RAG-as-a-service

gooood morning legends! Welcome back to another bumper edition of the Leaderboard. In today's email, we're diving into a RAG-as-a-service tool, a platform for devs to finally finish their portfolio, a GitHub-style app but for habit-tracking, and an AMA with serial founder legend Pieter Levels about what it will take to save Europe's startup scene.

Supavec is an open-source platform for building Retrieval-Augmented Generation (RAG) apps, letting developers connect AI models to their own data. It supports small and large-scale projects, runs on Supabase and Next.js, and can be self-hosted or used in the cloud—giving full control over data without vendor lock-in.

🔥 Our Take: Most RAG tools tie you to a closed system, which makes scaling or customizing a pain. Supavec skips the proprietary nonsense, offering an open-source option that developers actually control. If it’s as flexible as it claims, it could be a solid alternative for anyone tired of AI tools that come with strings attached.

Devlopea 2.0 gives developers a place to actually show off their work without duct-taping together a LinkedIn, GitHub, and some half-finished personal site from 2017. It organizes projects, certifications, and experience in a way that makes sense—now with Next.js under the hood for better speed and visibility. Less scattered links, more “look at this cool thing I built.”

🔥 Our Take: Developer portfolios are usually a mess of GitHub repos, outdated personal blogs, and a Twitter bio that says “thoughts are my own.” Devlopea wants to clean that up, but the real question is whether devs will ditch their existing patchwork for something new. If it catches on,

CLY Pixel is like GitHub’s contribution graph, but for your life. Each day you log habits, moods, or activities, and over time, it builds a visual mosaic of your routines. Instead of just tracking streaks, it turns self-reflection into something you can actually see.

🔥 Our Take: Most habit trackers feel like a guilt trip when you miss a day. Turning it into a colorful, data-driven snapshot makes it more about patterns than perfection. Whether it actually helps build better habits or just looks cool is another question—but at least it makes self-tracking less boring.

You’ve seen the memes—while the US and China push AI forward, Europe drowns in paperwork. Pieter Levels knows this struggle firsthand. As a digital nomad and indie hacker, he built businesses without relying on VC, only to watch EU regulations make it harder for startups to thrive.

His project, eu/acc, is pushing for fewer restrictions and more innovation—and policymakers are starting to listen. Now he’s hosting an AMA to talk about what’s next. Got thoughts?
