Why SynapseKit
Built for production Python
Designed for engineers who want full control without writing everything from scratch.
⚡
Async-native
Every API is async/await first. No sync-first retrofit. Sync wrappers included for scripts and notebooks.
🌊
Streaming-first
Token-level streaming is the default, not an afterthought. Works identically across all 27 LLM providers.
🪶
2 hard dependencies
numpy and rank-bm25 only. Every other capability is behind an optional extra. Install what you need.
🔌
One interface
27 LLM providers and 5 vector stores behind the same API. Swap providers without rewriting a single line.
💰
Cost intelligence
CostTracker and BudgetGuard give you full cost visibility and circuit-breaker budget limits — no SaaS required.
🚀
One-command deploy
`synapsekit serve my_app:rag` wraps any RAG pipeline, agent, or graph in a production FastAPI app instantly.
🧩
Fully composable
RAG pipelines, agents, and graph nodes are interchangeable. Wrap anything as anything.
🔍
No magic
No hidden chains, no callbacks, no global state. Every step is plain Python you can read and override.
