Use Case Recommendations
Best for: DeepSource
DeepSource is a code review platform that combines deterministic static analysis with AI review agents, which is a more defensible design than either half alone. Pure LLM reviewers hallucinate issues and miss the boring ones; pure static analysis buries teams in false positives. DeepSource runs over 5,000 deterministic rules alongside an AI review agent and reports inline on every pull request across security, quality, complexity and coverage, with Autofix generating the patch rather than just describing the problem. The surrounding platform covers SAST, infrastructure-as-code scanning, secrets detection, code coverage, OWASP Top 10 and CWE/SANS Top 25 reporting, open-source dependency vulnerability scanning with license compliance, and automated code formatting on every PR. Monorepo support is explicit, as are API and webhook access, Slack and Jira integrations. The reason this matters more now than it did five years ago is stated plainly on the homepage: teams are writing more code with AI, and the review bottleneck moved. A DeepSource MCP server ships, so the analysis is readable by a coding agent as it works rather than only at PR time. Public repositories are free with 1,000 reviews and 1,000 formatting runs a month. Enterprise adds self-hosted deployment and bring-your-own-key AI review, where inference runs on your own Anthropic, OpenAI or Google credentials inside your infrastructure.
Ideal use cases:
- •Teams or individuals who need hybrid static analysis plus ai review agent on every pr
- •Teams or individuals who need autofix generates the patch, not just the finding
- •Teams or individuals who need sast, iac scanning, secrets detection and code coverage
- •Teams or individuals who need oss dependency scanning with license compliance
- •Anyone focused on code-review workflows
- •Anyone focused on static-analysis workflows
Best for: Sourcery
Sourcery is an automated code review service built for the situation where AI writes most of the code and human review becomes the bottleneck. Its diagnosis is specific: AI raises output volume, which lengthens the pull-request queue, and the pressure to clear that queue is exactly when security gaps, dependency risks and logic errors slip through. So it reviews line by line on every pull request, produces summaries and diagrams of what changed so a reviewer can orient before reading the diff, and enforces custom review rules you define. Alongside review it runs security scanning, with the scan cadence and repository coverage escalating by tier — limited scans across three repositories biweekly on the free plan, ten repositories on Pro, and 200-plus repositories scanned daily with unlimited issue remediation on Team. It works in the IDE (VS Code, PyCharm) as well as in GitHub and GitLab, and Team adds repository analytics, triple the review rate limits and bring-your-own-LLM. Sourcery is completely free on public repositories, which makes it easy for an open-source maintainer to adopt before paying anything. On code handling the company is explicit: requests pass through third-party model providers but no code or messages are stored, and no provider trains on the data.
Ideal use cases:
- •Teams or individuals who need line-by-line automated pull-request review
- •Teams or individuals who need summaries and diagrams of code changes for faster orientation
- •Teams or individuals who need security scanning with per-tier repository coverage and cadence
- •Teams or individuals who need custom review rules
- •Anyone focused on code-review workflows
- •Anyone focused on security-scanning workflows
