I vibe coded an open-source Go app to back up DBs using Docker labels

Hey HN, I'm excited to share Label Backup, an open-source project I developed. This tool, written in Go, automates backups for databases running in your Docker containers using simple container labels. I built this with vibe coding. How it Works: - You add a few descriptive labels to your containers that run databases you want to back up (e.g., backup.enabled=true, backup.type=postgres, backup.cron="0 2 * * *", backup.conn=..., or backup.type=volume, backup.path=/my/data). - Label Backup, running as a separate container, automatically discovers these, then schedules and performs…

    I built an app to stop that mini heart attack you get when you realize you’ve lost code. It's called Vibe Backup, and it's made just for us. It automatically saves versions of your Vibe Coding projects in the background. Think of it as a simple time machine for your code. It works great with Git—saving a snapshot after each commit—and has a hotkey for those "hold my beer" moments before a big refactor. Restoring is just a click. Key features: Trigger backups instantly with KEYBOARD SHORTCUTS — without leaving your IDE. Set it and FORGET IT — Schedule backups on a flexible timer or…

    Built Vibe Manager after getting tired of agents drifting in large repos. It finds the right files, pulls current docs, then runs multiple model providers in parallel and merges the plans into one so changes land in the correct places. What’s different: – Multi-model planning: run several LLMs in parallel; Vibe merges them into a single, reviewable implementation plan. – File selection: surfaces the few files that matter (respects .gitignore, filters large/binary). – Fresh docs: pulls the latest vendor/framework docs into the plan. – Local-first privacy: your repo stays on your…

    Hi 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…

  • Tapflow 2.0▲1,125

    We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
