Rectify (formerly Replicate So) vs CodeRabbit

Rectify gives SaaS founders one developer-focused workspace to catch bugs, replay user sessions, monitor uptime, and run support without switching between a dozen tools. The product rebranded from Replicate and now centers on Quanta, an operations agent you steer through conversation rather than dashboards.

Most bug trackers make you configure filters and query builders before you see anything useful. Rectify flips that: you ask Quanta to surface rage-click sessions, draft changelogs from commits, or triage inbox patterns in plain English. The Chrome extension fits teams shipping with Cursor, Lovable, Bolt, Replit, or v0, capturing annotated screenshots, Loom clips, console logs, and network data with each report.

The stack covers monitoring across HTTP, HTTPS, TCP, DNS, and ICMP, on-demand GitHub code scans with file-level findings, roadmaps, changelogs, workflows, and an MCP server that links Claude or Cursor to your scan and feedback data. The site lists 100+ integrations and powers more than 1,000 products.

Pricing uses bring-your-own-key AI: connect OpenAI, Claude, Gemini, Deepseek, or Open Router with zero markup. Paid plans from $29 per month include a 14-day trial with no credit card, and an Idea tier stays free for solo builders.

CodeRabbit comments on pull requests in GitHub and GitLab, summarizing diffs and flagging bugs before a human reviewer opens the PR. It summarizes diffs, flags bugs and style issues, and suggests fixes before a human reviewer opens the PR. Reviews also run in the IDE and CLI, so developers can catch problems before pushing. The product targets engineering teams that want faster review cycles without adding headcount.

Generic AI assistants can comment on code, but they lack repo context and PR workflow hooks. CodeRabbit installs as a GitHub or GitLab app and posts line-level feedback on every pull request, with optional linters, SAST tool output, and linked-repository analysis for cross-repo changes. Pro and Pro Plus tiers add agentic chat inside the PR, docstring generation, autofix suggestions, and custom pre-merge checks that block merges until conditions pass.

Small teams can start on the free tier, which covers PR summarization and IDE/CLI reviews across unlimited public and private repos. Paid plans bill per developer who creates pull requests, not per seat in the org, starting at $24 per user per month on annual billing. Open-source maintainers get free reviews on public repositories with no time limit.
