> A map of 467,988 GitHub repositories (two sit close together when the same people starred them), the building blocks of software from data origination to embedded electronics, the white space between them that few people combine yet, and assessed ideas for what to build. Static JSON, no key, no rate limit beyond your host's.

## Use the data

Data as of 2026-10-28 (build v2026-10-28-7). Every JSON file carries an `_attribution` object with the details above.

- Find a repository: lower-case its owner/name, take the first two characters (anything but a-z or 0-9 becomes _), read `/data/v2026-10-28-7/api/repos/<prefix>.json` (1,000+ stars), else `/data/v2026-10-28-7/api/lookup/<prefix>.json`. Example: ollama/ollama -> /data/v2026-10-28-7/api/repos/ol.json.
- Capability: `/data/v2026-10-28-7/api/capabilities/{id}.json`. One building block (147, from data origination to embedded electronics): what it is, what it unlocks, the best repositories, momentum, cited 3/6/12-month projections.
- Country: `/data/v2026-10-28-7/api/countries/{id}.json`. One map country (a community of repositories starred by the same people): name, size, continent, topics, top repositories.
- White space: `/data/v2026-10-28-7/api/white-space.json`. Capability pairs worth combining that few people combine yet, each with a product to build and repositories to start from.
- Ideas: `/data/v2026-10-28-7/api/ideas.json`. Things to build, assessed for usefulness, novelty and feasibility now and in 12 months.
- Trends: `/data/v2026-10-28-7/api/trends.json`. How new stars moved between Software 1.0, 2.0, 3.0 and AI coding, by year, and the fastest-growing capabilities.
- Capability list: `/data/v2026-10-28-7/capabilities.json`. All capabilities with layers, interfaces and share of new stars by year.
- Names: `/data/v2026-10-28-7/names.txt`. Every repository on the map, one owner/name per line; line i = map index i (most-starred first).

- Catalogue: `/data/v2026-10-28-7/api/index.json`; OpenAPI 3.1: `/data/v2026-10-28-7/api/openapi.json`.
- The live build: `/data/current.json` = {"base": "<build>"}; builds never change once written.

## How it was made

Positions and neighbours: co-stars recorded by GH Archive (dense to May 2025, a sample since). Stars over time: GH Archive to May 2025, then GitHub's star history endpoint (exact, for the most active repositories) or calibrated estimates; the share that is exact is in api/trends.json. Labels (kind, paradigm, capability, neighbour relation): Jev, a fast heuristic model. Value judgments (white space verdicts, idea assessments): GPT-6.1 Terra. Projections are labelled as projections.
