Supapool – a Supabase per coding agent in ~400 ms
hi HN, I built supapool.io, an ephemeral full copy of supabase's services that you can spin up in ~400 ms (Auth, postgres, storage, realtime). so if you run multiple coding agents in parallel in different worktrees, they can now have their own copy of supabase without making changes that conflict with eachother. > why not use supabase docker locally? when I run 3-4 instances locally, my macbook gets hot and sometimes freezes. > why not use supabase branches? branches take minutes to setup, and are designed for persistence. this is expensive, and for a dev environment, it is too slow. > why…

In plain words
Supapool provides ephemeral, isolated copies of Supabase services—including Auth, PostgreSQL, storage, and realtime—that spin up in approximately 400 milliseconds. It is designed for developers and AI coding agents running parallel instances in different worktrees, allowing each to operate on its own database copy without conflicts. Unlike local Docker setups that consume significant system resources or Supabase branches that require minutes to initialize, Supapool offers rapid provisioning for temporary development environments while maintaining real database behavior for accurate testing and migrations.

Full, isolated Supabase instances for coding agents in 1 second.
Give each agent a full, isolated Supabase instance in 1 second, with Postgres, Auth, and Storage. Run migrations and database operations against the real stack, not mocks. npx @supapool/cli run -- npm run dev Wrap any command. Supapool leases a clean instance, injects its credentials, keeps it alive, and releases it when the command exits. npx @supapool/cli login npx @supapool/cli run -- <command> login opens GitHub sign-in and saves an API key to ~/.config/supapool/config.json . run does the same sign-in on first use, so most people never run login directly. run acquires a clean instance, applies every .sql file in supabase/migrations in filename order, starts your command with the…from supapool.io

Supavisor – a Postgres connection pooler written in Elixir2023 · github.com · ▲149hey hn, supabase ceo here this is a postgres connection pooler. it’s similar to pgbouncer, but built with Elixir and specifically designed for multi-tenancy. it’s still under development, but it’s at a stage where we can gather a feedback from the community and you can try it yourself. we aren’t using this in production yet, but aiming to deploy it for a subset of databases in the next 2 months. We have the following benchmarks (details in the readme): - Elixir Cluster maintaining 400 connections to a single Postgres database - 1_000_000 clients connecting to the Elixir cluster - Sending…

Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir/Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files.…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
