## What it is
IHP is a batteries-included, type-safe full-stack web framework built on Haskell and Nix, featuring compile-checked HTML (HSX), typed SQL queries, schema-generated records, and built-in authentication, forms, and code generators. It is optimized for rapid development with live reloading, a web-based schema designer, and AI-agent-friendly conventions shipped via AGENTS.md/CLAUDE.md.

## Use cases
- build a type-safe full-stack web application in Haskell
- rapidly prototype a CRUD web app with database, auth, and forms
- catch invalid SQL and HTML errors at compile time
- build real-time dashboards that auto-refresh when data changes
- set up a reproducible dev environment with Nix and PostgreSQL
- use AI coding agents with compiler-verified code generation
- build JSON APIs for mobile apps and SPAs

## When to choose
- you want compile-time guarantees for routing, queries, and HTML
- you want a batteries-included MVC framework with auth, migrations, and dev tools out of the box
- your team is open to Haskell or wants to learn it with a gentle on-ramp
- you want reproducible environments via Nix with zero setup friction
- you use AI coding assistants and want the type system as a safety net

## When to avoid
- your team has no appetite for learning Haskell
- you need a language with a large hiring pool or ecosystem of off-the-shelf libraries
- you need databases other than PostgreSQL (MySQL/MSSQL support is paid/coming soon)
- you need fine-grained control over every framework component rather than opinionated conventions
- some advanced features (RBAC, i18n, Stripe) require paid licenses for commercial use
