Alternatives / Streamlit
Looking for an open source Streamlit alternative? Only one project we verified fits: MDMA, an MIT project that extends Markdown with interactive components. It targets AI-generated documents rather than Python data apps, so it is a different tool, and a very small one.

We looked for open-source tools that build interactive interfaces from simple code. We verified MDMA's license, recent activity, stars, and features in its repository. It does not compare directly with Streamlit. See our methodology for the full criteria.
MDMA, Markdown Document with Mounted Applications, extends Markdown with forms, tables, approval gates, and charts declared in fenced blocks. It has nine component types, a React renderer, a validator with 17 lint rules, a CLI, and an MCP server.
MDMA is aimed at AI chat apps and agent-generated documents, not at turning Python scripts into dashboards. Its React Native renderer is still in progress, and the project has about 70 stars.
MDMA is MIT.
MDMA had commits in October 2026.
Streamlit is itself open source, but teams look elsewhere when they want something other than Python scripts for interactive output. MDMA lets LLMs produce structured interfaces in Markdown instead of plain text.
MDMA, Markdown Document with Mounted Applications, is an MIT project that extends Markdown with interactive components such as forms, tables, approval gates, and charts declared in fenced blocks, so LLMs can produce structured UI. It has a React renderer, a validator, a CLI, and an MCP server. It differs from Streamlit, which turns Python scripts into apps.
Pricing: Free and open source.
