Hey everyone I'm Stan Cosmin, a former competitive athlete turned solo dev.

Here's the problem I couldn't let go of:

Hey Product Hunt community! I wanted to share two tools I've been working on. Both share a common philosophy: you should only pay for what you actually use, and privacy matters. --- **Toolknit** toolknit.com

If you've ever built a scraper that worked perfectly in dev and then got blocked or CAPTCHA'd the moment it hit production, you already know the pain. You switch providers, tweak headers, slow down the rate and still, somewhere around request 10,000, everything falls apart.

The frustrating part? The IPs weren't even bad. The provider looked solid. But something in your stack was screaming "bot" before the target site even read your first header.

After spending way too many late nights debugging this across multiple projects, here are four things that actually moved the needle for us.

1. Stop treating rotation as a timer.

Hi PH, M lodie here, PM at GetMint
Quick one from me, because these threads are always the most interesting part of the launch.

We're building GetMint, which shows brands how they show up when someone asks ChatGPT or Perplexity about their category, who gets recommended instead of them, and what to actually fix. The tricky part is that AI answers aren't stable, so the real challenge is turning that noise into something a marketer can trust and act on.

Now tell me about you: what are you building, who's it for, and what's the hardest part you're solving right now?

I often copy AI responses (Google AI Search) and paste into my notes keeper app on my Android smartphone. The problem is that its format is not good and I have to modify them many times before they become good for reading. That comes to my idea by making a notes keeper for AI responses which consider AI responses as notes, storing & managing them.

I will launch my new service on 04 Aug 2026. Fast eyes on new service is on this video:

Hello everyone! I hope u guys okay

so, I saw the other days some small shops and business owner have a problem with fee calculation and i said to myself why not build something that help with it.

I introduce you to https://lebanofee.netlify.app/

it helps with everyday transaction and many more!! Feel free and tell me what to add I will hear everyone in the comment.

Hey everyone,

I m Jon Shaivitz, a filmmaker who just launched a new platform called Pitcheroo.

Hey everyone Jada here, founder of NextLevel Digital Store

After months of building, I just launched nextleveldigital.store a digital products shop stocked with over 100 templates, planners, workbooks, and ebooks across 11 categories.

What's inside:

• Business & Entrepreneurship (startup checklists, business plan templates, client onboarding kits)

• Finance (budget spreadsheets, debt payoff trackers, investment planners)

• Productivity (daily planners, habit trackers, time-blocking systems)

• Health & Fitness (workout planners, meal planners, wellness journals)

• Home, Parenting, Creative Writing, Education, Creator Resources, Lifestyle, and a full Ebooks section

Hey Product Hunt solo builder here.

Every multi-agent thing I built ended up with one "manager" object that knew every agent and every step, and an agent harness that was a giant while-loop owning the model call, the tools, the memory, and the approvals. Add a fourth agent and both became the thing that breaks.

So I built Cosmonapse, a distributed agent-to-agent protocol where agents are peers on a shared bus. The model is a nervous system, and the names tell you where logic goes: Neuron thinks (your agent, a pure function), Axon sends, Dendrite reacts, Synapse connects (the bus), Engram remembers.

To build harnesses tool calls, memory, human approval, and retries are typed signals and hooks, not lines in a loop. You grow a harness by adding nodes. An orchestrator is optional, and it's the same primitive as a worker. LLM-agnostic too: each neuron runs whatever model it wants.
