## 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, or an installed phone app. Nimbalyst is MIT-licensed, free for individuals with no feature limits, and does all of that; Fredrin has none of the editors or the multiplayer, and reaches your phone through the browser rather than an app you install.

### 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. Both run on macOS, Windows and Linux, so the platform no longer decides this one.

## 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, so why pay for Fredrin?

Fair question, and Nimbalyst genuinely wins on licence and price: it's MIT and free for individuals with no feature limits. 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 and Codex, with more agents on the way, and now ships for all three of the same desktop platforms; its mobile support is the full product running in a phone browser rather than an installed companion app (Nimbalyst's figures as of July 2026).
