What Stacker is

Stacker provides AI agents that connect to workplace tools, perform tasks, and deliver results across marketing, sales, finance, and operations. Agents can use computer controls to click through and navigate websites, including tools without an API. The Standard plan includes Slack, email, and web channels, scheduled tasks, automations, and all 2,000+ integrations. Workspace integrations need to be connected first, then enabled for each agent in its Tools settings. Stacker lists 32 built-in data connectors, including Salesforce, HubSpot, Stripe, Airtable, and Google Sheets. Its REST API reads and writes app data, with API keys scoped to a selected app. Standard costs $50 a month and includes 250 credits per month; its listed price is labeled “Early bird.” Credits reset each cycle, and agents pause when they run out. The plan includes unlimited agents and customer portals, with no per-seat charges. Stacker offers $100 in free credits without a card, and says they never expire. It describes itself as SOC 2 compliant. The service is available on web and via API.
