Use Case Recommendations
Best for: Devin
Autonomous AI software engineer from Cognition AI that can complete entire coding projects. Devin plans, writes code, debugs, tests, and deploys applications with minimal human oversight.
Ideal use cases:
- •Teams or individuals who need autonomous coding
- •Teams or individuals who need end-to-end projects

- •Teams or individuals who need learn new technologies
- •Anyone focused on coding workflows
- •Anyone focused on ai agent workflows
Best for: Stoneforge
Stoneforge is an open-source orchestration layer for running several AI coding agents at once on the same repository. The failure mode it targets is specific: once you have more than one Claude Code, Codex, or OpenCode session working on a project, they edit the same files on the same branch, two of them grab the same task, and you cannot see what any of them is doing without tabbing through terminals. Stoneforge fixes each of those in turn. Every worker agent runs inside its own isolated git worktree, so agents never collide on the filesystem, and a merge steward handles integration back to main — reviewing CI status and resolving conflicts as a separate role rather than leaving it to whichever agent finished first. A dispatch daemon tracks task priorities and dependencies and auto-assigns ready work to idle workers, so nothing gets double-claimed and nothing starts while it is still blocked. Over the top sits a real-time web dashboard at localhost:3457 that shows active agents, tasks in progress, merge requests awaiting review, and recent completions in one view, with a command palette for driving the whole thing. Roles are explicit — Director agents execute plans, Workers implement, Stewards review and merge — and recent versions added GitHub, Linear, and Notion sync so the task board can mirror the tracker a team already uses.
Ideal use cases:
- •Teams or individuals who need every worker agent runs in an isolated git worktree, eliminating cross-agent merge conflicts
- •Teams or individuals who need merge steward role reviews ci status and resolves conflicts before integrating to main
- •Teams or individuals who need dependency-aware dispatch daemon auto-assigns ready tasks to idle workers
- •Teams or individuals who need real-time web dashboard showing active agents, tasks, merge requests, and completions
- •Anyone focused on ai-agents workflows
- •Anyone focused on coding-agents workflows
