Replicas vs running OpenCode yourself
OpenCode is an MIT-licensed agent that works with 75+ model providers. Run it yourself and you get full control, at the cost of building the VMs, isolation, triggers and pull-request plumbing. Replicas runs OpenCode (and Claude Code, Codex, Cursor, Pi and Muse Code) in a managed VM per task, started from Slack, Linear, GitHub or GitLab, and also offers self-hosting on Enterprise.
Checked against both vendors' docs and pricing as of November 9, 2026. This site is operated by Replicas.
Pick Replicas if
- You want OpenCode in the cloud without building VM provisioning, isolation and triggers yourself.
- You want SCIM, audit logs and a SOC 2 report from a vendor rather than building them.
- You want other agents next to OpenCode.
Pick OpenCode if
- Open source is a requirement for every part of the stack.
- You have a platform team that wants to own the infrastructure and integrations.
- You only need an agent in each engineer's terminal.

Still deciding?
The comparison above is the same for everyone. The chooser weights it by your team size, the agents you use, where work starts, how you pay for models and what your security review needs, and tells you which of the two, or something else, fits.

Which models can OpenCode use on Replicas?
Replicas runs OpenCode on OpenCode Go, OpenRouter or your own endpoint, and your provider bills the model usage.
