Coverage earns its page here. Nothing gets a recommendation from a vendor landing page alone.

How research works

Every platform, framework, or tool we cover is researched against official SDK documentation, GitHub repositories, community forums, and third-party analyses. We source star counts from the referenced repositories at the time of publication. We source pricing from official pricing pages. We do not fabricate benchmark results or test claims we cannot reproduce.

When we quote numbers — star counts, download figures, funding amounts — we link the source. When a claim is from an internal evaluation we cannot reproduce, we say so explicitly. Posts get updated when platforms ship meaningful changes, with the update date shown at the top of the post. If a recommendation stops being right, we change the recommendation.

What we do not cover

Security-sensitive agent misuse guidance: prompt-injection attack cookbooks, credential-harvesting automations, or instructions for using agent capabilities to harm systems or people. Where safety-relevant topics arise (prompt injection defenses, safe autonomous agent patterns), we frame them defensively — how to protect your systems, not how to exploit others'.

How this site makes money

Two ways: display advertising, and affiliate commissions when you sign up for a tool through our links (at no extra cost to you). Monetization never decides a verdict — several platforms we cover have no affiliate program at all (LangGraph, CrewAI, Google ADK). The full policy is in our affiliate disclosure.
