What Stacker is

Stacker provides web-based AI agents that connect to workplace tools, perform tasks, and return results for marketing, sales, finance, and operations teams. Agents can use computer controls to click through websites, including tools without an API. The Standard plan includes Slack, email, and web channels, scheduled tasks, automations, and more than 2,000 integrations. Workspace integrations must be connected before being enabled for individual agents. 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 monthly, unlimited agents, unlimited customer portals, and no per-seat charges. Credits reset each cycle, and agents pause when they run out. The Enterprise plan offers custom credit volumes, dedicated onboarding, SLA, and priority support. Stacker also offers $100 in free credits without a credit card, and those credits never expire.
