Building Bloomberry - an alternative to Builtwith. While the latter focuses on frontend tech, I cover almost every SaaS product category. Want to know companies that use Microsoft Dynamics or Zoom? You can with Bloomberry, but not with Builtwith.

#252Mostly decentralized/federated crypto stuff.
1. COCKTAIL-DKG - A distributed key generation protocol for FROST, based on ChillDKG (but generalized to more elliptic curve groups) -- https://github.com/C2SP/C2SP/issues/159
2. FREEON (Threshold signing tool for open source development teams) -- https://github.com/soatok/freeon
3. A reference implementation for the specification I wrote last year for federated Key Transparency, so that the Fediverse can build end-to-end encryption (E2EE) with stronger, less-centralized notion of trust than TOFU -- https://github.com/fedi-e2ee/public-key-directory-specificat...
I wrote a blog post about a lot of this work (and my other side projects): https://soatok.blog/2025/08/27/its-a-cold-day-in-developer-h...
And for the overall ActivityPub E2EE work: https://soatok.blog/category/technology/open-source/fedivers...

#253I am building an Options: At-the-Money Premiums tracker to help me view all the options premiums on one screen. Here is the app: https://apps.apple.com/us/app/options-at-the-money-premiums/... Launched on Reddit last week: https://www.reddit.com/r/Optionswheel/comments/1nlelbp/comme... If you guys trade options (selling CSP and CC), I would love to hear your feedback.
Where do you get the data?

#254I am creating a webapp to let screenwriters collaborate when writing their scripts. I have several friends in this industry and their tooling is either expensive, not localized for their market or straight away bad (I've seen terrible dataloss). I got some inspiration from linear and am building it on top of ruby on rails with CRDTs.
How is this different than using Google docs or something ?

#255I'm working on an AI thumbnail/graphics maker using the various image models.
You just upload a picture and pick a design type and it generates a thumbnail for you. Got good feedback last time I posted, steadily and slowly growing now.

#256For the past ten months I've been working on a way to transmit and receive around 10 kilobytes halfway across town. I've blown through government grants totaling in the hundreds of millions of dollars but it seems this is an unsolvable problem.
Ha ha ha.
Funny joke it seems

#257Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.

#258I’m building a daily word puzzle game with a twist! In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword. You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got. I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every da…
Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once.
That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.

#259I have been prototyping a local-only social media manager initially targeting the game development community. I am sick of all the subscription only platforms such as buffer, hootsuite etc.
Initially I have been looking at Mastodon and Bluesky since they have sane APIs.
The plan is to make it so that you can sync your data folder either manually (e.g. dropbox, or sneakernet if you want) or a via a basic cheap data plan.
