OnceRun once. Reuse anywhere.

Once makes repository automation reusable across developers, coding agents, and machines by giving each action explicit inputs, outputs, environment, and execution policy.

Get started

Why Once

Remote execution

Reference

Start with a script

Add an input and output contract to automation that already works, then run it through Once.

Reuse the result

Restore content-addressed outputs locally or through a shared cache when the declared inputs have not changed.

Run somewhere else

Send only declared inputs to a fresh local or hosted sandbox, retrieve declared outputs, and delete the machine.

Grow into a graph

Move workflows into typed targets and capabilities when they need richer dependencies, queries, and diagnostics.
