Data-backed guides and comparisons for choosing open-source AI agents, coding agents, frameworks, guardrails, memory systems, and agent infrastructure.
24 of the 30 most-starred AI agents ship with no build provenance. Here's the full list, the six that get it right, and why stars are the wrong way to choose an agent.
Read article →122 million weekly downloads, zero proof the package matches the source code. 83% of AI agents ship without build provenance. Here's what sits in the gap.
Read article →GitHub stars measure popularity, not trustworthiness. Here are the evidence-based signals that actually help evaluate whether an open-source AI agent is safe to adopt.
Read article →375k stars, 184k stars, 167k stars — and zero build provenance. We checked the 10 most-starred AI agents. Eight ship without any package attestation.
Read article →Claude Code has more stars. Codex ranks dramatically higher on HVTracker. The gap comes from provenance, signed commits, and public verifiability.
Read article →opencode (167k stars) ranks #127. GPT Pilot has 1% signed commits. Only one coding agent cracks the global top 10.
Read article →LangGraph #1, AutoGPT #39, LlamaIndex #126, smolagents #138. Stars don't tell this story — provenance, scorecards, and signed commits do.
