Our verdict on Stacker
Stacker is a no-code, AI-powered platform for creating business applications, customer portals, partner portals, internal tools, and workflow apps. Teams can describe requirements in conversational threads while the platform generates tables, pages, permissions, portals, and agent configurations. Its strongest fit is organizations building customer-facing data experiences that need structured records, authenticated access, branded pages, forms, and controlled views without developing each component from scratch.
The published plans show a paid Standard tier at $50 USD per month, including 250 credits per month, unlimited agents, all 2,000+ integrations, unlimited customer portals, white-label portals, and custom domains. Enterprise adds custom credit volumes, dedicated onboarding, SLA and priority support, security review and DPA, SSO, advanced access controls, and custom integrations. There is also a free credit-based trial, but no perpetual $0 plan. Integrations cover business systems such as Salesforce, HubSpot, Pipedrive, Stripe, Xero, QuickBooks Online, Airtable, Asana, Calendly, Notion, Monday.com, ClickUp, Google Sheets, Gmail, and PostgreSQL.
Stacker’s standout depth is its combination of portal delivery and operational automation. AI worker agents can update records, send follow-ups, and run scheduled tasks, while recurring synchronization connects external data to built-in tables. Magic links or one-time codes handle portal authentication, and the REST API supports reading and writing app data. The trade-off is focus: teams seeking primarily internal tools may find the monthly entry price harder to justify, especially without a perpetual free plan. Choose Stacker when customer-facing portals, permissions, integrations, and automated workflows are central; consider another option when you need a lower-cost internal-tools starting point or broader application coverage beyond the web.
