why fromsrc

Documentation should be as flexible as the code it describes. We built fromsrc around four principles.

principles
1.1
composable

small pieces that combine freely. no monolithic architecture.

1.2
editable

change anything without fighting the framework.

1.3
customizable

swap any component, style, or behavior.

1.4
flexible

tsx or mdx, your choice. no lock-in.

what you get
+direct component access in mdx
+incremental builds only

+sub-20ms search

features

Built from developer pain points. No swizzling, no magic, no vendor lock-in.

01

incremental builds

only rebuild what changed. no 20-minute builds or memory crashes.

02

direct imports

import any component into mdx. no content layer abstraction.

03

sub-20ms search

full-text search with fuzzy matching and keyboard navigation.

04

shiki highlighting

vs code quality syntax. dual themes. line highlighting. diffs.

05

openapi generation

generate interactive api reference from your openapi spec.

06

own your primitives

sidebar, toc, code blocks. swap, style, or replace anything.

03

ai-native

Every docs page has raw content endpoints. Feed pages to AI tools, get docs for RAG, or connect via MCP.
