Once a month. Written by engineers.

The post that did the most work in our drafts that month, the one production note worth your time, and what we shipped. No sponsor slots, no newsletter swap, no growth hacking. Unsubscribe in one click.

What you get

Three things, that’s it.

A short letter, sent on the second Wednesday of the month. Plain text where it matters, code blocks where it helps. Most issues read in under six minutes.

01 / FEATURE

One long-form post

The piece our engineers argued about most this month — a production decision, an architecture trade-off, a thing we changed our minds on. Always with a name on it.

02 / FEATURE

One field note

Something small and useful: a config that saved a week, a regulator question we hadn’t seen before, a pattern we’re trying. Two paragraphs, one link.

03 / FEATURE

What we shipped

Three lines on what went into production at clients last month — anonymised where it has to be, named where the client agreed. No vanity metrics.

The agreement

One letter, one click.

The whole deal, written down. No legalese.

We send one letter a month. We’ve never sent two.
We never share, sell or rent the list. The list lives on a server we operate.
We don’t run open-tracking pixels. We can’t tell you opened it.
Unsubscribe is a one-click link in every issue. It works on the first click.
If we ever change any of the above, we’ll tell you in the letter before we do.
