What you get on free
Online code review without a credit card
The free tier is designed for individuals and small trials - same review quality as paid plans, with usage limits that keep the service fair for everyone. Exact quotas and feature gates live on Pricing.
Security and correctness
Findings call out risky patterns and logic bugs with short explanations - not a dump of generic warnings you will ignore after the third alert.
Fast feedback
Paste a snippet or connect GitHub - get structured feedback you can act on in one sitting, before the context of the change evaporates.
Plain language
Suggestions read like a careful reviewer - useful for learning, for solo maintainers, and for teams that want a shared quality bar.
Try before you pay
No card required to open an account and run real reviews. When you need higher limits or GitHub breadth, you upgrade on your schedule.
Same engine as paid
Free tier is a volume cap, not a toy model - you get representative output so your evaluation matches what paid seats will see.

Why offer a free tier
Evaluate quality before you standardize
We keep a free tier because the best way to judge an AI code reviewer is to run it on your own snippets and repos. You should see how issues are grouped, how explanations read, and whether the signal matches how your team ships - not read a marketing bullet list.
When you are ready for automation, GitHub and the API meet you where your pipeline already runs - without throwing away what you learned in the browser.
Free is not a demo with fake models - it is the same review path with guardrails on usage. That way when you pitch CodeCritic internally, your proof matches what finance will pay for.
Growing past solo use? Read AI code review for teams for billing, shared workspaces, and governance - and the online tool page if you want a browser-first story for new hires.
How free code review fits your workflow
- Web: paste or upload code for a one-off review when you do not want to wire CI yet.
- GitHub: connect a repository and run reviews where your team already works.
- API and automation: available on paid plans - see Features for the full surface area.
