mercator
Weather, ocean & elevation data as value-encoded map tiles
What this is
An open-source SDK that serves weather, ocean and elevation data as map tiles with values baked into the pixels, so you can restyle colormaps or switch to contours client-side without refetching. For developers.
Our one-line summary — not the founder’s tagline.
- How it works
- Serves weather, ocean and elevation data as map tiles with the physical values baked directly into the pixels and decoded on the GPU, so you can change colormaps, switch to wind streamlines or contours, or re-scale client-side without refetching.
- What's different
- One open-source SDK works across MapLibre, Mapbox, Leaflet, OpenLayers, deck.gl and React, and the tile format is documented so you can decode it yourself without being locked to their renderer.
- Pricing
- Transparent pricing with a free tier.
- Best for
- Developers building map-based visualizations of weather, ocean or elevation data.

Dev. Launched 15d ago on Product Hunt, picking up 4 votes. Today, it's been quiet for 15 days and the price has started to bleed.
Already bleeding a little every day, and it accelerates the longer it stays quiet.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 4 votes.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
En eski 4 hareket bu listede yok — toplam 16 olay var. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
No names, on purpose — a call is worth what it turns out to be worth, not who made it.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
Most weather and ocean APIs give you a value at a point. mercator gives you the whole grid as map tiles, with the physical values baked into the pixels and decoded on the GPU. So you change colormaps, switch to wind streamlines or contours, or re-scale, client-side, no refetch. One open-source SDK for MapLibre, Mapbox, Leaflet, OpenLayers, deck.gl and React. The tile format is well-documented, so you can decode it yourself and never get locked to our renderer. Transparent pricing, free tier.

The board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
