The neki router shares no code with Postgres.

However we have a whole team working to improve Postgres and we always prefer to contribute those efforts to the Postgres community.

Correct.

The PlanetScale team spent years improving Vitess with lessons learned from many different high scale customer workloads. We continue to invest in and improve Vitess. It's a substantial and growing part of our business.

Vitess today is not the Vitess of 2021. About 70% of the current codebase was written in the last five years, based on lessons we learned running it at scale.

Neki is built for Postgres from the ground up, by the engineers who did that work.

On the Multigres comparison, I'll admit we get a bit salty, mostly because "Vitess for Postgres" invites the comparison. But to date there's no public evidence of a working sharding implementation in Multigres. Their sharding design doc landed this week, and it lists cross-shard query planning and resharding execution as explicitly out of scope.

Neki does sharding today, including online resharding that switches traffic without a maintenance window. It isn't open source, but you can spin up a cluster and try it yourself.

Many of the engineers who built Neki also worked on Vitess for years. But it's a ground up new implementation designed to specifically target Postgres.

Once they implement sharding...

Bus ads have been running for a little while now. A few billboards around too.

You can expect to see it in early 2026 for both Metal and EBS backed databases.

I can't really help with what you're specifically looking for, but I'm pretty sure my grandfather worked on these as an engineer. He retired from Boeing in 1985. Died almost 20 years ago.

This is on macOS. That is hello.py compiled to wasm with Py2wasm.

Here is a trivial example, also on a M3 Max:

  cat hello.py
  print("Hello, Wasm!")

  time python3 ./hello.py
  Hello, Wasm!

Hertz also had absurd policies like bring the EV back 100% charged. Which is basically impossible unless there is a DC fast charger adjacent to the rental car center.

I wonder if this opens up an opportunity for Bombardier and Embraer to move up market into the 737s space.
