I built Greypaint after getting frustrated with how Mac app updaters still feel like technical utilities from years ago.

Most of them work, but the experience is often cluttered: unclear update states, scattered sources, confusing errors, and no obvious way to know what is happening during an update.

I'm Abner, solo developer in Brazil. Fieldhand gives you a shell in the browser, health data and fleet commands for Linux devices already in the field: kiosks, signage, lockers, gateways on 4G.

Those devices sit behind CGNAT and customer firewalls, so nothing can connect in. The agent is one static Go binary that dials a single WebSocket over TLS on 443. You install it on the OS that's already there, no reflash.

Today I'm launching JAMP! An agentic analytics tool, that is extremely lightweight, cookie-free, and has a generous free tier!
We do Analytics, Error Tracking, Uptime, Performance, and more. Basically an all-in-one monitoring suite for your website, so you can tell exactly what users are doing on your website, where they've come from, and where they are dropping off.
Our biggest differentiator? JAMP is built for Agentic web development. You can connect to our MCP server and pipe all your site's data directly to your AI agent.
Here s how it works: An API fails to one of your users. JAMP collects the error in real-time and alerts you via Email/Discord/Slack. You then ask your AI agent to retrieve the stack trace and the exact sequence of user actions leading up to the crash, allowing the agent to deliver a precise, immediate fix.
Giving you faster debugging, faster development times, and insights for you to make business decisions
We're giving out free Pro for life if you can give us feedback!
If you have any questions, feel free to comment below
Cheers

I run a small web design agency, and for years our cold outreach looked like everyone else's. Reply rates were close to zero.

So we tried something different: before writing to a company, we checked their website and opened the email with one specific, real issue we found.

Here's what one of those first emails looked like:

Hi my name is Sokrates and i have been building Kervyra for some time now. It is an AI agent testing tool with features such as version comparison and test runs. I am looking for testers and early users to test the project and provide feedback

I recently launched Oratii, an AI-powered platform to help people practice speaking, prepare for interviews, and build communication confidence.

The biggest challenge isn't building the product. It's finding the right users, getting honest feedback, and understanding what makes them come back.

I'm curious how other makers approached this stage.

What helped you turn your first visitors into active users?

I am launching FirstFile here on PH tomorrow (Wed 28th), It would be amazing to get some support on the day.
I built this purely to solve my own issue but realised it was helping many friends and family that were starting businesses too.
In a nutshell, I pull new companies from companies house, enrich the data with an absolute plethora of additional source data (local councils, vehicle licensing etc) then using many AI models and techniques, clean, score and present the data for outreach.
Super useful for finding new businesses that are ready and motivated to buy (websites, accountants etc)

Hey everyone!

After a long time building in public, I just launched VIBES PLAN today.

What it does: A trip planner for vibes lovers

Why I built it: Plan trips by how you want to feel, not just where to go

Hi guys, just getting into the startup world. I know my website isn't great but would love to hear any and all feedback and advice! My dms are open and looking forward to learning more and getting more into this space.
