Is your website throwing 502 errors whenever an external API starts lagging? It is a common engineering grind where slow dependencies choke your server and kill your response times.

Distinguish between workers
If your team works with geospatial data, sooner or later you need a place where maps, layers, users, and edits live together. There are many capable SaaS platforms and proprietary solutions you can deploy on your own infrastructure, but there is another path: self-hosting an open-source Web GIS server.

Everyone benchmarks models. Sonnet beats Haiku on reasoning. Opus beats Sonnet. Haiku is fastest. These things are all true. But benchmarking and deploying are different games. At scale, the difference between Haiku at $0.80/million tokens and Sonnet at $3/million tokens isn't academic. It's $400+ monthly on a mid-size application. The trap is paying for capability you don't actually need because
