AI Agent Infrastructure: AgentMail, AgentLine, AgentCard, Daytona, and More

A recent r/clawdbot post catalogs companies that are rebuilding the primitives humans take for granted as APIs for AI agents. The pattern is consistent: every capability a human employee expects — email, phone, payment, computer, browser, memory, SaaS tooling — is being rebuilt for agents.
Agent-specific tools
- AgentMail — gives agents email accounts
- AgentLine — gives agents a phone number
- AgentCard — lets agents pay for things
- Daytona / E2B — gives agents their own computers (cloud sandboxes)
- Browserbase / Browser Use / Hyperbrowser — lets agents use web browsers
- Firecrawl — lets agents crawl the web without a browser
- Mem0 — lets agents remember things (persistent memory)
- Composio — lets agents use your SaaS tools (integrations)
The original poster invites the community to add more tools in the comments. The list is a practical starting point for developers building agentic systems that need to interact with real-world services.
