Overview
MDMA extends Markdown with interactive components written as short YAML inside fenced mdma blocks, so an LLM returns forms, tables, charts and approval gates instead of prose or JSON. Four core packages parse, validate, run and render the document, with renderers for React, Vue 3 and React Native. A deterministic validator runs first, and an LLM fixer repairs what it cannot auto-fix.
- Best for
- Developers building LLM-driven interfaces in React, Vue or React Native who need validated UI output.
- Pricing
- No prices are shown; the framework is described as open source and installed as npm packages.
- Runs on
- CLI
Strengths and trade-offs
Strengths
- One document renders in React, Vue 3 and React Native
- Static validator, 17 lint rules and 6 auto-fixes, runs without an LLM
- Open source, 12 published npm packages and published model weights
- Benchmark publishes all 1107 raw generations for re-scoring
Trade-offs
- Ten fixed component types; anything else needs a host-registered custom type
- The system prompt costs 5,910 tokens on every request
- Renderers are limited to React, Vue 3 and React Native
- The cross-format benchmark is designed, run and published by the vendor

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
