Why teams move from Nimbalyst to Fredrin
The ticket is the unit, not the session
Nimbalyst's kanban organises agent sessions. Fredrin's organises tickets: a ticket owns a branch, a worktree, a plan with acceptance checks, and a pull request, and it isn't done until that PR merges. The board tracks shippable work rather than conversations.
Isolation without opting in
In Nimbalyst a session can opt into its own git worktree. In Fredrin every ticket gets one automatically, because running a whole board in parallel only works if no two agents can touch the same files by accident.
Review is the finish line
Fredrin is built around the glance: a ticket lands in review with its diff, its PR and its real CI status on the card, and merging closes it. The surface is optimised for deciding whether to ship, not only for building.
An honest read
Choose Nimbalyst
You want visual editors — markdown, mockups, diagrams, data models — beside your agents, real-time multiplayer on those documents, a phone app, or a Linux build. Nimbalyst is MIT-licensed, free for individuals with no feature limits, and does all of that; Fredrin does none of it.
Choose Fredrin
You want each task to arrive as a reviewed pull request with CI status on the card, an isolated worktree per ticket by default, and a paid Team plan — and you're on macOS or Windows.
Nimbalyst vs Fredrin: FAQ
- Is Fredrin a Nimbalyst alternative?
- Yes, and it's the closest comparison on this site — both are desktop apps with a kanban for running several coding agents in parallel. The split is what a card represents. A Nimbalyst card is a session, surrounded by visual editors for markdown, mockups and diagrams. A Fredrin card is a ticket with a branch, an isolated worktree, a pull request and CI status, and merging that PR completes it.
- Nimbalyst is open source and free — why pay for Fredrin?
- Fair question, and Nimbalyst genuinely wins on licence and price: it's MIT, free for individuals with no feature limits, and runs on Linux, which Fredrin doesn't. Fredrin charges for the shipping half — PR and CI status flowing back to the board, a review-optimised diff surface, and a Team plan that puts several people on one board.
- Does Fredrin have the visual editors Nimbalyst has?
- No. Nimbalyst ships markdown, mockup, diagram and data-model editors with real-time multiplayer, and Fredrin has no equivalent. Fredrin's Project Context lives as plain files in your repository, which agents read directly from the worktree.
- Which agents and platforms does Nimbalyst support?
- Nimbalyst runs Claude Code, Codex and OpenCode, with MIT-licensed desktop builds for macOS (Apple Silicon and Intel), Windows and Linux, plus a mobile companion for iOS and Android. Fredrin runs Claude Code, Codex, Cursor and Copilot on macOS and Windows, with no Linux build and no mobile app (both as of July 2026).
