IHP, a batteries-included web framework built on Haskell and Nix

IHP is the Haskell web framework for agentic engineering. Your agent writes the code; typed SQL, generated schema types and compile-checked views prove it works.

In plain words

IHP is a web framework that combines Haskell and Nix to provide a complete development environment out of the box. It is designed for developers who want to build web applications using Haskell's strong type system and functional programming approach. The framework bundles together all necessary tools and dependencies, eliminating common setup challenges and allowing developers to start building immediately.

-- Your agent wrote this: posts <- sqlQueryTyped [typedSql| SELECT id, title, publish_date FROM posts |] error: [GHC-39584] • typedSql: prepare failed: ERROR: column "publish_date" does not exist LINE 1: SELECT id, title, publish_date FROM posts ^ This never reaches production. typedSql asks your Postgres to describe the query while your code is still compiling. An agent produces more code in an afternoon than a team can review in a week. The bottleneck was never typing speed — it's knowing the code is correct. In most stacks the answer is "run it and find out." In IHP the answer is: it doesn't compile. Every query is checked against your real Postgres schema at compile time.

    Hey HN, We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode. The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code. How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure Closest analog is Playwright codegen but: - Infrastructure…
