Open source alternative to Cursor
Cursor is the most popular AI editor and its inline editing is still the best in the category. The searches for an alternative usually come down to three things: the source is closed, the bill is per seat and grows with the team, and the editor keeps no durable record of what the agent did or why.
Closed source. Built on a fork of VS Code, which is itself MIT, but the fork is not published.
macOS, Windows, Linux.
Subscription per seat, with usage limits on the faster models.
Why people replace Cursor
Closed source, and the code goes to their servers
Requests are proxied through Cursor infrastructure. For regulated work, or an air-gapped network, that is the end of the conversation.
The per-seat bill scales with the team
Every engineer needs a seat, and usage limits sit on top of the seat price.
No memory of why
The chat that produced a change is not attached to the commit. Six months later the code is there and the reasoning is gone.
One editor, one agent
If you also run Claude Code in a terminal, the two do not share a history, a plan, or a view of what changed.
The layer above your agents
Apache 2.0, running on your machine
The whole stack is public. The engine indexes locally; no code has to leave the machine unless you turn on team sync and point it at your own server.
Every agent, one record
Cursor can stay your editor. Aura sits above whichever agents you run and keeps one history across all of them.
The reasoning attached to the commit
Each change carries the session, the goal and the stated intent. Trace any line back to the conversation that produced it.
A diff you can read at speed
Aura reads changes as logic, not text: a rename stays a rename instead of a thousand-line rewrite, under a header that says what changed and why.
Aura is not better at everything
- Cursor tab completion and inline edit are better than anything Aura has, because Aura does not compete there.
- If you want one thing that both writes and reviews, Cursor is one download and Aura is two.
- Cursor works on Windows today. Aura ships macOS and Linux, with Windows in beta.
The other open-source options
If Aura is the wrong shape for what you need from Cursor, these are the projects worth reading first.
Cline
The closest open-source thing to the Cursor agent, inside VS Code, Apache 2.0.
Continue
Apache 2.0 autocomplete and chat for VS Code and JetBrains, including local models.
Zed
A fast native editor with agent support, licensed GPL, written by the Atom team.
Aider
Apache 2.0 pair programmer in the terminal that commits its own work.
How the move actually goes
- 01Keep Cursor. This is not a swap; most people run both.
- 02Open the same repository in Aura and let it index. The index is local.
- 03Give the next task a goal sentence, then let Cursor or any other agent do the work.
- 04Read the semantic diff in Aura before you commit, and check the verdict.
- 05If you want to drop the Cursor subscription later, Cline or Continue with your own API key covers the editing side.
Aura and Cursor
Can I use Aura and Cursor together?
Yes, and that is the common setup. Cursor writes, Aura reads, proves and records. They share the repository and get on fine.
Does Aura send my code anywhere?
Not by default. Indexing and semantic analysis run locally. Team sync is opt-in and can point at a server you host.
Is there a free tier?
The app and CLI are free and open source. You bring your own agent subscription or API key.
Does it work with the models I already pay for?
Yes. Aura drives the agent CLIs you have installed and uses their credentials.
