I built ProtoWall (https://protowall.app), an auth and NDA wall that sits in front of your prototype. You invite someone by email, they log in via magic link, sign a versioned NDA, and get reverse proxied through to your app. No SDK, no middleware, no code changes on your end.
Built it because I was tired of the "just password protect it" workaround when sharing early stage work. Passwords get forwarded, and wiring up auth on something you'll throw away is wasted effort. I wanted a paper trail. Who saw what, when they signed, and a way to revoke access instantly.
Free tier gets you 1 project, 5 invites, default NDA template, and a 7 day audit log.
I am building Sensonym (https://sensonym.com), a vocabulary learning app that uses phone sensors (gyroscope, camera, mic, accelerometer) to tie physical interactions to words. For example, you tilt your phone like a glass to learn "drink", shake your phone to learn "earthquake", charge it to learn "eat". The idea is that these associations help improve recall.
I've just launched it on iOS and Android in Germany with support for 10 languages. Happy to receive any feedback
https://www.salaryconfidential.com which allows you to run private small-size peer compensation surveys without leaking identity (anonymous forms aren't that anonymous when you pick up any context. You can get incredibly niche, as long as a survey peer group is at least 4 people. And hopefully, this sets you up to negotiate hard based in real-life evidence, not broad ranges from Glassdoor
We use data models and release rules borrowed from k-anonymity techniques, batched releases and privacy pass cryptographic tokens to create super safe surveys, and everyone who participates as an invite peer gains access to the same full-fat report.
Our form supports specific benefits extension by geography, an extended equity compensation set of questions for packages where equity is significant; and performance pay questions for groups (like sales, execs) where performance pay is also a significant part of the package
Also, we make it easy to explore pay gaps (gender, ethnicity, gender identity, whatever it is) because you can run several peer groups under one poll. no person gets tagged but you do know which respondent was in which peer group - so you can keep context in view (but size needs to be at least 4) but also have a broader view by rolling up results.
I'm building free immigration software for DIY applicants [1]
It's a free USCIS form-filling web-app(no Adobe required). USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, fields break, and getting the signature is hard.
So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.
I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [2]
So, a free (and local-only) version might be a good alternative
Just finished building a side project that utilizes Android's captive portals, The main idea was an offline space for strangers who would randomly connect to an open wifi network. From there their device would open the captive portal webview in full screen, and from there they can explore the platform.
I used a unique modern matrix and polished everything with another project I built which's a deterministic picture generator used to let people interact with something interesting, already using it to produce their default profile picture using their id as the seed.
It meant to run on raspberry pi and I already built an img for the first release.
I’ve been working on an open-source tool to help visualize JavaScript/TypeScript codebases (React, Next.js, Node.js).
The core idea is building a dependency graph at the function/component level and exploring relationships across the codebase.
One feature that turned out to be particularly useful is what I think of as “blast radius”, If you change a function or component, what other parts of the system are affected?
This has been especially helpful when thinking about PR reviews, not just what changed, but what the change might impact indirectly.
It’s still early, and I am working on the cloud version which will include LLM interface to interact with graph and other team collaboration feature and github connection but I’d really appreciate feedback from others who might find this tool useful, and I invite anyone and everyone to contribute to the open source github repo.
First skills matrix software on the market that actually helps you build a process that supports people growth and allows managers to manage without heavy, and expensive HR tools. Main page: https://matricsy.com and just started working on PL version: https://matryca-kompetencji.pl/
Something like Windows Task Manager but it also works in Linux, monitors Docker containers, provides logging, and spins up web servers. It’s web servers serve http and web sockets from the same port and includes streaming proxies.
I’m building DataJelly.com — a visibility layer for AI-built and JS-heavy sites.
A lot of tools like Lovable and Bolt generate apps that look great but don’t expose content well to search or AI crawlers. The impact is lower search ranking, fewer AI citations, and broken social links.
We fix all of that by returning fully rendered HTML to SEO bots and clean Markdown to AI crawlers so they can actually understand the content. We also fix the Social Sharing broken links with custom HTML generated just for sharing your links on social.
My wife and I continue to work on Uruky, a EU-based Kagi and Google Search alternative [1].
Since last month we finally got our production API Key for EUSP/STAAN (it was certainly the slowest and most complicated search provider to adopt, so far), and that brought us to 5 search providers you can choose from and sort as you prefer.
We already have got over 40 paying customers (excluding family and friends, we’re guessing these paying customers came from some privacy listings and HN comments) and have exited beta last month!
Customers seem to really enjoy the simple UI (search can be used without JS) and search personalization (from choosing the providers to the domain boosting and exclusion). We also have hashbangs (like "!g", "!d", or “!e”) when something doesn’t quite give you what you’d expect, though.
You can see the main differences between Kagi and Uruky in the linked page, but one huge difference is that with Uruky, after being a paying customer for 12 months, you get a copy of the source code!
One thing we’re struggling with is outreach because we want to do it ethically, and it’s hard to find communities or places to sponsor which are privacy-focused and don’t require €5k+ deals. Ideas are welcome!
Because of bots there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a couple of days for free, reach out with your account number and we’ll set that up!
Thanks.
P.S.: Because people have asked before, our tech stack is intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such), using Deno in the backend (for easier TypeScript), PostgreSQL for the DB, and Docker for easier deploying.
P.P.S.: Because this has been also brought up before, the name has no special meaning but we read it like "Euro-key" in English. Names are hard, and we’re aware it can remind people of Uruk and Uruk-hai. That’s OK.
P.P.P.S.: Another frequent question here is “how does it work?” When you search, we query the first search provider on your list, and if it yields less than X results (only Mojeek really gives us a total count, we have to try + estimate for the others), we try the second, and so on. We then merge the results in a round-robin fashion (first of first, first of second, second of first, second of second, and so on). There’s a bit of more nuanced logic to also properly rank the results with the pin/exclude/raise/lower preferences, because it works differently across providers and not all of them support that, for example.

A whole bunch more work to do around that, but I think letting folks drop code in makes more sense than continuously updating the UI.

Not me but good friend of mine is building https://onepilotapp.com , genuinely looking for it going live.. me I m testing SEO, unsuccessfuly so far ^^
Mobile first IDE!
I would love to use it, it will certainly help me when I am not able to use my laptop.
Mhm. Great!
Btw. Nice to meet you.
So what did you learn in SEO? I generally don't have much knowledge about it.
