Uxia▲548Hi HN, As PMs (Google, Gopuff, Shiji), my cofounder and I ran hundreds of user tests over the years. And every time it felt broken: It could take 2–5 days just to get enough usable results We spent hours watching recordings to extract a handful of insights “Professional testers” rushed through tasks for pay, creating biased feedback Platforms often started at €10k+ per year, with hidden fees on top The result: slow iteration cycles, unreliable feedback, and user testing that often felt like a tax rather than a tool. We started asking: what if AI could help? Could synthetic users replicate…

Replicas▲239Hey HN! I'm Connor, creator of Replicas. I'm a heavy Codex/Claude Code user, and I wanted to hand off tasks to agents like I would to an engineer - kick something off before work, let it scaffold while I'm at lunch, even come back to a ready PR. The problem: existing alternatives use workspace VMs that are black boxes. I have no access to any of them - they can't run tests, read logs, or use tools like the Playwright MCP (which I use to verify agents actually fixed what they claim to fix). Replicas gives agents real cloud workspaces where they can: - Run your test suite and read the…

Viberia▲146Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

WarpGrep▲114I review PRs all day and I've basically stopped reading them. Someone opens a 2000-line PR, I scroll, see it's mostly AI-generated React components, leave a comment, merge. I felt bad about it until I realized everyone on my team does the same thing. The problem is diffs are the wrong format. A PR might change how three buttons behave. Staring at green and red lines to understand that is crazy. The core reason we built this is that we feel that products today are built with assumptions from the past. 100x code with the same review systems means 100x human attention. Human attention cannot…

Papercuts▲99Yooo! Papercuts lets you deploy AI agents that flow through your production app like a real user. Just provide a URL and get notified when something breaks. Modern apps are way too complex for brittle selectors. Honestly, I think the only way to feel safe is to test in production with AI agents that actually perceive and navigate like a human.

Hey HN! Sophia here from Glato AI. For the last 3 months, we've been heads down building a cutting-edge short video ads generator. We got the idea because creating UGC shorts for user acquisition is a massive pain. Hiring creators costs $100+ per vid and takes forever. So we thought, why not use AI to automate this? That's where Glato AI comes in - it's one of the most advanced AI workflows we've built. Just feed it a product URL and it'll analyze the details, find related media, understand what's being shown, write a script, create an expressive avatar, lay out each scene with b-roll and…

Hey everyone. My cofounder and I are open sourcing Persona.js (https://www.persona-chat.dev/). It's a VanillaJS library that helps anyone build agentic experiences on the web, without a framework dependency, and full WebMCP support So, why'd we do this? 1) We're super fans of the web and the browser can do a ton today 2) We've seen AI builds be way overly complex because the FE requires a large project within an existing app OR the site wasn't using a framework to begin with If you've been a part of huge apps with multiple frameworks inside them, or work inside CMS /…

Hi HN, I've been using Claude to generate landing pages and it's a huge time-saver. But, it's hard to go from Artifact -> Published website. That's where Artifact Ninja comes in. How it works: 1. Click "Copy" above your artifact in Claude.ai and paste into Artifact.Ninja 2. We'll generate a static webpage without any Claude branding 3. Use your registrar's "masked forwarding" feature to connect a custom domain Artifact Ninja is a quick utility I needed for my own purposes. It's cheap to host (Cloudflare worker + D1), so it's free! Hope it helps.
