Comparison

Vettd vs Sourcery
which one fits your workflow?

Sourcery is one of the older AI code-review players, originally a Python refactoring tool that expanded to general code review. Pricing is per-seat with strong free tier coverage for open-source repos. Strongest in Python and PyCharm; supports VS Code, GitHub, GitLab. Like Greptile and CodeRabbit, it does not audit the deployed website.

TL;DR

Pick Sourcery if

  • Your stack is primarily Python — Sourcery has the deepest Python coverage of any AI code reviewer.
  • Your team already lives in PyCharm — Sourcery has a mature PyCharm plugin.
  • You're an open-source maintainer — Sourcery Pro is free for up to 3 OSS repos.
  • You want self-hosting on day one (Sourcery Enterprise offers it).
  • Per-seat pricing aligned with your team size is acceptable ($12-24/seat/mo).

Pick Vettd if

  • Your stack is TypeScript / Next.js / React — Vettd is built specifically for the JS ecosystem.
  • You want to audit the live deployed site, not just the source.
  • You're a small team or solo dev — per-project pricing wins over per-seat for low-headcount teams watching multiple apps.
  • You want AEO checks (llms.txt, citable schema, FAQPage) — Sourcery doesn't cover this.
  • You want auto-fixes shipped as Markdown for AI agents (Claude Code / Cursor / Windsurf).

Who picks which

A recommendation for your situation.

Python data team / ML org
Heavy Python codebase, mix of notebooks and production services, PyCharm-first.
Pick Sourcery

Sourcery's Python depth is unmatched among AI code reviewers — they grew up in this ecosystem. PyCharm integration is mature. Vettd's code-side rules are TypeScript / React / Next.js focused, with limited Python coverage today. Pick Sourcery for Python-heavy teams.

TypeScript / Next.js team shipping AI-built apps
Modern web stack, Vercel/Railway deploy, PRs from AI tools (Cursor, Claude Code, Lovable).
Pick Vettd

Vettd was built for this exact stack. Specialized rules for App Router migration gotchas, Server vs Client Component pitfalls, NEXT_PUBLIC secret leaks, "use client" misuse, hardcoded Stripe / GitHub / OpenAI keys. Plus the live-site audit on top. Sourcery does general-purpose code review across many languages; Vettd goes deeper in the JS lane and adds the deployed-site layer.

Open-source maintainer of a public repo
Solo maintainer or small contributor base, public GitHub repo with regular PRs from outside contributors.
Pick Sourcery

Sourcery Pro is free for up to 3 open-source repos with biweekly security scans. Vettd doesn't have a free tier for code review — Watch starts at $19/mo. For pure OSS work where you're not also auditing a deployed site, Sourcery is the right cost choice.

Migration & interop

How to move, or how to run both.

Switching from Sourcery to Vettd

If your stack is JS-heavy and you're paying per-seat for Sourcery, consider whether per-project pricing fits better. A 5-person team paying Sourcery Team is $120/mo; if those 5 people are watching 5 projects, Vettd Watch 5 is $49/mo and adds the live-site audit. The reverse is also true: a 1-person team watching 5 projects is $24/mo on Sourcery (one seat) vs $49/mo on Vettd. Run the math against your team-to-project ratio.

Running Sourcery and Vettd side by side

Some teams use Sourcery for the depth of code review (especially Python-heavy orgs) and Vettd for the live-site audit + AEO + completeness layers. Both install as independent GitHub Apps. Expect overlap on basic security and code-quality findings.

FAQ

Answers to the obvious follow-up questions.

Does Vettd review Python code?+

Limited — Vettd's code-side rule library is TypeScript / JavaScript / Next.js / React focused. We use the upstream ESLint ruleset and our own AST rules tuned for the JS ecosystem. For deep Python review, Sourcery is the better choice.

I'm a solo OSS maintainer. Why not just use Sourcery free?+

For pure code-review work on OSS repos, Sourcery free is genuinely the right tool — it's their differentiator and we don't match it. Vettd starts being more interesting if you also need live-site auditing for the project's docs site, marketing landing, or hosted demo.

Per-seat vs per-project pricing — when does each win?+

Per-seat (Sourcery): wins when you have many devs working on few repos (a 5-person team on 1-3 repos pays $60-120/mo). Per-project (Vettd): wins when you have few devs across many repos (a solo dev with 5-10 projects pays $49-99/mo). The crossover is roughly when devs ≈ projects.

Does Sourcery do live-site auditing?+

No. Sourcery is code-review only. Vettd's Site Scan is a separate surface that audits the deployed website — security headers, Web Vitals, legal pages, AI search readiness, etc. — none of which a code reviewer covers.

BYO LLM — can I bring my own Anthropic / OpenAI key?+

Sourcery Team and up offers this. Vettd doesn't today; we run all LLM inference through our backend (Straico-powered) and pass the cost through in the subscription price.

Self-hosting?+

Sourcery offers it on Enterprise. Vettd doesn't. If self-hosting is a hard requirement, Sourcery is the right pick.
