Bastion review: Infrastructure layer for running background coding agents inside isolated Linux virtual machines, with templates, environment provisioning, SSH or OpenCode access, and per-agent environment control.
Bastion stands out because it is not just another chat shell. The product materials describe a system centered on define a template for a codebase and toolchain, provision agent environments from that template, let each agent run in its own vm, then connect through the bastion cli, ssh, or opencode while services stay isolated per environment. That matters because the mechanism is the product, not a thin wrapper around a frontier model.
Why the architecture matters
Bastion is explicit that the product is isolated compute for background coding agents, not just another wrapper around a single IDE session. The docs are unusually practical about templates, environment creation, SSH access, and proxying services out of agent VMs. The VM boundary is the main value: each agent gets full control of its own workspace without colliding with the others on ports, files, or processes.
How to evaluate the core loop
Start by testing the narrowest real workflow the product claims to improve. For Bastion, that means users should define a template for a codebase and toolchain, provision agent environments from that template, let each agent run in its own vm, then connect through the bastion cli, ssh, or opencode while services stay isolated per environment. The result should be easier to inspect, integrate, or control than a direct agent session.
Where it stands out
| Evaluation angle | Fit | Why it matters | | --- | --- | --- | | Best-fit user | High | Engineering teams that want coding agents to keep working in parallel without sharing a local workstation state or fighting over one mutable development environment. | | Core workflow clarity | High | Define a template for a codebase and toolchain, provision agent environments from that template, let each agent run in its own VM, then connect through the Bastion CLI, SSH, or OpenCode while services stay isolated per environment. | | Switching cost reducer | Medium to high | Bastion is explicit that the product is isolated compute for background coding agents, not just another wrapper around a single IDE session. | | Adoption risk | Medium | The value depends on teams already running enough parallel agent work to justify dedicated remote environments instead of a single local setup. |
Practical use cases
- Running several background coding agents without runtime conflicts
- Giving each agent an isolated VM with its own services and dependencies
- Managing reusable environment templates for agent-driven dev work
Limits and buying notes
The value depends on teams already running enough parallel agent work to justify dedicated remote environments instead of a single local setup. Prospective users should verify pricing, region support, and operational overhead before moving steady engineering workflows onto it. Pricing status today: The reviewed public pages describe Bastion's product and CLI but did not expose a public pricing table, so current commercial terms need to be confirmed directly with the company.
FAQ
What is Bastion best for?
Bastion is strongest when running several background coding agents without runtime conflicts matters more than a generic AI demo. The official product materials position it around a concrete workflow rather than a blank chatbot shell.
Who should try Bastion first?
Engineering teams that want coding agents to keep working in parallel without sharing a local workstation state or fighting over one mutable development environment. Teams with a real workflow match will get value faster than general curiosity users.
What should buyers verify before adopting Bastion?
The value depends on teams already running enough parallel agent work to justify dedicated remote environments instead of a single local setup. Prospective users should verify pricing, region support, and operational overhead before moving steady engineering workflows onto it. Pricing, privacy, and workflow fit should be checked directly on the current product before rollout.
