Cloud Free includes 2 users, 1 project, and 7-day retention. Paid Serverless includes unlimited users and projects with 30-day retention. Self-hosting requires your own infrastructure; Dedicated costs depend on the instance, region, and running time. | Source-available, not OSI open source. Optional browser tracking adds in-page signals. AI-answer monitoring uses your provider keys and paid API samples; it does not reproduce what every app user sees. No verified hosted data-region claim. |
