Title: Developer Docs Description: Find the architecture, setup, API, frontend, backend, testing, contribution, and release documentation for OpenPost. Canonical: https://docs.openpo.st/development/ Source: [https://docs.openpo.st/development/](https://docs.openpo.st/development/) # Developer Docs Use these docs when you are changing OpenPost itself: backend routes, platform adapters, frontend components, generated clients, MCP tools, billing infrastructure, database migrations, tests, or release behavior. Developer docs are separate from user-facing docs and self-hosting docs. They can assume repository access, local toolchains, and willingness to run checks. ## Start here - [Development Setup](https://docs.openpo.st/development/setup) gets the repo, frontend, backend, and docs running locally. - [Architecture](https://docs.openpo.st/development/architecture) explains the main boundaries. - [Contributing](https://docs.openpo.st/development/contributing) covers contribution workflow. - [Testing](https://docs.openpo.st/development/testing) covers local and CI checks. - [Releases and Versioning](https://docs.openpo.st/development/releases) covers SemVer, production releases, and failure handling. ## Backend and API - [Backend](https://docs.openpo.st/development/backend) covers Go backend conventions. - [API Reference](https://docs.openpo.st/development/api-reference) renders the generated OpenAPI spec. - [API Tokens](https://docs.openpo.st/development/api-tokens) documents one-time secrets, expiry, scopes, workspace boundaries, and revocation. - [Background Jobs](https://docs.openpo.st/development/background-jobs) covers durable job behavior. - [Platform Adapters](https://docs.openpo.st/development/platform-adapters) covers provider integration rules. - [Billing and Usage](https://docs.openpo.st/development/billing-and-usage) covers entitlements, usage counters, and hosted billing primitives. ## Frontend, MCP, and launch work - [Frontend](https://docs.openpo.st/development/frontend) covers SvelteKit app conventions. - [MCP and ChatGPT App](https://docs.openpo.st/development/mcp) covers tool-server and Apps SDK integration notes. - [Production Architecture](https://docs.openpo.st/development/production-readiness) records shared hosted and self-hosted architecture, provider verification, and release checks. ## Adjacent docs - If you are using OpenPost through the web app, CLI, or MCP client, start with [User Docs](https://docs.openpo.st/usage/). - If you are deploying or operating an instance, start with [Self-Hosting Docs](https://docs.openpo.st/self-hosting/).
