Developer Platform
Choose your developer kit and version
Download the current public kit, understand version numbers, or get a kit scoped to your tenant account.
Use the public Developer Kit to build a website, backend integration, or custom frontend for your SaaS. Use the account kit when you need the runtime contract and pages available to one tenant account.
Download the current public Developer Kit
The current release is 1.20.3. Download Developer Kit 1.20.3. The archive includes OpenAPI, the SDK, React and Puck examples, API instructions, and executable integration examples. It contains no database credentials or API tokens.
Read version numbers as separate parts
Versions use major.minor.patch, not decimal numbers. Version 1.20.3 is later than 1.9 and 1.2: minor version 20 comes after 9 and 2. Old release notes deliberately retain their original versions; they do not identify the latest download.
When to use an account-specific kit
An active account owner can open Admin → Developer kit inside the SaaS. That ZIP describes the account's current enabled modules, pages, menus, bindings, and tenant-runtime contracts. It is generated on request and is not simply an older public kit. See Account administration for its contents and setup.
Upgrade without losing your customizations
- Read the release notes and keep your existing project in source control.
- Extract the new ZIP into a separate directory. Compare its OpenAPI, manifest, SDK, and examples with the version you use.
- Merge relevant changes into your project; do not overwrite custom pages or configuration with sample files.
- Run the checks documented in the kit and verify your integration against your test account before deployment.
The kit version identifies the downloadable package. API URLs still use their documented /v1/ prefix; a new ZIP does not change the route version. See API operating contracts for contract fingerprints and compatibility.
Start with your task
- Make your first API request.
- Sign up customer organizations from your website.
- Customize React, CSS, and page design.
- Receive webhooks and poll background jobs.
