitHub pages in November 2026. We did not install or run it.

How a task moves

The README says a planning agent turns a task into a PROMPT.md plan with acceptance criteria. The site says each step is planned, reviewed, executed and reviewed again, then squash-merged. The README says merging is automatic by default. You work from a browser dashboard, which the README says has kanban, list and graph views, or from the `fn` CLI. The docs also cover scheduled routines, plugin authoring and MCP server settings. The README lists Anthropic, OpenAI and Ollama among its model providers. For other boards that run agents in worktrees, see Cline Kanban and Vibe Kanban.

Cost and releases

The LICENSE file is MIT. We found no pricing page, and /pricing returns a 404. The site and README mention no paid plan. GitHub showed 1,324 stars on 12 November 2026. The latest stable release is v0.77.0 from 2 September, and v0.78.0-beta.9 is a prerelease from 23 October. The site says shipping daily; the README badge says weekly.

Facts: platforms, price and licence

platforms
macOSWindowsLinuxWebAndroidWindows: desktop installers (win-x64 exe and portable exe) are attached to v0.77.0 and to the v0.78.0-beta.9 prerelease. macOS and Linux: the README and site document Homebrew, a curl install script and npm for the fn/fusion CLI and dashboard; v0.77.0 has Linux and Windows fn-cli binaries but no darwin binary. macOS .dmg desktop builds last appeared in release v0.77.0-beta.2 (2026-08-18) and Linux .deb/.AppImage in v0.76.0-beta.0 (2026-08-08); neither the current stable nor the beta carries them, although the site still lists macOS (Intel + Apple Silicon) and Linux (deb, rpm, AppImage). Web: dashboard served by the fn dashboard daemon. Android: a file named fusion-android.apk is attached to releases; RELEASING.md describes that name as the unsigned debug fallback and says Android is sideload-first before 1.0 with Play Store upload out of scope. iOS: the README and site claim native iOS/iPadOS apps, but no IPA, TestFlight or App Store link was found (the site's App Store and Play Store tiles carry no links; MOBILE.md only describes building in Xcode), so ios is not listed.
price
FreeNo pricing page found (runfusion.ai/pricing returned 404 on 2026-11-12) and no paid plan mentioned on the site or README; the software is MIT licensed (seen 2026-11-12). Cost of model use was not examined; the README lists providers (Anthropic, OpenAI, Ollama and others) that can be connected.

fusion features

✓ documented · – absent or not in its feature list · ? not verified

fusion strengths

  • MIT licence; no paid plan or pricing page found; the README lists model providers to connect (Anthropic, OpenAI, Ollama and others)
  • Per the README, each task gets its own branch and worktree (fusion/{task-id}); the site describes plan, review, execute, review, then a squash merge that the README says is automatic by default with manual approval optional
  • Documented fn CLI, scheduled automations and routines under /api, a plugin authoring guide, and MCP server definitions managed with fn mcp (all as documented, not tested)
  • Docs describe a dashboard reachable from other machines through a tunnel, and the README and site mention a PWA for phones; Windows installers and an Android APK are attached to releases

fusion weak points

  • README badge and site header both say early preview; the v0.77.0 release notes list several breaking removals, including task splitting
  • Current stable (v0.77.0) and the v0.78.0-beta.9 prerelease attach Windows installers and an Android APK only; the last macOS and Linux desktop builds in the releases date from August betas and earlier releases, while the site still lists both platforms
  • The site shows App Store and Play Store tiles without links and no iOS build was found; the Android file name matches the unsigned debug fallback described in RELEASING.md
  • The README labels Hermes, Paperclip and OpenClaw runtime plugins and multi-agent Chat Rooms experimental (the site calls some of these plugins first-class); the docs say Node.js 22.19.0 or later is required

Who fusion is for

best for
Developers comfortable with an early-preview project who want a free, self-hosted board that, per the vendor, runs planning and review agents across git worktrees.
look elsewhere if
Anyone who needs a terminal emulator or an SSH/SFTP client, a signed macOS or Linux desktop installer, or a store-distributed iOS app.
