J. Scott Miller 1ab4ed8db5 feat: exclude AI Bridge usage from AI Governance seat counting (#27280)
Under the new `ai-gateway-seat-exclusion` experiment, AI Bridge usage
stops counting toward AI Governance seats.

## Seat recording

Under the experiment, `RecordInterception` no longer records
`ai_seat_state` usage for the initiator: AI Gateway access is licensed
by the AI Governance add-on rather than per seat. This experiment is
independent of `workspace-capable-licensing` (#27279) so the two
licensing behaviors can be enabled separately. Task workspace builds
still claim AI Governance seats.

## Manual verification

Verified live on a dev deployment (provider chained to dev.coder.com's
gateway, model `gpt-5.6-luna`): with the experiment off, the first
bridge request from each identity type (admin, plain member, service
account) wrote an `ai_seat_state` row (`aibridge` reason); with it on,
requests recorded interceptions but left seat state untouched — no new
rows, and existing rows' `last_used_at` did not advance.

Part of the gateway-accounts feature.

## Stack

Part 2 of the gateway-accounts stack:

1. **#27279**: permission-based license seat counting. Behind the
`workspace-capable-licensing` experiment and gated on the AI Governance
add-on, `user_limit` counts only users the RBAC engine authorizes to
create workspaces.
2. **This PR**: stops AI Bridge usage from claiming AI Governance seats
under the new `ai-gateway-seat-exclusion` experiment.
3. ~~**#27281**: adds a `use_shared` capability precondition for
workspace ACL grants, so workspace sharing is ineffective for (and
rejected toward) users without workspace capabilities, evaluated live on
every authorization.~~ This will be done in follow-up work when we have
time to look into the performance impact.

Related but independent: **#27278** hides the Workspaces page create
CTAs for users without workspace-create permission.

About

Coder is a self-hosted platform for running AI coding agents and cloud development environments on infrastructure you control. It works with any cloud, IDE, OS, Git provider, and IDP.

Coder Workspaces

Coder Workspaces are cloud development environments defined with Terraform, connected through a secure Wireguard tunnel, and automatically shut down when not in use. Agents and developers share the same workspace infrastructure.

  • Defined in Terraform: Templates describe the infrastructure for each workspace, from EC2 VMs and Kubernetes Pods to Docker containers.
  • Any architecture and OS: Support ARM and x86-64 across Windows, Linux, and macOS from a single deployment.
  • Managed by admins: Platform teams create and maintain templates that enforce approved images, resource limits, and security policies.
  • Accessed from any IDE: Connect through VS Code, JetBrains, Cursor, a web terminal, remote desktop, or SSH.
  • Automatic shutdown: Idle workspaces stop automatically to reduce cloud spend, and restart in seconds when needed.

Coder Agents

Coder Agents is a native AI coding agent built into Coder. The agent loop runs in the Coder control plane on your infrastructure, not in the workspace and not in a vendor's cloud. Developers interact with agents through the web UI or the REST API for programmatic and CI-driven workflows.

  • Self-hosted agent loop: The control plane handles planning, model calls, and tool dispatch. Workspaces have zero AI awareness.
  • No API keys in workspaces: LLM credentials stay in the control plane.
  • Any model: Anthropic, OpenAI, Google, Bedrock, or self-hosted endpoints. Switching is a configuration change.
  • Governance and cost controls: Centralized model approval, per-user spend limits, and audit logging.
  • Open source and inspectable: The full platform is available to audit and extend.

Why remote development

Provisioning consistent development environments for a large engineering team is difficult. Each developer has preferences for operating systems, editors, and toolchains, and ensuring a reliable build environment across all of them is a maintenance burden. A missed step during onboarding or an unsupported local configuration can cost hours of debugging.

Remote development solves this by moving the environment off the developer's machine and into managed infrastructure. The developer's laptop becomes a portal into the actual compute where work happens. If a device is lost or replaced, access is simply revoked; no source code or credentials are stored locally.

This approach provides:

  • Speed: Server-grade hardware accelerates builds, tests, and large workloads without requiring expensive local machines.
  • Consistency: Infrastructure tools such as Terraform, nix, Docker, and Dev Containers produce identical environments for every developer.
  • Security: Source code stays on private servers. Users and groups are managed through SSO and RBAC.
  • Compatibility: Workspaces share infrastructure configurations with staging and production, reducing configuration drift.
  • Accessibility: Browser-based IDEs and remote IDE extensions let developers work from any device, including lightweight laptops, Chromebooks, and tablets.

Why Coder

The key difference between Coder and other platforms is that the entire system, agent loop, control plane, model routing, and workspace provisioning, runs on infrastructure you control.

For agents, this means platform teams can:

  • Run the entire agent loop on their infrastructure, with no SaaS dependency for orchestration.
  • Define MCP servers, skills, and system prompts centrally so every agent session starts with the same tools, policies, and context.
  • Keep LLM credentials out of workspaces entirely.
  • Tie every agent action to an authenticated user identity.
  • Support air-gapped and restricted-network deployments with self-hosted models.

For workspaces, this means admins can:

  • Support any architecture (ARM, x86-64) and operating system (Windows, Linux, macOS).
  • Modify pod/container specs, such as adding disks, managing network policies, or setting/updating environment variables.
  • Use VM or dedicated workspaces, developing with Kernel features (no container knowledge required).
  • Enable persistent workspaces, which are like local machines, but faster and hosted by a cloud service.

Pricing

Coder is free and open source under the GNU Affero General Public License v3.0. All developer productivity features are included in the open source version. A Premium license is available for enhanced support and custom deployments.

How Coder works

Coder workspaces are represented with Terraform, but you do not need to know Terraform to get started. The Coder Registry provides production-ready templates for AWS EC2, Azure, Google Cloud, Kubernetes, and other providers.

Providers and compute environmentsProviders and compute environments

Workspaces can include more than just compute. Terraform can add storage buckets, secrets, sidecars, and other resources.

See the templates documentation for details.

What Coder is not

  • Coder is not an infrastructure as code (IaC) platform.

    • Terraform is the first IaC provisioner in Coder, allowing Coder admins to define Terraform resources as Coder workspaces.
  • Coder is not a DevOps/CI platform.

    • Coder workspaces can be configured to follow best practices for cloud-service-based workloads, but Coder is not responsible for how you define or deploy the software you write.
  • Coder is not an online IDE.

    • Coder supports common editors, such as VS Code, vim, and JetBrains, all over HTTPS or SSH.
  • Coder is not a collaboration platform.

    • You can use Git with your favorite Git platform and dedicated IDE extensions for pull requests, code reviews, and pair programming.
  • Coder is not a SaaS/fully-managed offering.

    • Coder is a self-hosted solution. You must host Coder in a private data center or on a cloud service, such as AWS, Azure, or GCP.
