Frequently asked

What is the best alternative to BettaFish?
It depends on whether you'd rather self-host or buy a managed product. TrendRadar is the most widely-adopted open-source alternative (62k GitHub stars); Consensus is one of the commercial options. Compare the full list above on adoption, license, and pricing.
Is there a free or open-source alternative to BettaFish?
Yes. TrendRadar, khoj, and storm are open-source research & data agents you can self-host for free — you still pay for the infrastructure you run them on and any model or API usage. See the ranked open-source list above.
How are these BettaFish alternatives ranked?
Every product in the research & data agents category is a candidate. Open-source alternatives are ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used, not abandoned. Commercial products are listed separately and alphabetically, because stars don't measure commercial adoption. Sponsored placement is always labeled and never affects the ranking.
