The secure language for AI agents — without giving up speed

Most stacks make you choose: fast, or safe. Synsema is both — top-tier throughput with capability security built into the language itself.

Throughput (100 concurrent connections)

Synsema, Go and Node are all in the same top tier (the gaps are run-to-run noise) — and Synsema is ~1.5x FastAPI under load. Async-native, true multi-core, a single static binary with zero runtime.

The difference: secure by default

Speed gets you into the room. What no other top-tier stack offers: deny-by-default capabilities, declarative auth and validation, sandboxing, and a frozen intent. Security is a property of the language — not a discipline you have to remember. That's why Synsema is the best fit for AI-agent backends and any service handling untrusted input.
