Open source alternatives to Cursor 3

By GitHub stars it is Paradev, with 16,293 stars and a commit on 14 Nov. Choose Paradev when you want to run coding agents from different makers in parallel worktrees in a free, MIT-licensed desktop app. Next come Orchestrator.inc (14,606 stars) and Dray (131 stars).

Yes. The code of all 3 is public under MIT or Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.

Start from the job you use Cursor 3 for. Choose Orchestrator.inc when you want one board for Claude Code, Codex and Cursor agents that sends failed CI back to the owning agent. Choose Dray when you want many agent sessions in one free, open source app that runs the CLIs you already pay for.

2 of the 3: Orchestrator.inc and Dray. Each tool's page says what it needs to run.

All 3 we track had a commit in the last 30 days, among them Paradev, Orchestrator.inc and Dray. A recent commit shows the project is kept up, not that it will stay that way.

Apache 2.0 (2), MIT (1). MIT, BSD and Apache let you change and reuse the code freely.

The hosting. Cursor 3's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
