Claude Code (Opus or Sonnet) via Herdr with probably 4 or 5 things going at once but at different levels of urgency. Mostly I'll be working on one thing (and maybe two git work trees of a project?) and then then have some other research or analytics task going.

We're a non-profit and Anthropic actually has quite nice pricing for teams licenses so I can do most of what I need in a day within the team "Nonprofit Premium" allowances without paying for extra usage.

I have MCPs connecting to Asana (for bug/task tracking) and Looker (for reporting and analytics) but otherwise the setup for each project is just its own GitHub repo and the occasional local skill (eg one that understands common Looker data patterns for our setup or the wacky history of our Archive).

For longer batch tasks or our automated systems we're using various models through Bedrock so I can track it with the rest of our AWS spend and that's been working quite well.

I'm experimenting with Opencode and Openrouter/Bedrock. If Claude Code didn't exist I would think Opencode was a miracle from heaven so it's a nice backup Anthropic pricing gets unweidy.
