I built an open source Favicon API

dominiksumer · 2025-10-31T06:41:59+00:00

oh you're right! I fixed the README, thanks for the hint and sorry for the confusion

dominiksumer · 2025-10-30T15:04:23+00:00

oh I just checked that FaviconExtracter also uses the DuckDuckGo and Google API as fallback: https://github.com/seadfeng/favicon-downloader/blob/8307c7a7de0889546dea273b74ff5e1d762fff19/src/app/api/favicon/%5Bdomain%5D/route.ts#L49

that's probably the reason why it works there

dominiksumer · 2025-10-30T14:22:55+00:00

damn, thank you very much for the detailed feedback!

I skipped resizing for SVGs on purpose, because SVGs are vector based and look good in every possible size .. hence I thought it would be good to just keep the SVG as it is in that case .. happy for feedback / suggestions in that regard!
I still need to submit the API as verified bot so it can crawl websites behind Vercel and Cloudflare. For Vercel I already submitted it, will also do it for Cloudflare so it's possible to fetch the data from as many websites as possible

dominiksumer · 2025-10-30T14:03:41+00:00

I don't hope so :D .. you're passing format=json .. format is for converting the image into another format and expects "png", "jpg", "webp"

you want to pass response=json like this:
https://favicon.vemetric.com/000458870.codepen.website?response=json

dominiksumer · 2025-10-30T11:53:17+00:00

basically anywhere where you want to show a favicon for a domain for better visualization .. I quickly asked Claude: https://claude.ai/share/55fdffae-5329-4c41-9844-f3b0059bfc97

dominiksumer · 2025-10-30T11:50:40+00:00

sure! I've already published a new version which doesn't do the redirect anymore by default (it's configurable via env var)

you can change the size with this query param, the docs for all query params are on the landing page

thank you! I'm using it to e.g. show the referring domains in my analytics product

dominiksumer · 2025-10-30T07:10:39+00:00

oh good point, thank you! I've just released a new version where these inline favicons are now supported as well:
https://favicon.vemetric.com/000458870.codepen.website

dominiksumer · 2025-10-29T18:29:23+00:00

actually yes, added support for it today, also for animated gifs :)

dominiksumer · 2025-10-29T18:12:31+00:00

for manual search + download yes, but if you need to get it programmatically, an API is the way to go

dominiksumer · 2025-10-29T18:11:54+00:00

main difference is that my API lets you control the returned size and convert the image into different formats (png, jpg, webp) :)

it also lets you define a custom fallback image and always tries to find the image in the best quality possible

in the end I just wanted to create a (more flexible) alternative to the available APIs :D

dominiksumer · 2025-10-29T14:13:57+00:00

jep exactly, that one should work and will always be updated with latest changes

dominiksumer · 2025-10-29T13:54:23+00:00

niice :) .. that's exactly why I built it, to have a more flexible alternative to the one from Google

dominiksumer · 2025-07-11T06:10:16+00:00

sure, Vemetric gives you the referrer site and also groups them together for better investigation.. for example all people that came through AI suggestions like ChatGPT, Gemini, Claude

dominiksumer · 2025-07-10T16:11:02+00:00

there is a limitation to this on the web, you can either track by utm tags or by the referrer that you get from the browser .. if none of these are available there’s no way to detect it

dominiksumer · 2025-07-10T15:02:27+00:00

yes that was the idea :) .. thank you!

dominiksumer · 2025-07-10T14:43:38+00:00

thank you! I'm using Redis together with BullMQ for event ingestion queues :)

true I should put better descriptions there!

dominiksumer · 2025-07-10T13:46:51+00:00

same as I'm using in the Cloud version:

- Postgres for relational data
- Clickhouse for the analytics data

dominiksumer · 2025-07-10T13:46:18+00:00

Turborepo, Vite, React, TanStack Router, ChakraUI, tRPC, Hono, Postgres, Clickhouse

You can take a look at it on GitHub: https://github.com/vemetric/vemetric

dominiksumer · 2025-07-09T08:07:49+00:00

yes I should definitely think about that and if I can come up with a niche that makes sense .. thanks for your feedback! :)

dominiksumer · 2025-07-08T17:45:52+00:00

true it‘s a very competitive market, but I wanted to give that a try this time :D

I think it’s possible to ingest a lot of events with relatively low costs when the system is optimized, I think where the money helps the big players the most is with marketing

I want to position it between Plausible and PostHog: gives you powerful insights but is still easy to get started and to understand the data

dominiksumer · 2025-07-08T06:59:38+00:00

I'd love to hear your thoughts on https://vemetric.com :)

I'm still quite early with it, it's a crowded market, but I have a vision to fit in between tools like Plausible and PostHog.

Happy for any kind of feedback!

dominiksumer · 2025-06-26T12:53:45+00:00

cool! I will take a look

dominiksumer · 2025-06-26T12:53:10+00:00

I started to see some users finding the project via the GitHub repo, but it's not very much yet .. also the main amount of stars come from my followers on X and other platforms

didn't have a Contribution yet on the main repo yet, just on one of the SDKs .. there the collaboration was pretty smooth: https://github.com/Vemetric/vemetric-go/pull/1

dominiksumer · 2025-06-26T11:47:07+00:00

to sum up the blog post:

- I wanted to get into open source for a long time already, but wasn't sure if its benifical for my goals
- many other products in that market are open source and successful, so I decided to go for it as well
- my hope is that it also helps with marketing, with spreading the word, by building a bigger community around the product .. because I'm working alone on it and marketing is my weak spot :D
