DeepSource vs Secretlint

DeepSource is an AI code review platform for teams writing code with AI. It reviews pull requests through static analysis and an AI review agent, looking for bugs, anti-patterns, and security vulnerabilities. The review process uses more than 5,000 deterministic rules, while Autofix can provide verified, pre-generated patches for many detected issues. Other checks include secrets detection, open-source dependency vulnerability scanning, and infrastructure-as-code review for Terraform and CloudFormation. Teams can track code coverage and set thresholds for tested code. Supported version-control systems include GitHub, GitLab, Bitbucket, and Azure DevOps; listed integrations also include Jira, Okta, OneLogin, Slack, and Vanta. The service is available through web, API, Linux, macOS, Windows, and self-hosted deployment. Its GraphQL API has a documented limit of 5,000 requests per hour per user. The Open Source tier costs nothing and includes unlimited public repositories and members, plus monthly limits for reviews and formatting runs. Team costs $24 a year, billed yearly, with a stated rate of $24 per user per month. A 14-day trial is available. Enterprise uses custom pricing and offers cloud or self-hosted deployment, among other listed features.

Secretlint is a free, MIT-licensed, open-source linting tool for finding credentials in projects and helping prevent commits that contain them. Its command-line interface scans files, glob patterns, or standard input. Detection rules are separate modules, and custom rules can be distributed as npm packages. Secret values are masked in lint error messages by default, reducing exposure in terminal output and logs. Secretlint supports Git workflows, including pre-commit integrations with Husky and lint-staged, pre-commit, and Git hooks. Documentation covers GitHub Actions checks and pull-request annotations through the GitHub formatter. Listed integrations also include Mega-Linter, SARIF formatting, a browser extension, and a macOS clipboard app. The WebExtension works with Chrome and Firefox DevTools to help notice credentials in requests and responses. Installation options include Node.js, Docker, or a single executable without Node.js; the Node.js route requires version 22 or later. It detects secrets but does not automatically fix them.
