Wago compared with wazero
A scoped, source-linked comparison of Wago and wazero, including when to choose either runtime and what has not been benchmarked.
Short answer
Choose Wago when you are evaluating Wago’s single-pass compile latency, instance-allocation profile, plugin model, or its current benchmarked host-call path.
Choose wazero when you need a stable v1 API promise, a mature pure-Go runtime with a broader production history, or a portable interpreter on additional Go targets.
Operational differences
| Area | Wago | wazero |
|---|---|---|
| Implementation | Go; no cgo | See the project’s current implementation and bindings |
| Execution terminology | Single-pass native compiler | Go-native compiler backend, with a portable interpreter fallback |
| Wago release maturity | Pre-v1 development/nightly channels; no stable v1 API promise | See the other project’s release and support policy |
| Known Wago gap | Wago is pre-v1 and does not match wazero’s platform breadth or published API-stability promise. | Not applicable |
