Defect-detection audit
Internal audit on 24 pattern-seeded pull requests across three production codebases (TypeScript, Python, Go). Both reviewers ran on Anthropic claude-opus-4-7 with default prompt packs. Severity was labelled before the run; ✓/✕ reflects whether the reviewer flagged the seeded defect on the inline comment.

Feature deep-dives
- 01Pricing// mesrai
Flat per developer, LLM at cost
Mesrai Pro is ₹499 / $6 per developer per month with unlimited reviews, on your own LLM key. INR billing with a GST invoice in India, USD elsewhere. 14-day trial, no card.
// codeant aiPer user, by product line
CodeAnt prices its AI code review, code security, code quality and dev metrics products separately, per user, with the model included. Third-party listings show the AI code review Premium plan at $24 per user per month; check codeant.ai for current figures. A 14-day trial needs no card, and open-source projects get 100% off.
verdict — Mesrai is cheaper per developer for review. CodeAnt can make sense if you want its security and compliance products from the same vendor.
- 02Scope// mesrai
A focused pull request reviewer
Agents for bugs, security, performance and your rules review every pull request with an AST graph of the repository for context, and business logic validation checks the change against its ticket.
// codeant aiReview plus a security suite
CodeAnt combines AI code review with SAST, code quality scanning, AI pentesting and compliance audit reports.
verdict — Want one vendor for review, scanning and compliance evidence? CodeAnt. Want the best-fit reviewer on your own model? Mesrai.
- 03Model choice// mesrai
Bring your own key on every plan
OpenAI, Anthropic, Google, AWS Bedrock, Vertex AI or any OpenAI-compatible endpoint, with a fallback model.
// codeant aiBundled model
CodeAnt's plans include the model; bring-your-own-key isn't part of its standard plans.
verdict — If you need to choose the model or keep code under your own provider agreement, Mesrai is the fit.
