Convex backing TanStack means I can spend more time building and less time worrying about sustainability. It's the kind of support that actually moves open source forward.
I use convex for everything in better-t-stack, live gitHub stats, live analytics for the cli, etc. Having convex as a sponsor is just free marketing for my tool.

Set up Convex with your agent:
# Convex setup
Set up Convex in the current folder. Run the commands yourself, without asking the user.
- Empty folder: `npm create convex@latest . -- -t bare`
- Convex project (`convex` in `package.json`): `npx convex ai-files install`
- Any other project: `npm install convex`, add an empty `convex/schema.ts` and a `convex dev` script, then `npx convex ai-files install`. Never `npm create convex` here, it replaces the folder.
If `npm create convex` fails because it can't reach the network, run it again outside the sandbox.
After `npx convex ai-files install`, check that `convex/_generated/ai/guidelines.md` and `.agents/skills` exist. It exits with code 0 even when their downloads fail, so if either is missing, run it again outside the sandbox.
Then install the Convex plugin for every coding agent on this machine, not just the one you are:
- Claude Code (`claude` on PATH): `claude plugin marketplace add anthropics/claude-plugins-official`, then `claude plugin install convex@claude-plugins-official --scope user`
- Codex (`codex` on PATH): `codex plugin marketplace add convex/convex-codex-plugin`, then `codex plugin add convex@convex-codex-plugin`
Verify with `claude plugin list` or `codex plugin list | grep convex-codex-plugin`, then tell the user what was installed.
