zeroshot vs roam-code
zeroshot has 2,090 GitHub stars, 198 forks, 3 open issues and last shipped yesterday. roam-code has 516 stars, 50 forks, 12 open issues and last shipped 3 days ago. zeroshot leads on adoption by 305% (2,090 vs 516 stars). zeroshot is written in Rust under MIT; roam-code is written in Python under Apache-2.0. zeroshot has attracted 9% as many forks as stars, roam-code 10%. zeroshot was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 3 topic tags (ai-agents, code-quality, code-review), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About zeroshot
Zeroshot The agent that writes the code should not be the one that decides it works. Zeroshot turns a software goal into an explicit multi agent graph: one agent implements, independent agents review, failures go back to a bounded repair loop, and nothing is delivered until the graph's checks pass. The implementing agent never approves its own work. Use the built in graph or bring your own topology. Add reviewers, tests, and repair loops, then save the setup as a profile for the next task. Opcore works alongside it: Opcore checks each edit while an agent writes code, and Zeroshot has independent agents review…

About roam-code
roam code Local code analysis and ready to run checks for coding agents. Roam gives your agent a reusable codebase index, pattern findings, candidate algorithmic alternatives, and checks it can call as it works. It can investigate code and evaluate changes without building each analysis from scratch.
