Runloop alternative for always-on AI agents

Runloop is built for teams whose product is a coding agent. Devboxes start fast and run on micro-VM isolation, blueprints make environments reproducible and Repo Connect detects how to build a repository on its own. The benchmark layer is the rare part: you can score an agent on SWE-Bench, R2E-Gym or SWE-Smith, or turn your production data into a custom benchmark, then use the results for reinforcement fine-tuning.

The enterprise story is solid too: SOC 2 Type II, HIPAA and GDPR, a credential gateway that injects tokens the agent never sees, per-devbox egress policies and VPC deployment on the three big clouds.

Runloop's own docs describe devboxes as ephemeral by definition. A devbox lives for one hour by default, suspend keeps the disk without the memory and daemons running at suspend time have to be restarted by hand after resume. Keeping one running all month costs about $233 of compute for a 2 CPU, 4 GB devbox at list rates and suspend and resume need the $250 Pro plan.

An autonomous agent needs a process that stays alive, a supervisor that restarts it, schedules that fire on time, memory and files that survive upgrades, logged-in tools and an identity. Molted ships that layer as a product: 4-tier self-healing with a post-mortem on every failure, config auto-repair, a versioned filesystem with point-in-time restore, 1,500+ managed integrations, managed browser automation and a mailbox and phone number per agent.
