Watch out: Autonomy means less visibility into what changed — review discipline matters more, not less. Larger organisations may still be routed through sales rather than self-serve.
By QodoTel Aviv, Israel1 product across 1 category
Strong fit. Writes unit tests against existing code and suggests the cases you did not think of, inside the editor.
Free plan
Yes
Free tier for individuals

Pro Team, sold to teams rather than to one person

No yearly price published
Watch out: Generated tests can assert current behaviour rather than correct behaviour, which passes and proves nothing. One plan sold in credit packs rather than a ladder: the price is the pack you pick, it is designed for up to 30 users, and overage is capped at a figure you set.
By MintlifySan Francisco, United States1 product across 1 category
Strong fit. Publishes developer documentation from your repository and drafts the pages from the code itself.
Free plan

Watch out: The AI writing is the smaller half; most of the value is the publishing. There is nothing between the free tier and $450 a month, so the decision is whether five editors is enough rather than which plan to buy.

Built for this. The default, and the one already wired into the editor and the pull request your team uses. A free tier now covers light use.

Watch out: Suggestions are strongest on common patterns and weakest exactly where your codebase is unusual. Pro and above bundle a monthly credit allowance, so premium-model work is metered on top of the seat.
Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for github?
There is no single answer, which is why this page lists 7 rather than one: CodeRabbit, Claude Code, Devin, Cursor, Qodo, Mintlify, GitHub Copilot. 4 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
6 of the 7: CodeRabbit, Devin, Cursor, Qodo, Mintlify, GitHub Copilot. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
