Developer resources

Everything Pylon publishes for people writing code, and for the agents writing it with them. All of it is public, free, and usable without an account.

Build with Pylon

Pylon documentation

Every concept, from entities and policies to auth, plugins, clients, and operations.

Add .md to any page URL to read it as markdown.

Pylon CLI

The official command line tool: dev, build, test, verify, deploy, logs, secrets, domains, and database backups.

npm create @pylonsync/pylon@latest my-app — or curl -fsSL https://www.pylonsync.com/install.sh | bash for the global binary. Every command takes --json.

Starter templates

Eighteen working apps: SaaS, chat, shop, marketplace, directory, CRM, helpdesk, AI chat, and more.

npm create @pylonsync/pylon@latest my-app --template saas

Source on GitHub

The Rust runtime, the TypeScript SDKs, the templates, and the example apps. MIT licensed.

Changelog

What shipped, release by release.

For agents

Pylon is built for coding agents, so its own site answers machines directly. Nothing below needs a key, a signup, or a rate-limit exemption.

Pylon agent skill

One markdown file that teaches a coding agent to write Pylon that compiles: the schema DSL, the policy language, the function flavors, the hooks, and the footguns.

Read it at /pylon-skill.md, or load it into Claude Code as a skill.

llms.txt

What Pylon is for, when to reach for it, and where everything else lives — in the llmstxt.org format an agent reads first.

Pylon MCP server

A remote Model Context Protocol server over Streamable HTTP. Four read-only tools: search the docs, read a page, list templates, fetch the skill. No account, no key.

claude mcp add --transport http pylon https://www.pylonsync.com/mcp

Pylon agent API (OpenAPI 3.1)

The same four operations as plain HTTP GETs under /agent/v1, with unique operation ids, typed parameters, and response schemas for function calling.

curl 'https://www.pylonsync.com/agent/v1/docs/search?q=policies'

Markdown pages

Every page on this site is also readable as markdown, with no navigation or scripts around it.

Add .md to any path, or send Accept: text/markdown.

Connect an agent in one command

Point Claude Code, or any MCP client, at the hosted server. It exposes four read-only tools and needs no credentials.
