This is the first post on Engineering at Theo — a place for the team to share decisions, launches, and tutorials from building the full Theo stack.
What you'll read here
We're committing to roughly weekly posts in four shapes:
- Launch narratives — the story behind a feature we just shipped, including what we rejected and why.
- Engineering decisions — postmortems, architecture trade-offs, deep dives.
- Tutorials — how to ship a real thing with Theo, end-to-end.
- Comparisons — honest reads of how Theo lines up against adjacent tools.
Why now
The product surface is in place: TheoCode codes it, TheoKit shapes the app, TheoCloud ships it. The team is shipping weekly. Writing here is how we close the loop with the people using Theo.
The 30-second TheoCloud demo
