Stacker
AI agents that get work done.
About Stacker
Stacker is an AI agent platform that connects to your business tools and data, then carries out tasks such as drafting emails, updating CRM records, building reports, and running scheduled workflows. It grew out of Stacker's no-code app builder, and every plan still includes white-label customer portals with custom domains. Agents are reachable from Slack, email, SMS, Telegram, and voice, and pricing is credit-based with no per-seat charges.
Pros & Cons
Pros
- No per-seat pricing: the whole team shares one credit pool
- Generous $100 free trial credit with no credit card, and trial credits never expire
- Every plan includes all features, integrations, and channels rather than gating them by tier
- Agents work inside Slack, email, SMS, and voice, so teams do not need to adopt a new interface
- White-label customer portals with custom domains are still included for existing portal use cases
- SOC 2 compliant, backed by a16z and Y Combinator, with a long customer list from its no-code era (Segment, TED, Zapier, Meow Wolf)
Cons
- Credit-based billing makes monthly cost hard to predict; complex projects use 20-50 credits each
- Monthly credits reset each cycle and agents pause when credits run out
- The agent product is new after the pivot from no-code apps, so most public reviews describe the older Airtable-based portal builder
- Former no-code app builder users may find the product direction changed significantly
Key Features
Task-based AI agents
Describe a task in plain language and an agent connects to your tools, does the work, and returns the output, from content drafts to sales proposals and order summaries.
2,000+ integrations
Connects to Salesforce, HubSpot, Airtable, Stripe, Notion, Google Sheets, Gmail, Snowflake, Postgres, and more so agents read and write data where it already lives.
Computer use
Agents can click, navigate, and act in web apps directly, covering tools that have no API.
Multi-channel access
Talk to agents from Slack, email, SMS, Telegram, the web workspace, or by voice with spoken summaries back.
Scheduled runs and automations
Set recurring jobs such as daily standups, Monday recaps, or month-end reports that run without prompting.
Multi-agent coordination
Hand off steps of a longer workflow between specialist agents.
White-label customer portals
Build unlimited branded customer portals on custom domains, carried over from Stacker's no-code portal builder.
Knowledge base and memory

Custom skills and code execution
