Runloop (winding down)
Runloop is winding down its services. Per its documentation, transition support for existing customers continues through November 13, 2026, 11:59 PM PT, and its docs include migration guides to Tensorlake, Modal and Freestyle. Not recommended for new projects. Closest alternatives: Freestyle, Modal Sandboxes, Daytona.
Status: Runloop is winding down its services. Per its documentation, transition support for existing customers continues through November 13, 2026, 11:59 PM PT, and its docs include migration guides to Tensorlake, Modal and Freestyle. Not recommended for new projects.
Overview
Runloop offered microVM Devboxes for coding agents, with blueprints, snapshots and agent-benchmarking tools. In 2026 it announced it is winding down; transition support ends November 13, 2026.
If you are migrating, Runloop’s own guides point to Tensorlake, Modal and Freestyle. For devbox-style persistent workspaces, also consider Daytona, E2B and Fly.io Sprites. See Runloop alternatives.
Notable
- Wind-down announced in 2026; transition support ends November 13, 2026.
- Freestyle offers Runloop customers $1,000 in credits.
