Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP https://bit.ly/4eSDW7K

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP I originally made Serene Bach in the 2000s as a weblog engine written in Perl CGI. I rebuilt it from scratch in Go as a single binary that can run either as a CGI program or as a normal HTTP server. I know CGI is generally considered legacy technology now, but I still rely on it for shared hosting. In this version, I added Markdown support, a responsive default theme, Open Graph image generation, and static output generation. It is still in beta, but the repository includes a Docker image published on GHCR, documentation, and a local quick start. I'd appreciate feedback from anyone interested in small self-hosted publishing tools, especially if you still care about shared hosting or CGI-style deployment. https://bit.ly/4dzexgV May 17, 2026 at 04:47AM

Show HN: Codiff, a local diff review tool https://bit.ly/4ucQT0L

Show HN: Codiff, a local diff review tool Nowadays I review a lot of code locally that was written by llms. I used to review my own code using git + delta. It started to feel limiting with the amount of code written by llms. When looking at a large diff on Friday I pointed an llm at diffs.com and trees.software and told it to build an app. It only took 16 minutes, is extremely fast for large diffs, beautiful and minimal. Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm. I will be using Codiff a lot, and can finally review the large diff from Friday that led me to build this If you like it, fork it! https://bit.ly/4wyBFoj May 17, 2026 at 06:30AM

Show HN: SwarmWright, structured multi-agent AI defined in markdowns https://bit.ly/4dnS6Lv

Show HN: SwarmWright, structured multi-agent AI defined in markdowns I had a bunch of custom AI pipelines and a growing folder of markdown files and Python scripts holding it together. Built this to give that chaos some structure. Agents are markdown files, topology is a JSON file the runtime enforces hard. The agents are still fully autonomous: they make their own decisions, but the graph they operate in isn't. You declare who can call whom upfront and the runtime holds that line. No auth yet, fine if you don't expose the port, i guess. Two Docker commands to run it. https://bit.ly/42E7NcB May 15, 2026 at 09:50PM

Show HN: Epiq – Distributed Git based issue tracker TUI https://bit.ly/3RHOUDc

Show HN: Epiq – Distributed Git based issue tracker TUI Issue trackers typically live outside of your workflow, with poor ergonomics. Epiq aims to solve that, bringing issue tracking into your terminal. Multi-user collaboration is achieved via git using user-scoped immutable event logs that converge in memory. Put my all into it. Let me know what you think. https://bit.ly/493GpIL May 16, 2026 at 01:18AM

Show HN: Petri – Drop-in Postgres image that forks a DB per test Rolling it out at work to parallelize 4,257 tests across 5 services. It fixes our tests running in band and DB mocking in API tests. It's a drop-in Postgres image, with a Golang proxy. :5432 is passthrough, :5433 forks the DB per conn (CREATE DATABASE … TEMPLATE …, dropped on disconnect). If you use it, let me know what you like or don't like, so I can make it better. Cheers! https://bit.ly/4dHKdlu May 14, 2026 at 12:32AM

Show HN: HYPD – AI co-pilot for marketers running Google Ads https://bit.ly/4tASBrQ

Show HN: HYPD – AI co-pilot for marketers running Google Ads We've been building HYPD for the last 1 year together with a small team in Berlin. It's an AI co-pilot (chatbot) for PPC freelancers and agencies. It connects to a Google Ads account, then runs audits, performs data analysis from natural language ("why did CAC jump last Tuesday"), generates ad copy grounded in account history and context, and exports reports and datasets. Thesis behind it: just like programming is "solved" but engineering is not, ad-ops and media buying will be solved, but account strategy and human creativity remain the leverage. Background: I founded PubNative (acquired by Verve Group), was Co-CEO at Verve Group, and for the last year we've been "taming" LLMs when working with structured and unstructured data. So far we got more than 200+ agencies and freelancers onboarded. Hard parts so far: (1) data accuracy, (2) understanding the gaps in LLM knowledge of the Google Ads API, (3) adding enough context to make answers fit what professional marketers expect. Free trial + free tier on the site. Happy to enable demo accounts for anyone who wants to test it without connecting their account. https://bit.ly/4eOAQlb May 13, 2026 at 10:09AM

Show HN: I spent $100 in Claude tokens and 1k battles training my AI tank https://bit.ly/3OWimok

Show HN: I spent $100 in Claude tokens and 1k battles training my AI tank Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code. https://bit.ly/4nto7GK May 13, 2026 at 03:20AM

Show HN: NodeDB – High Perfomance Multi-Model Database https://bit.ly/4d5meMY

Show HN: NodeDB – High Perfomance Multi-Model Database Hey HN, I've been working on a multi-model database called NodeDB. Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc). And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of just treating it as KV database, we build specialized engines for the data. Besides that, I want it to be able to support my IOT/edge project, where i need offline sync capabilities (Currentyl still in progress). Will it work? I put it into test. I've been experimenting and researching for a year, creating multiple versions, and then I created NodeDB. Disclaimer: It is still in public beta (as of May 2026), but it really excites me if I can make this db work. And I use AI as assistant for coding and planning. It is nearly impossible to do as a solo developer without any AI assistance. Would love feedback from HN: - Are there specific features or improvements that would make it more useful? If you're interested in experimenting or contributing, the repo is here: GitHub Repo: https://bit.ly/4nlpE1s Looking forward to your thoughts! https://bit.ly/4nlpE1s May 12, 2026 at 12:21AM

Show HN: Safe-install – safer NPM installs with trusted build dependencies https://bit.ly/4nnPzW8

Show HN: Safe-install – safer NPM installs with trusted build dependencies In light of the ongoing npm supply chain compromises, I built safe-install: https://bit.ly/4wpkUvV It brings a couple of protections I wanted from npm but are not built in. Similar to Bun’s trusted dependencies, it lets you disable install scripts by default and define a list of dependencies that are allowed to run build/install scripts: https://bit.ly/4nr62sS It also supports blocking exotic sub-dependencies, similar to pnpm’s `blockExoticSubdeps` setting: https://bit.ly/4wGyKub... I was hoping npm would eventually add something like this, but it does not seem to be happening soon, so I made a small package for it. https://bit.ly/4wpkUvV May 12, 2026 at 01:30AM

Show HN: An addictive phone game about phone addiction I recently prototyped a web game for a nonprofit to highlight the dangers of phone addiction, but unfortunately I ended up making a really addictive game instead. :-\ I'm sharing this here mainly to serve as an indicator of what can be achieved early-2026 by a senior dev working with Opus 4.7 over 2 days using genuinely collaborative prompting. (ie plan->feedback->iterate) Hope it provides some inspiration or entertainment - there's a level editor too - maybe Hacker Newsers could share their favourite creations here? PS: If there's enough demand I'm happy to Open Source this (or DM me) - it's mainly just time restrictions at my end. https://bit.ly/4u2Mg9v May 11, 2026 at 10:39AM
