Online code review toolinstant AI feedback
CodeCritic runs in your browser: sign up, start a review, and see security and correctness findings with suggested next steps. It is the fastest way to judge whether our signal fits your team - before you invest in GitHub-wide rollout or API automation.
When to use the web tool
From quick checks to a full workflow
Use the online tool when you want feedback before you commit to CI wiring, when you are comparing vendors, or when a teammate drops a snippet in chat and you want a second opinion fast. Limits by tier are on Pricing.
Fast in the browser
Paste a snippet or upload a file and get structured findings in one sitting - no local install, no Docker dance before your first result.
25+ languages
Broad language coverage with detection in the product - helpful when you jump between services written in different stacks.
Plain-language fixes
Issues are grouped with severity and short explanations - closer to a careful reviewer than a wall of rule IDs.
Seconds, not hours
Feedback arrives quickly enough to fit between meetings - so you can iterate before context goes cold.
Same engine as GitHub & API
When you graduate from paste-only flows, you do not switch products - you add integrations on top of the same review core.

Why a browser-first tool
Evaluate quality before you change your pipeline
Buying team-wide code review is easier when developers have already seen the output. The web tool gives you representative results without asking DevOps for secrets or CI time on day one. That matters for startups choosing between vendors and for enterprises running a cautious pilot.
The experience is intentionally straightforward: one place to paste, one place to read, one place to share a link internally. When you are convinced, graduate to GitHub so every PR benefits from the same bar.
This is also where individuals learn the product - interns, contractors, and maintainers who do not own the org's CI yet. They still get value from structured feedback while leads decide on team-wide rollout.
If you are comparing spend, pair this page with free tier specifics and the plan matrix on Pricing so expectations stay realistic.
