# Transition guides

> Plan a transition from Runloop to another execution platform

<Warning>
  Runloop is winding down its services. Transition support for existing customers continues through November 13, 2026 at 11:59 PM PT. Contact [Runloop support](mailto:support@runloop.ai) for assistance.
</Warning>

These preliminary guides map Runloop primitives to alternative platforms. They describe work to plan and checks to run; they do not certify a tested migration.

<CardGroup cols={2}>
  <Card title="Reflex to OpenAI Agents API" icon="right-left" href="/docs/transitions/reflex-to-agents-api">
    Build familiar Reflex workflows with OpenAI-managed sessions, personas, and connected tools.
  </Card>

  <Card title="Transition to Tensorlake" icon="right-left" href="/docs/transitions/runloop-to-tensorlake">
    Map devboxes, Axons, blueprints, snapshots, and legacy Benchmarks to a Tensorlake implementation.
  </Card>

  <Card title="Transition to Modal" icon="right-left" href="/docs/transitions/runloop-to-modal">
    Map the same primitives to Modal Sandboxes, Images, snapshots, and supporting infrastructure.
  </Card>

For side-by-side test specifications, use the [Tensorlake validation plan](/docs/transitions/runloop-to-tensorlake-validation) or [Modal validation plan](/docs/transitions/runloop-to-modal-validation). Start with the executable [Tensorlake comparison script](https://github.com/runloopai/runloop-examples/blob/main/transitions/runloop-to-tensorlake/compare_core_public.py) or [Modal comparison script](https://github.com/runloopai/runloop-examples/blob/main/transitions/runloop-to-modal/compare_core_public.py) in `runloop-examples` for command execution and UTF-8 file round trips, then extend coverage using the validation plans.
