EU-hosted autonomous coding agents that run in their own microVMs with network access restricted unless explicitly configured.

ainclave runs autonomous coding agents in isolated microVMs where network egress is closed by default. Each agent session gets its own Firecracker microVM with its own guest kernel, so there's no shared kernel namespace between sessions. You point an agent at your git repo, bring your own model token from any provider, set optional runtime caps, and let it work without babysitting.
It's built for developers and teams who want to automate code tasks (writing, testing, refactoring) without the operational overhead of self-hosting or the security blind spots of shared cloud runners. You keep full control: your token stays encrypted, your repo access is scoped, your agent's network access is explicit and auditable.
Key capabilities:
The trade-off between control and convenience is real in most platforms. ainclave tries not to accept it: you get full control over agent permissions and visibility without managing infrastructure yourself. Standard git flow, no lock-in, no runners to keep alive.
