DeepSource
Your green light to ship with confidence
Overview
DeepSource takes a two-layer approach to code review: thousands of deterministic static analysis rules for the things that don't need an AI's judgment, and AI agents on top for the fuzzier stuff like logic bugs and anti-patterns. Its PR Report Card breaks feedback down into security, reliability, complexity, hygiene, and coverage, so a team can see at a glance where a change is weak instead of scrolling through a wall of inline comments. Autofix generates patches you can apply directly rather than just describing what's wrong.
The pricing model is worth reading closely before you commit. The Team plan is $24 per user per month, but AI Review itself is metered separately, billed per 10,000 lines of code at $8 for Standard or $15 for Advanced, with a $100 annual credit included per user. That's a reasonable amount for a small team but can climb quickly on a large, active monorepo, so it's worth estimating your PR volume before assuming the sticker price is the full cost.
Key Features
Inline PR Review: Combines 5,000+ deterministic rules with AI agents to catch bugs and anti-patterns.
Autofix: Generates ready-to-apply patches for detected issues without disrupting your workflow.
PR Gates: Blocks merges automatically when code doesn't meet defined quality standards.
Secrets Detection: Validates against 165+ credential providers to catch leaked keys before they ship.
OSS Vulnerability Scanning: Flags dependency vulnerabilities that affect your actual code paths.
Infrastructure-as-Code Review: Scans Terraform and CloudFormation files for misconfigurations.

Pros
Deterministic Plus AI: Static analysis rules catch the obvious stuff reliably, AI handles the nuanced cases.
Broad Security Coverage: Secrets detection, SAST, and IaC scanning are bundled in, not sold as separate add-ons.
Free Tier for Open Source: Unlimited public repos with 1,000 PR reviews a month at no cost.
BYOK on Enterprise: Enterprise customers can use their own Claude, OpenAI, or Gemini keys for AI Review.
Cons
Metered AI Review Costs: AI Review is billed per 10,000 lines of code on top of the base seat price, which makes total cost harder to predict.
Pricing Not Fully Transparent: Enterprise pricing requires a sales call, and the credit system takes some math to estimate real monthly cost.
Setup Overhead: The breadth of features (SAST, IaC, secrets, coverage) means more configuration than a simpler single-purpose reviewer.
What Makes It Unique
Deterministic Rules as a Foundation: Layers AI review on top of over 5,000 fixed static analysis rules instead of relying on AI judgment alone, which gives more consistent baseline coverage than AI-only reviewers.
