About Stacker+

Stacker started as a way to turn spreadsheets and databases such as Airtable into portals where clients, members or partners can log in and see their own records. Its pricing page now describes a credit-based platform with unlimited customer portals and AI agents. It could suit a charity that wants a login area for clients or volunteers but has no developer.

Pricing: Standard starts at US$50 a month for 250 credits and scales to US$2,000 a month for 10,000 credits; Enterprise is custom. Credits are shared by the team with no per-seat charge, and new users get US$100 of credits (no card needed). Each task uses credits depending on its complexity, so costs depend on use.
