Adds the chat lifecycle hook wire contract and dispatch plumbing, first PR of the lifecycle hooks stack (followed by #27428, #27429, #27430). - `codersdk/x/agenthooks`: event and response wire types, JWT creation and verification with the shared secret (HS256, request body digest, expiry and not-before freshness checks), and an HTTP handler helper so consumers only implement the events they use. The `codersdk/x` location marks the consumer SDK as experimental. - `coderd/x/agenthooks/dispatch`: a stateless dispatcher that signs and posts hook events, enforces a concurrency cap under one configured timeout that bounds both the capacity wait and both post attempts, retries one connection failure with the same JWT, sends a distinctive `coderd-agenthooks/<version>` User-Agent, and records Prometheus metrics. Delivery is at least once; consumers own durable decision state, audit records, and deduplication keyed by the stable payload identifiers. Nothing is persisted by Coder. - Response bodies decode strictly: unknown fields, duplicate JSON keys (including inside `input_override`), and trailing data fail the dispatch closed as protocol errors instead of silently reading as allow. - `coderd/util/xnet`: shared timeout and connection error classification used by the dispatcher retry logic. Transient HTTP/2 stream aborts count as connection errors, so the documented single retry also applies to h2 consumers, which is the shape Go's default transport negotiates against any TLS consumer. Deterministic protocol failures stay terminal. Only the struct form of a stream error is matched, because `net/http` bundles its own HTTP/2 types and `h2_error.go` bridges only that shape. - `scripts/agenthooks-server`: a reference consumer that logs events and demonstrates consumer-owned pre-tool decision deduplication. It requires an explicitly configured JWT audience rather than deriving one from the request, and its startup output names the mode it is running in so an operator can see that the example policy flags need `-log-only=false`. - `scripts/apitypings`: generate TypeScript types for the hook wire contract. Dispatch failures log without the error's stack frames, since a failed dispatch is an expected, operator-visible condition. Nothing dispatches these events yet; chatd wiring lands in #27429. > This PR was written by Mux, an AI coding agent, on Mike's behalf.
Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.
- Define cloud development environments in Terraform
- EC2 VMs, Kubernetes Pods, Docker Containers, etc.
- Automatically shutdown idle resources to save on costs
- Onboard developers in seconds instead of days
- Delegate coding work to AI agents on your infrastructure
- Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
- No LLM credentials in workspaces, user identity on every action
- Centralized model governance, cost tracking, and audit logging
Quickstart
The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).
# First, install Coder
curl -L https://coder.com/install.sh | sh
# Start the Coder server (caches data in ~/.cache/coder)
coder server
# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace
Install
The easiest way to install Coder is to use the
install script for Linux
and macOS. For Windows, use the latest ..._installer.exe file from GitHub
Releases.
curl -L https://coder.com/install.sh | sh
You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.
See install for additional methods.
Once installed, you can start a production deployment with a single command:
# Automatically sets up an external access URL on *.try.coder.app
coder server
# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>
Use coder --help to get a list of flags and environment variables. See the install guides for a complete tutorial.
