Every culture is different but at PlanetScale we do stuff and then make videos about it.

We did it! Framework Laptop 13 Pro is on TIME's Best Inventions of 2026. This is our third product to list, after the original Framework Laptop in 2021 and Framework Laptop 16 in 2023.

My fav sharding lore is that the term likely comes from an evil wizard. Ultima Online was growing so fast in 1996 that they had to spread players across separate servers. They wanted it to make sense in the story, so the designer dug through the original Ultima games from the 80s. At the end of Ultima I, a wizard traps the world in a crystal that gets shattered. So the story is that each "shard" holds a copy of the world.

Operating a massive fleet of databases comes with many challenges. Kubernetes allows us to do so safely and reliably. Self-healing systems, configuration management, failover, and more across thousands of nodes. @fatih walks through how it all works in our latest blog.

PlanetScale and I just sponsored @dominikh: staticcheck is crucial for every project we build and we are so grateful for your work. Happy holidays from @PlanetScale!

We are bringing this power to Postgres neki.dev/
PlanetScale is a beast. Our largest workload there has 256 shards and 300 TB (!) of data. Queries respond at ~10ms (p99) at peak hours. Just bonkers.

PlanetScale uses Cursor to build PlanetScale, which Cursor then uses to build Cursor, which PlanetScale uses to build PlanetScale, and so on.

We’ve been hard at work building the most scalable and reliable sharding solution for Postgres. A great piece of software deserves a great name and iconography. Say hello to Neki.

We're looking for new Software Engineers at @PlanetScale. Ideally you're a great fit for this role if you enjoy working autonomously, are comfortable collaborating with multiple teams, and have a deep understanding of distributed systems and Go.

The project nobody has seen yet is Nova. Vitess for Postgres. Built from first principles, not using Vitess. We have spent 4 years sharding some of the world's largest databases. Those learnings will inform an architecture bespoke to Postgres. Only PlanetScale can do this.
