Umbra
OpenAI-compatible API for models nobody else hosts
What this is
An OpenAI/Anthropic-compatible API where Apple Silicon Mac owners host open-weight Hugging Face models for pay-per-token access. Built for developers who want hosted access to niche open models without renting a GPU.
Our one-line summary — not the founder’s tagline.
- How it works
- An OpenAI- and Anthropic-compatible API endpoint where Apple Silicon Mac owners host approved open-weight Hugging Face GGUF models; you swap your base_url, keep your existing client, and pay per token.
- What's different
- Gives hosted API access to open-weight models that otherwise have no hosted API, without renting a GPU yourself.
- Pricing
- Pay per token.
- Best for
- Developers who want hosted access to niche open-weight models without running their own GPU or leaving a Mac on overnight.
- Watch out
- Described by its maker as 'my experiment' — inference runs on community-hosted Apple Silicon Macs rather than dedicated infrastructure.

Dev. Launched 13d ago on Product Hunt, picking up 6 votes. Today, it's been quiet for 9 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?”

Beyan değil kanıt: founder “çalışıyoruz” diye post atabilir, ama sevk ettiyse izi kalır. ⚠️ Kaydı olmayan ürün “sevk etmedi” demek değildir — o üründe izleyecek bir kaynağımız yok demektir.
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 6 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 1 hareket bu listede yok — toplam 13 olay var. 1 quiet day in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
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 useful open-weight models still don’t have a hosted API. You either rent a GPU, leave a Mac running overnight, or send prompts somewhere that can read them. Umbra is my experiment: an OpenAI-compatible endpoint (Anthropic-compatible too) where Apple Silicon owners host public Hugging Face GGUFs they approve. You swap base_url, keep your existing client, pay per token. Try it: https://tryumbra.dev Quickstart: https://tryumbra.dev/docs/quickstart Host a Mac: https://tryumbra.dev/setup

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.
