## What it is
Biff is an opinionated full-stack web framework for Clojure aimed at solo developers. It curates ecosystem libraries (XTDB, htmx, Malli) into a cohesive whole with batteries-included auth, deployment, and REPL-driven development.

## Use cases
- build a full-stack web app in clojure
- launch a side project quickly as a solo developer
- passwordless email authentication with magic links
- server-rendered interactive ui with htmx
- deploy a clojure app to a vps or docker
- develop a web app live via repl

## When to choose
- you're a solo developer or small team building a web app in Clojure
- you want an opinionated, batteries-included stack with auth and deployment out of the box
- you like REPL-driven, iterative development
- you want immutable/document-style storage with XTDB and schema enforcement via Malli

## When to avoid
- you need a large team-friendly, unopinionated framework with flexible library choices
- your project isn't in Clojure
- you need heavy client-side SPA frameworks rather than server-rendered htmx UIs
- you require a mature v2 — Biff 2 is still in development

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, auth, templating, http-server, orm, deployment
- domain: web-development, backend, developer-tools
- platform: jvm-scripting, self-hosted
- tags: xtdb, htmx, malli, solo-developer, repl-driven-development, full-stack, linux, docker, web-server
