The open sky of India,
one coordinate at a time.
A whole-sky view for people, and shared infrastructure for anyone building on top of it.
Why mugilu
For years, people across India have made the sky legible one piece at a time: a map of one city's air, a thread about a heatwave, a chart of last year's monsoon. Brilliant work, but scattered, and easy to lose by the next season.
Sathya Sankaran wanted to stop starting from scratch each time: to pull the whole sky together into one view, every hazard over any point in India, and then hand that out as infrastructure, so the next map, story or alert doesn't have to begin from nothing.
That is mugilu.
For people
Type a place. See what the sky is doing to you right now: air, heat (and how survivable it really is), rain, sun and dust, alongside any official warning over that spot. Then one plain line, the single worst thing for you, whether you have asthma, work outdoors, or are minding a child or an older parent. No sign-up, no jargon.
Build on it
mugilu is meant to be built on, not just looked at. Every reading is also open, machine-readable data, so you can put the whole sky behind your own map, story, dashboard or alert, and spend your time on the part that matters: the telling, and the action.
Today, every page has a JSON and a Markdown twin. Next: a documented API and an MCP server, so apps and AI assistants can ask "what is the sky doing here?" directly. This section will grow as those land.
Where it comes from
mugilu owns no sensors and runs no forecasts. It stands on others' work and credits them: CPCB and OpenAQ for air, Open-Meteo for weather, NDMA / IMD (via SACHET) for warnings, and bharatlas for the map of India. The code is open under the MIT licence; the data keeps each source's own terms.
Why it's free
The sky over you is a commons. Knowing it shouldn't cost money or sit locked inside someone's app. mugilu is non-commercial, for good, the third in a small set of public tools alongside bharatlas and mdshare.
