See the comparison table for live GitHub stats and shared categories. ### When should I choose agency over chidori? Choose agency over chidori when agency is primarily Python; chidori is Rust; License: agency is MIT, chidori is Apache-2.0; Tags unique to agency: actor-model, autonomous-agents; When you prefer a lightweight solution for building autonomous agent systems without the need for extensive configuration or complex dependencies. ### When should I choose chidori over agency? Choose chidori over agency when chidori is primarily Rust; agency is Python; License: chidori is Apache-2.0, agency is MIT; Tags unique to chidori: checkpointing, deterministic, durable-execution, javascript-engine; When you need a self-contained binary tool for deterministic execution of AI agents with no additional setup like Node or Python environments. ### When should I avoid agency? If your development requires deeply integrated functionalities that would necessitate a heavier, more feature-rich framework. In scenarios where you need robust tooling for large-scale deployment and management as Agency does not offer extensive LLMOps (LLM Operations) capabilities beyond its minimalistic design. ### When should I avoid chidori? Avoid if your deployment environment strictly forbids running self-contained binaries, favoring interpreted scripts exclusively for flexibility reasons. Not suitable when a tool's native integration with Node.js or Python is critical and the project has no Rust context setup available. ### Is agency or chidori more popular on GitHub? chidori has more GitHub stars (1,362 vs 489). Stars measure visibility, not whether either tool fits your constraints. ### Are agency and chidori open source?
