How we choose a stack
- 01
Product needs first
Editing workflow, offline use, real-time data or heavy processing decide the architecture — not trends.
- 02
Scalability
Static where possible, server where necessary, with room to grow without a rewrite.
- 03
Security
Mature, well-maintained tools; secrets on the server; encryption where data is sensitive.
- 04
Maintainability
Popular, documented technologies your next developer will know.
