A collection of tools for FileMaker-aware TypeScript applications

For new and experienced developers alike, the ProofKit toolset is the best way to build web apps connected to FileMaker data, or rich, interactive interfaces in a FileMaker webviewer.

ProofKit CLI

A command line tool to start a new project, or easily apply templates and common patterns with no JavaScript experience required.

Typegen

Automatically generate runtime validators and TypeScript files from your own FileMaker layouts or table occurrences.

Filemaker Data API

A type-safe API for your FileMaker layouts. Easily connect without worrying about token management.

FileMaker OData API New

A strongly-typed OData API client with full TypeScript inference, runtime validation, and a fluent query builder.

FileMaker Webviewer

Use async functions in WebViewer code to execute and get the result of a FileMaker script.

Better-Auth Adapter Beta

Own your authentication with FileMaker and the extensible Better-Auth framework.

Quick Start

Use the ProofKit CLI to launch a full-featured Next.js app in minutes—no prior experience required.

pnpm create proofkit@beta
npx create-proofkit@beta
yarn create proofkit@beta

Built for AI Agents

Every ProofKit package ships with agent skills — built from decades of combined FileMaker integration experience at Proof+Geist — that give AI coding tools like Claude Code and Cursor the context they need to write correct, production-ready FileMaker code from day one.

Expert knowledge built in

Agent skills cover API patterns, edge cases, and common mistakes so your AI agent avoids the pitfalls that trip up even experienced developers.

Type-safe by default

Schemas generated from your FileMaker field names plus runtime validators catch bugs early — whether code is written by you or your AI agent.

Works with any agent

Skills are bundled with each package — just install and your AI coding tool picks them up automatically. Compatible with Claude Code, Cursor, Windsurf, and more.
