How this page is made: a human editor decides what is published. Drafts are proposed by a mixture of models (Claude Opus 4.5, GPT Codex and DeepSeek’s strongest models) working from our own verified data — live site checks, current pricing and the public sentiment we gather from Reddit, Product Hunt, G2 and community forums — and the editor keeps, corrects or strikes each line. Nothing here is pay-for-placement. Read the full methodology.
