Alternatives
The right alternative depends on what you are replacing: price, AI quality, integrations, enterprise controls, or workflow focus. Start with the closest competitors, then use the related guides to narrow the decision.
Ranked by editorial fit, category overlap, and structured relationships.
Create isolated programmable computers for coding agents, interpreters, and untrusted workloads
Daytona provides API-controlled container, VM, Windows, and GPU sandboxes with dedicated filesystems, networking, lifecycle controls, snapshots, previews, and protected secrets.
Ephemeral cloud sandboxes for agents that execute code and use virtual computers
E2B isolates agent-generated code in disposable cloud environments, but network egress, secrets, persistence, images, concurrency, and usage cost still require production controls.
Run browser agents with managed sessions, proxies, profiles, credentials, replays, and observability
Steel is an open-source browser API and managed cloud runtime for AI agents, offering sessions, browser tools, proxies, CAPTCHA handling, persistent identity, and credential injection.
Look for an alternative if Runloop is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Shortlist two options, run the same real workflow through both, and keep the one that reduces rework rather than the one with the longest feature list.
