How to choose
Match the channel first: WhatsApp-heavy teams should start with Estera or Hallo Zetta; multi-channel agencies need WebChatAgent or Cosmo. Check handoff quality and language coverage before volume. Watch for agents that require heavy custom integration versus plug-and-play; pricing usually scales with message volume or seats, so test on real ticket load to avoid surprise costs. Avoid tools that lack clear escalation paths or that train only on public data.

By real traction from our index (upvotes / MRR / growth rate, whichever the product actually has) — not editorial picks, and we do not accept paid placement. Sources: ProductHunt, Hacker News, GitHub, HuggingFace, Reddit, TrustMRR.
What is the inclusion bar?
A page is published only when at least 5 real products qualify. Judgement fields (autonomy, prerequisites, cost, integrations) all require a source quote — where we cannot read it, we leave it blank rather than guess.
