Which agent framework should you pick?
openclaw-rs next to the projects you're most likely evaluating — including ZeroClaw, the established Rust rewrite. Pick the column whose constraints fit yours.
| Capability | openclaw-rs | TS OpenClaw | LangChain | Mastra | Rig |
|---|---|---|---|---|---|
| Single static binary | ● cargo install, no runtime | ○ needs Node.js | ○ needs Python or Node | ○ Node.js backend | ● Rust library, embed it |
| Event sourcing core | ● sled append-only log | ◐ via storage abstractions | ○ ad-hoc / not core | ◐ via memory adapters | ○ library-level only |
| Platform sandbox for tools | ● bwrap / sandbox-exec / Job Objects | ○ process-level only | ○ out of scope | ○ out of scope | ○ library-level only |
| JSON-RPC HTTP + WS gateway | ● axum, in-binary | ◐ via plugins | ○ bring-your-own server | ◐ Next.js / Hono | ○ bring-your-own server |
| Encrypted credential store | ● AES-256-GCM + Argon2id | ◐ env-var / OS keyring | ○ user responsibility | ◐ env-var | ○ user responsibility |
| Input validation at boundary | ● size + depth + char limits | ◐ ad-hoc | ○ user responsibility | ◐ schema validation | ○ user responsibility |
| TypeScript plugin compat | ● nng IPC bridge | ● native TS | ○ no such concept | ○ no such concept | ○ no such concept |
| Node.js SDK from same core | ● napi-rs, prebuilt binaries | ● is the Node SDK | ● is JS-native | ● is JS-native | ◐ FFI wrappers possible |

vs TypeScript OpenClaw
The original — same plugins, same config, Node.js runtime.

The established Rust rewrite — small binary, broad providers.
Read the comparison → vs LangChain
A toolkit, not a runtime — Python/JS, broad ecosystem.
Read the comparison → vs Mastra
TypeScript backend framework — JS-native, embed in your Node app.
Read the comparison → vs Rig
Rust agent library — embed in your service, not deploy as a runtime.
