Norns
The development ecosystem built for AI authorship.
A flavored stack (Civet, Pug-flavored Svelte 5, SvelteKit) engineered so AI writes applications and automations with dramatically fewer tokens.
Why it matters
Tokens are the new compute.
Every token an AI spends on boilerplate is a token not spent on your logic. Norns compresses the surface of a full-stack app (templates, scripts, wiring) so the same context window holds more of your application, generation runs faster, and costs drop 20–25%.
Denser syntax
Civet scripts and Pug templates express the same Svelte 5 logic in fewer tokens, without losing readability.
Feature-folder runtime
DI, validation and server actions follow one repeatable pattern AI can copy for every new domain.
Built on standards
Svelte 5, SvelteKit 2, Vite, Tailwind 4, valibot. Norns flavors the stack, it doesn't replace it.
Lower cost
Fewer tokens means a smaller bill for every generation: the same AI budget ships 20–25% more application.
The ecosystem
Six repos, one pattern.
norns
MITThe framework: preprocess pipeline, runtime, server actions, auto-imports.
norns-core
MITThe compiler core: Civet + Pug transforms that power the pipeline.
norns-ui
MITUI components, motion primitives and form patterns, shipped as .n source.
norns-app
MITThe starter template: a full runtime demo in ~60 lines you can rewrite in a sitting.
norns-demo
MITSide-by-side comparisons vs vanilla SvelteKit, with LOC and token counts.
norns-mcp
PaidThe licensed MCP server: a concept graph of your code that cuts another 50–75% of tokens.
Norns MCP · Licensed
AI that works with concepts, not files.
Norns MCP is a separate, licensed layer on top of the open-source ecosystem. It builds its own index of your codebase: a graph of the logic concepts inside it and how they connect. AI agents query that graph directly instead of reading files and lines of code, and everything gets cheaper and faster at once.
More token reduction
On top of Norns' 20–25%: the graph serves an agent only the concepts a task touches, never whole files.
Tool interactions
One graph query replaces whole chains of file reads and searches, so agents finish tasks in fewer steps and development speeds up.
Context for your logic
Smaller payloads leave the context window free for actual reasoning. Token, tool and context savings compound into real cost cuts.
License

Built with Norns
AIOSIS AtoZ runs on Norns
Our AI factory automates digital businesses end to end, and every automation and operation it ships is built on Norns and Norns MCP by default. See what the stack looks like at full scale.
