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: Plannotator
Plannotator is a locally-run review surface for AI coding agents, addressing the two moments where agent work usually goes wrong: approving a plan you skimmed, and merging a diff you never really read. On the plan side it hooks into the agent's plan step automatically where hooks are supported, and offers slash commands where they are not. Instead of squinting at terminal text, you get a proper workspace: select any passage, mark it for deletion to cut scope, leave an inline comment, or write a replacement. Your annotations export as structured feedback that goes straight back to the agent — no copy-pasting or retyping — and every revision is saved with version history and a diff view showing what changed between iterations. On the code side, /plannotator-review opens a PR-style viewer over your agent's uncommitted local changes or a GitHub/GitLab PR URL, with side-by-side or unified diffs, file-tree navigation, line-level annotations that can carry code suggestions, and staging or unstaging before you commit. It also annotates arbitrary markdown, folders, or URLs, and the agent's last message. Everything runs on your machine, so plans never leave it; shared links are encrypted with the data living in the link itself. There are integrations for VS Code (editor tabs, diff view, editor annotations), Obsidian (auto-save to your vault with frontmatter and tags), Bear, and GitHub PRs, and it works with Claude Code, Codex, Copilot, Amp, Droid, Gemini, Kiro, OpenCode, and Pi. The local plugin is free and open source under MIT/Apache-2.0; a hosted team layer called Workspaces is on a waitlist.
Ideal use cases:
- •Teams or individuals who need automatic hook into the agent's plan-approval step
- •Teams or individuals who need inline comments, scope deletions, and replacement text on any plan section
- •Teams or individuals who need structured feedback sent straight back to the agent
- •Teams or individuals who need version history with diffs between plan revisions
- •Anyone focused on code review workflows
- •Anyone focused on coding agents workflows
