I've built three rental marketplaces from scratch. The painful parts were always the same — real-time messaging that actually works (read receipts, unread counts, email fallback), reservation systems with availability calendars and conflict detection, mutual review systems, and the endless admin panel.

Third time around I stopped and extracted everything into a single boilerplate. The key design decision was making it config-driven — nine feature flags, TypeScript config files for pricing (hourly/daily/weekly/monthly), categories, theme, emails. Flip a flag and the entire feature disappears cleanly, including nav links, context providers, and API routes.

Stack: Next.js 15 App Router, Tailwind v4, Prisma + PostgreSQL, Socket.io, Cloudflare R2. Nothing exotic — any Next.js developer can read the codebase in an afternoon.

Selling it as a one-time purchase. Happy to talk about the architecture or any of the trade-offs I made.

The magic moment is the install. Paste "Follow the instructions at reflectt.ai/bootstrap" into Claude or ChatGPT. It reads the guide, runs the install, and in ~5 minutes you have a coordination server with a task board, shared chat, review gates, and heartbeat loop that multiple agents can join.

We run 9 AI agents on this (engineering, design, growth, ops) and use it ourselves to build it. This week we shipped GET /activity -- a unified feed across tasks/chat/presence/reflections so agents can catch up asynchronously without status-pinging each other.

The core problem: parallel agents without coordination step on each other state. This gives them explicit task ownership, a review process, and a shared memory layer.

Free to self-host: npx reflectt-node. Cloud dashboard at app.reflectt.ai. Curious what others have built for multi-agent coordination -- what has worked?

Hi HN! I built CodeTrackr, an open-source, privacy-first alternative to WakaTime.

It tracks coding activity and provides real-time analytics, global leaderboards, and a plugin system. The goal is to give developers useful productivity insights while keeping full ownership of their data.

Key features: - WakaTime-compatible API (works with existing editor extensions) - Real-time dashboard using WebSockets - Global and language leaderboards - Self-hostable (Docker included) - Plugin system using JavaScript snippets - GitHub and GitLab login

Stack: Rust + Axum + PostgreSQL + Redis + Vanilla JS

Repository: https://github.com/livrasand/CodeTrackr

I would really appreciate feedback, especially regarding: - security - architecture - potential areas for improvement

If you're interested, you're also welcome to build plugins for the plugin store or create IDE extensions for your favorite editors.

Thanks for taking a look!

PS: I used ChatGPT to translate this; my native language is Spanish, and my English is limited.

Hi HN,

I built openEHR-CLI, an open source command line tool to work with openEHR artifacts (archetypes, templates, etc.).

The idea was to make it easier to automate tasks that usually require GUI tools, such as validating templates or processing openEHR resources in scripts and CI pipelines.

One interesting feature is that the CLI also exposes an MCP (Model Context Protocol) server. This allows the tool to be used by AI clients that support MCP (Claude Desktop, Cursor, etc.), so AI assistants can interact with openEHR artifacts programmatically.

Examples of things it can be used for:

- validating templates and artifacts

- inspecting openEHR models

- automating checks in CI pipelines

- exposing openEHR tooling to AI assistants through MCP

The project is open source and feedback is welcome.

I'm building a small experiment called Tasda.

The idea: places have their own AI and you can talk to them while exploring a city.

I'm opening a small Android beta and looking for around 10–20 curious testers.

We're on the Women's Day Sale!

To celebrate it, we are conducting a playtest for Shop Crush. Sign up if you are interested. We are preparing a game demo and would be more than happy to have you try it.

You can sign up for the paytest on our Steam Page.

I'm autistic and ADHD, and I kept running into the same wall with AI tools- not knowing how to prompt them in a way that matched how my brain actually works. I'd have a real idea or need but couldn't get the output to reflect it. So I built BottomUp.

It's a free, no-login tool that walks you through a structured process to clarify your thinking before you prompt an AI. Instead of starting with a blank box, you answer a few focused questions and it builds the prompt from the bottom up — hence the name.

It's built especially for neurodivergent people, but honestly anyone who gets frustrated staring at a blank prompt field might find it useful.

No account needed, runs in the browser: https://www.bottomuptool.com

Would love feedback — especially from anyone who's struggled with the "I know what I want but can't explain it to the AI" problem.
