Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
Parse WebVTT, SRT, or TTML for conformance, timing, overlaps, line length, and reading speed.
Check that your AI is being logical. Free tool that mathematically catches contradictions in agent reasoning. No account needed. Also offers paid guardrails that converts natural language to formal verification proofs, that anyone can check succinctly.
Evidence-gated task verification for AI agents. Decompose goals into acceptance criteria, attach proof (screenshot, curl, file), independent LLM judge accepts or rejects. 24 tools. Hosted remote MCP (streamable-http, OAuth 2.1 + DCR).
Load testing and synthetic monitoring platform: test with Playwright, Browser Bot, or Protocol Bots.
Test curl retries locally or inspect remote 429/503 Retry-After traces; optionally share findings.
Runs your code against a contract; HELD or BROKE at the exact input. Deterministic. 0.10 USDC/call.
What is known to be broken in an MCP server or API operation, with the check that found it.
Explore Upforge services and evidence, or submit a prototype for a human-approved static fit check.
Pay-per-call MCP server. Vetted human experts review AI-generated content (text, images, video, audio, social posts), audit reasoning chains, run prepublish safety checks, and gate high-stakes actions for human approval. 7 paid tools at $1.00 each plus 4 free tools (list_offerings, list_expert_profiles, get_result, verify_certificate).

Verify artifacts, hand off public state, and record, check and find evidence about capabilities.
Compare two versions of a JSON row list: what was added, removed or changed, field by field.
Test FIX from Claude, ChatGPT, or Cursor: free sandbox FIX sessions or your own FIXSIM instances.
Check what a paid x402 endpoint or MCP server delivered, from probes anyone can repeat.
Scan any website or MCP server for agent readiness: 0-100 score, a fix per failing check. Free.
Pixel-perfect webpage screenshots rendered in a real browser, full-page or viewport, via one POST.
Check if your MCP server is ready to publish on the MCP Registry, Smithery, or npm.
