Data-backed guides and comparisons for choosing open-source AI agents, coding agents, frameworks, guardrails, memory systems, and agent infrastructure.
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 →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.
