Show HN: SynapsCLI – lightweight agent runtime in Rust, control an agent swarm
github.comSynaps is an agent runtime written in Rust. It keeps cost down by optimising caching mechanisms and intelligently orchestrating work across workers. This keeps each worker's context low and fresh, making sessions last longer. It is extremely extensible. It has hooks, plugins and skills that can be imported from pretty much any coding tool.
It is an open source project that was started 4 months ago. It was built to optimise for 2 things: Keeping LLM costs down, and keeping resource use low. It bots up in 20ms and runs with any model: OAuth(codex, Grok, Kimi...), api keys or local models too. This is something that was built organically, so every feature is a product of necessity, not the other way around.
is this an LLM router deployed as an AI agent?
No, it's more of a harness than a router. It owns the agent loop, sessions, extensions, skills and more. It's closer to claude code or codex cli rather than an LLM router.
