Relay.app
Relay.app is built for cross-app automation that stays readable and maintainable long after it ships, which makes it a strong alternative to Happycapy’s more “agent in a sandbox” approach. Instead of centering on a computer-like environment, Relay emphasizes clear workflow ownership, so teams can understand what’s happening, update steps safely, and avoid brittle automations that nobody wants to touch months later.
It also shines when “safe automation” matters. Human-in-the-loop approvals are a core part of the product, making it practical for high-stakes operations like customer comms, admin actions, or anything that needs a sign-off before execution.
For teams, Relay leans into collaboration: shared workflows, run history, and debuggability help multiple people build and maintain the same system. If the goal is to orchestrate Gmail/Notion/Slack/CRMs with strong guardrails, Relay tends to feel more like an automation platform than an experimental agent workspace.
