Why We Built a Dedicated Execution Engine Instead of Embedding Code Runners Everywhere

In many platforms, code execution appears as a secondary feature: scripts inside services, plugins inside apps, or embedded runtimes glued into existing systems.
We took a different path with GozoLite: treating execution as a first-class infrastructure capability.
Instead of distributing execution logic across multiple services, we centralized it into a dedicated execution engine with explicit operational boundaries.
This decision came from observing recurring issues in distributed execution setups:
inconsistent isolation guarantees
duplicated runtime handling
unclear failure modes
fragmented observability
security drift across services
By isolating execution into a focused engine, we gained:
Deterministic execution contracts
Every run follows the same submit() model with explicit limits and outcomes.
Uniform sandboxing
CPU, memory, time, and output limits enforced consistently across 30+ runtimes.
Operational clarity
Execution lives in one deployable unit with predictable scaling and failure behavior.
Security boundaries
Clear separation between host platform and untrusted code execution.
Observability surfaces
Health, diagnostics, capabilities, and structured execution logs exposed natively.
This architecture turns code execution from an embedded feature into a reusable platform capability.
Instead of each service reinventing safe execution, the platform provides it once — correctly and observably.
That shift changes how systems evolve: execution becomes composable infrastructure, not scattered logic.
