Wasm-native sandboxes for AI agents.
Sub-millisecond execution. Cryptographic receipts. Self-hostable.
synapserun.dev · github.com/Synapse-Run/cell · hello@synapserun.dev
AI agents need to execute code. Today that means cloud sandboxes that boot a Linux kernel per request — slow, expensive, and opaque.
Synapse Run is a Wasm-native replacement. Code runs inside a sandboxed WebAssembly arena on bare metal — no kernel, no container, no cold start — at sub-millisecond p50 latency. Every execution produces a SHA-256 receipt, so the execution chain can be audited.
cell — the flagship runtime: the Wasm sandbox, the E2B-compatible SDKs (Python + JS), and the deployment story. Public, AGPL-3.0 + Apache-2.0 dual licensed, with a commercial license available for closed-source deployments.
| Layer | License |
|---|---|
| Core runtime, .syn compiler, SDKs | Apache 2.0 |
| Pro features (heavy FFIs, persistent sessions) | AGPL v3 |
| Hub features (fleet, federation, audit-grade receipts) | AGPL v3 |
| Closed-source commercial deployments | Commercial dual-license |
Everything is self-hostable for free under AGPL. The commercial license is the path for organizations that want to ship Cell inside closed-source products. We don't gate access — we charge for convenience (managed hosting), compliance (audit-grade receipts), and the right to keep modifications proprietary. See the Manifesto for the values that drive these choices.
"Synapse Cell," "EdgeCell," and "Synapse Hub" are unregistered trademarks of the Synapse Run project. See the Trademark Policy for what you can and can't do with these names.
Vulnerabilities go through private vulnerability reporting, not public issues. See our org-wide SECURITY.md. Acknowledged in 48 hours; high-severity fixes within 14 days; coordinated public disclosure on patch.
Synapse Run is maintained by independent contributors in Canada. The corporate vehicle is in formation.
