High performance
linux machines.
Stealth browsers and isolated Linux environments that spawn in under a second for humans and agents.
Try it. Right now.
LIVE_SANDBOX_INSTANCE. REQUEST ACCESS TO ENGAGE.
A real Linux
machine.
Not a restricted container. Root access, persistent storage, and a real kernel — because your agent deserves the same environment you'd SSH into.
Invisible to
every detector.
Most automation fails because it's detectable. Chaser's browser environment is hardened at the hypervisor level — indistinguishable from real user hardware because it is real hardware.
Your stack,
unchanged.
Three surfaces of execution. One session. Use whichever interface your workflow demands — the execution environment is always the same real machine.
ssh real-ssh@ssh.chaser.shcurl -X POST https://api.chaser.sh/v1/sessions \
-H "Authorization: Bearer $CHASER_API_KEY" \
-d '{"session_type": "sandbox"}'
# → { "id": "ws_7f3a9c2e", "state": "running" }Give your agents
a real place to work.
Persistent sandboxes that feel like your machine. The session disk survives VM shutdown — attach, detach, resume. Your agent's state is never lost.
Persistent storage
Workspace disks survive shutdown. Resume exactly where you left off.
Hypervisor isolation
Every session runs in its own microVM. Real kernel boundary, not cgroups.
Live observation
Watch terminal output and browser video streams in real time from the dashboard.
No compromises
The fastest single core performance on the planet for your agents.
Engineered for
inevitability.
True speed doesn't come from hiding progress bars. It comes from removing friction from the system itself.
Install in seconds.
One command to own your infrastructure.
Agent Configuration.
Instant, automatic MCP configuration across your stack.
Infrastructure at
every scale.
No hidden costs. Pay only for the compute you actually provision.
