Meltbox
Easy to try even without an account! Would love all feedback. Hey all, I'm building Meltbox as a better human in the loop system. It's a way to centralize all of the decisions you need to make into context-rich briefs in a system built for fast human review. [Why] Something major changed recently. Agents have gotten even better and even faster at building apps / sites / dashboards / etc... and that's changed my development workflow in a major way. I often have my agents build an entire app/dashboard just to make ONE DECISION. It's no longer just building the product. It's…

What it does
Meltbox is an inbox for context-rich interactive briefs from your agents. Right now when an agent needs you, you end up having to look through terminal scrollback, localhost tabs, and Slack DMs to yourself. In Meltbox, your agents push small interactive pages with all the context you need to make a decision. You triage briefs in a keyboard-fast inbox, tap an answer, and your reply flows straight back to the agent.
Meltbox is the one place your agents reach you. Every brief they push lands in one feed, with the full context to answer fast and keep the work moving.
Every brief they push lands in one feed, with the full context to answer fast and keep the work moving. Meltbox, exactly as it ships. How it works. Three steps from invite to answered decision. Your agents work in the background and push a detailed brief when they need you. Comment and choose options right in the brief. Your agent stays connected and keeps going. The ceiling on how many agents you can run is how well you context-switch. When every agent hands you a context-rich brief, dropping into their work takes seconds, so you can run more of them. New tasks, background loops, multiple machines, multiple harnesses. The bottleneck is how fast you can review what your agents did. Feed it…from meltbox.ai

Shortwave: Enjoy Your Inbox2022 · shortwave.com · ▲224I’m thrilled to finally be able to show everyone what we’ve been working on for the last 2 years. We’re re-inventing the email experience to help you email smarter and faster, so you can get more done, and maybe even actually enjoy your inbox. When we launched Firebase here 10 years ago, HN was tough but fair, and I expect no less this time around! I hope you’ll check out what we’ve built and share your feedback. I’ll be around here all day and am happy to answer any questions. Let us know what you think!
DiracJun 2026 · dirac.app · ▲128It all started 4 months ago during my last startup. Even with barely any traction, I was getting about 20 emails a day. Some from cold randoms, some internal, some from prospects. And I just wasted so much time in my inbox. The current solutions? Superhuman and HEY. Sure they're pretty but the ai is just an after thought. And the tool that was supposed to help me just makes me, my own assistant. So I went and built Dirac. We're launching in 8 hours, https://www.producthunt.com/products/dirac-3?launch=dirac-4
WarpGrepDec 2025 · morphllm.com · ▲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…
We built an AI to review your pull requests2025 · infinitcode.ai · ▲53Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…
Make senders work to get into your inboxJul 2026 · captchainbox.com · ▲44Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
