Sourcery Review 2026: Pricing, Features, Pros & Cons
Sourcery's argument is that AI didn't break coding, it broke reviewing — more code, longer queues, and more pressure to wave things through. Here's an honest look at whether its automated review holds up, the 2026 pricing read off the vendor's own page, and the one tier detail that decides the purchase.
Quick Verdict
Best for: Open-source maintainers (free, with real features) and small private teams that want review and security scanning on one bill. The catch is scan cadence — biweekly until you reach the $24 tier, which is the number that should drive the decision.
What Is Sourcery?
Sourcery is an automated code review service that reads every pull request line by line, writes a summary and a diagram of what changed, enforces review rules you define, and runs security scans across your repositories on a cadence set by your plan. It runs in GitHub and GitLab, and also inside the editor via VS Code and PyCharm extensions.
Its framing of the problem is unusually specific, and worth quoting because it is also the honest case for the category: AI produces more code faster, normal peer review can't keep up, PRs pile up, and the pressure to clear that queue is exactly the moment when security gaps, dependency risks and logic errors slip through. Sourcery claims 300,000+ developers on the strength of that pitch.
What separates it from the pure review tools is that security scanning is part of the same subscription, scaled by repository count rather than sold as a second product. That is the genuine differentiator — and, as the pricing section below shows, also where the tier decision actually gets made.
Built an AI code review tool? People land on this review while they are still comparing.
Add it to the coding category — a free listing publishes after review, and it is the same page ChatGPT, Perplexity and Google read when a developer asks which AI reviewer to use. Want it live in minutes with a Verified badge instead? That option is on the form, one-time, no subscription.
Sourcery Pros & Cons
✓ Pros
- •Completely free on public repositories — and not a crippled free tier: the Open Source plan gives you Pro features on public repos, so an open-source maintainer gets line-by-line review and change summaries without ever entering a card
- •Per-seat billing you actually control: Sourcery charges only for the developers you assign seats to, not for everyone in the GitHub organisation. On a 40-person org where 8 people ship code, that is the difference between $288 and $96 a month at the Pro rate
- •Review and security scanning are the same product, not two subscriptions. Most teams currently pay an AI review tool and a separate SAST vendor; Sourcery's Team tier folds daily scans across 200+ repos into the same $24 seat
- •Change summaries and diagrams generated per pull request, so a reviewer can orient on what moved before reading the diff — the part of review that eats the most human attention on a large PR
- •Custom review rules from the Pro tier up, which is what stops an AI reviewer from degenerating into generic style nags. You encode the conventions your team argues about and it enforces those instead
- •Works in the IDE as well as the forge: VS Code and PyCharm extensions alongside GitHub and GitLab, so feedback arrives before the PR exists rather than only after
- •Explicit, checkable data policy: requests pass through third-party model providers (Azure OpenAI, Anthropic, OpenAI) but Sourcery states no code or messages are stored and no provider trains on them — a specific claim you can hold them to, not a vague 'we take security seriously'
- •Bring-your-own-LLM at the Team tier, which matters for shops with an existing model contract or a compliance requirement about which provider sees the code
✗ Cons
- •The free tier's security scanning is nearly decorative: 3 repositories, biweekly. If security scanning is why you are here, the free plan will not tell you whether the product is good — you have to reach Pro (10 repos, still biweekly) or Team (200+, daily) before the cadence is useful
- •Biweekly scanning on both Free and Pro is a real gap. A vulnerability introduced the day after a scan sits undetected for up to fourteen days on the $12 tier, which is hard to defend against tools that scan every push
- •Sourcery's origin as a Python refactoring assistant still shapes expectations, and the IDE story is strongest in Python — VS Code and PyCharm are the named integrations. Polyglot teams should confirm depth in their own stack before standardising
- •No published free trial length or usage allowance on the pricing page — you start a trial and find out, which makes budgeting an evaluation awkward compared with vendors that state limits up front
- •AI review noise is a category-wide problem and Sourcery does not escape it: line-by-line commentary on an AI-generated PR produces volume, and the custom-rules lever that fixes this is a paid feature you have to invest time configuring
- •The security-scan repo counts are the real pricing axis, not seats, and they jump hard — 10 repos to 200+ is the entire gap between Pro and Team. A 25-repo team pays Team prices for every seat to cover repos, not to get reviewer features
- •Enterprise self-hosting is sales-gated with no published price, so regulated teams cannot size the cost without a call — a friction point when the whole appeal is self-serve adoption
- •Rate limits exist on code review and are only stated relatively ('3x' at Team), so the absolute ceiling on Free and Pro is not knowable before you hit it

The Tier Decision Nobody Reads Carefully
Compare the Pro and Team feature lists and the reviewer capabilities look almost the same. Line-by-line review, summaries, diagrams, custom rules — all of that is already in Pro at $12. It is tempting to conclude that Team is an upsell for large orgs and move on.
The thing that actually changes is the security posture. Pro scans 10 repositories, biweekly. Team scans 200+ repositories, daily, with unlimited issue remediation. If you ship to more than ten repos — and most teams with any service split do — Pro's scanning simply does not cover your estate, and you are paying $12 a seat for review plus a scanner that sees a fraction of your code twice a month.
So the honest decision rule is: if you want Sourcery for the reviews and already have a scanner you trust, Pro is the right buy and the scanning is a rounding error. If you want Sourcery as your scanner, price Team from the start — the biweekly cadence at the lower tiers means a vulnerability can sit for two weeks, and no amount of good review commentary compensates for that.

Frequently Asked Questions
How much does Sourcery cost in 2026?
Sourcery publishes four tiers, verified on its own pricing page in September 2026. Open Source is free and gives Pro features on public repositories plus limited security scans across 3 repos run biweekly. Pro is $12 per seat per month and adds private-repo review, change summaries and diagrams, line-by-line reviews, custom review rules, and biweekly scans across 10 repos. Team is $24 per seat per month and adds repo analytics, daily scans across 200+ repos with unlimited issue remediation, 3x review rate limits, and bring-your-own-LLM. Enterprise is sales-priced and adds self-hosting, priority support, a customer success manager and invoice billing. Annual billing saves 20%.
Is Sourcery free for open-source projects?
Yes, and this is the most generous thing about the product. Sourcery is fully free on public repositories, and the free plan is not a trimmed-down variant — it grants Pro features when you work on a project that lives in a public repo, whether you are in your IDE, in GitHub, or in GitLab. The one real restriction is security scanning, which is limited to 3 repositories on a biweekly cadence. For a maintainer, that means you can put automated line-by-line review on every incoming pull request without a budget conversation, which is exactly the adoption path Sourcery wants.
Do I pay for every developer in my organisation?
No. Sourcery states plainly that you are charged only for the developers you assign seats to. You buy a number of seats and assign them to specific people, which means a large GitHub organisation with a small set of active committers pays for the committers, not for the org. This is a meaningful cost difference from tools that price per-contributor-detected, and it is worth modelling before comparing headline seat prices: a $24 Sourcery seat assigned to 8 people can be cheaper in practice than a $12 seat billed across 40.
What is the difference between Sourcery's Pro and Team plans?
Reviewer features are nearly identical; the gap is scanning and scale. Pro at $12 covers private-repo review, summaries, diagrams, line-by-line comments and custom rules, with security scans limited to 10 repositories on a biweekly cadence. Team at $24 keeps all of that and changes the security posture entirely: 200+ repositories, scanned daily, with unlimited issue remediation, plus repo analytics, triple the review rate limits and the ability to bring your own LLM. In other words, if you are choosing between them, the question is not 'do we want better reviews' — it is 'how many repos do we have, and can we live with a fourteen-day scan gap'.
Does Sourcery store or train on my code?
Sourcery's stated position is specific: requests pass through third-party large language model providers — it names Microsoft Azure OpenAI, Anthropic and OpenAI — but no code or messages are stored, and no provider trains on the data. That is a more checkable claim than the usual security boilerplate, because it names the subprocessors. If your organisation cannot send code to a third-party provider at all, the Enterprise tier's self-hosting option is the path, and you should get the data-handling terms in writing during that sales conversation rather than relying on the marketing page.
Is Sourcery still a Python refactoring tool?
That is where it started, and it is no longer the pitch. The product Sourcery sells in 2026 is automated code review and security scanning across GitHub and GitLab, positioned explicitly around AI-driven development — the argument being that AI raises code volume, which lengthens PR queues, which is exactly when security gaps and logic errors slip through. The IDE side survives as VS Code and PyCharm extensions, and the Python heritage still shows in where the integration story is deepest. If you arrived looking for the old refactoring assistant, the review product is what you will find.
Who should not buy Sourcery?
Three cases. Teams whose primary need is continuous security scanning should look hard at the biweekly cadence on Free and Pro — if a fourteen-day detection window is unacceptable, you are buying Team at $24 regardless of how many reviewer features you wanted. Teams with a strongly non-Python stack should confirm IDE depth in their own languages first, since VS Code and PyCharm are the named integrations. And teams that already run a dedicated SAST vendor they trust are paying twice for the scanning half; for them a review-only tool may be the cheaper fit.
