What it does
Most startups ship fast and have no QA team, so tests get written late, break often, and quietly get ignored. Blop fixes that. You describe what your app should do in plain English. Blop builds a deep map of your product, tests it like a real user on every deploy, and when something changes and a test breaks, it repairs the test and opens a PR for you to review. The tests stay as real code in your repo. You own them. Nothing locked inside our tool.
Blop is a local-first OpenTelemetry observability CLI. Collect traces and logs, query services, and run deterministic audits with stable JSON output and documented exit codes. Built for coding agents.

DiploiMar 2026 · diploi.com · ▲99After 20+ years in consulting you are entitled to build your own deployment platform, right. So that's what we did. We needed something powerful, supporting all stages from development to production, where new developers can be productive in minutes. Something fun to prototype with, with minimal DevOps but still flexible enough for a wide range of projects. We identified three principles 1. Own your stack - Keep as much of your project inside the platform (also databases, S3) so development will match production and cloning and maintaining and testing, will be easy 2. Infrastructure as code…
Bloop – Answer questions about your code with an LLM agent2023 · github.com · ▲118Hi HN! We launched bloop 10 weeks ago (https://news.ycombinator.com/item?id=35236275) and received a huge amount of feedback (both positive + constructive). We've undertaken a rewrite of the core search framework, which now acts as an LLM agent, significantly improving the number of queries that can be successfully answered. There's a bunch of hype surrounding LLM agents, but we're positive this is one of the first implementations of an agent that can deliver immediate value for engineers working on existing projects, especially larger ones. We'll do a full write up of how the…
I built a tool to get instant test results2022 · github.com · ▲96I got sick of the old software development loop: Change code -> Run tests -> wait -> wait some more -> look at failures. I decided to build a tool that will enable you to: Change code -> look at failures. No wait time, no explicit test running. Under the hood: - Runs the whole test suite and collects code coverage per test. - For each auto file save, analyzes the changes on the tests. - Runs changed tests in the background. - Display results, the loop time from change to test results is approx 250ms. Instead of: code -> alt+tab -> arrow up -> rerun all the tests -> wait ... -> test results…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
