2026, in review.

A year of shipping, breaking, and fixing things in the open. Here's what actually happened, not just the parts that went well.

Highlights

Three things worth calling out.

The full write-ups are linked from each post — this is the short version.

01

Tideline went offline-first

The biggest architecture change of the year — councils with patchy internet during a storm now have the whole map cached locally.

  • Full offline map cache shipped in v4
  • Deployed to 5 new coastal councils
  • 72-hour surge forecasting added

02

Coldwatch crossed five countries

Sensor cost came down, deployment count went up. The SMS-only approach kept working exactly as intended.

  • Sensor cost dropped under $9
  • Now live in five countries
  • Alert latency down to under 3 minutes

03

Commons hit 60 organisations

What started as an internal tool for our own field partners became the thing small NGOs actually asked for by name.

  • 60+ organisations hosted
  • Zero paid tiers added — still free, still exportable
  • Full data export shipped for every org

What we got wrong

Tideline's first offline cache implementation silently dropped gauge updates older than 24 hours — a council found it during a real storm, not a test. Fixed in v4.0.2, and it's now part of the release checklist for every product.
