Perplexity Comet alternatives

Compare options in ASE's browser & computer use category before treating any as a replacement for Perplexity Comet. Category membership and matching entity type do not prove equivalent capabilities. The directory below puts the same entity type first, then curated records alphabetically and repository-listed records by recorded GitHub stars. Stars measure interest, not users or performance. Check task fit, license, deployment and total costs; sponsorship never affects the order.

Compare Perplexity Comet head-to-head

Frequently asked

What is the best alternative to Perplexity Comet?: It depends on the capabilities, deployment requirements and costs you need. Browser Use is the first repository-listed option in this shortlist (117k GitHub stars); ChatGPT Agent is one of the commercial options. Compare capabilities, license, activity, and costs; this is not a performance benchmark.
Is there a free or open-source alternative to Perplexity Comet?: Browser Use, UI-TARS-desktop, and page-agent are among the repository-listed alternatives. Check each software license and deployment requirements before assuming it is open source or free to operate; model, API, hosting, and managed-service costs can apply.
How are these Perplexity Comet alternatives ranked?: Every other record in the browser & computer use category is a candidate; the page shows a bounded shortlist. Records sharing the subject’s entity type come first, then repository-listed records are ordered by recorded GitHub stars. Stars do not measure task performance or prove current maintenance. Commercial products are listed separately, with the same entity-type priority and alphabetical order within each group, because stars do not measure commercial adoption. Sponsored placement is always labeled and never affects the ranking.
