TypeScript and Node.js make up the biggest part of the x402 ecosystem — middleware for Express, Hono and Next.js, client SDKs, and agent frameworks. If you ship a JavaScript backend, there is almost certainly a drop-in x402 paywall for it, often installable in under ten lines of code.
These are the TypeScript / JavaScript projects in the directory, sorted by stars.
The TypeScript category right now
Of the 861 TypeScript projects in the index, 19 have real traction (100+ stars) and 372 have none yet. ClawRouter is the reference point at 6,661★. The median is 1★ — useful context before you pick a dependency from this list.
If you are choosing a stack, note that TypeScript (76%) and JavaScript (16%) carry most of the TypeScript work, much of it from nirholas, azeth-protocol, up2itnow0822. Projects tag themselves with x402, ai-agents, mcp more than anything else.
Freshness matters more than star count in a category this young: 213 projects shipped code in the last month, 381 in the last quarter, and 53 have not been touched in over a year. In short, activity is uneven — check the last-commit date before adopting. Newest addition: AgentFund (2026-07).
