Rills: the Relay.app alternative
How Relay.app and Rills differ on AI oversight, pricing, and mobile approvals.
Relay added human-in-the-loop steps to a web builder. Rills was built around the approval itself: confidence scoring that learns your judgment, and a mobile queue you clear in seconds rather than a step buried in a flow.
- Relay bolts a human step onto a web flow; Rills is built around the approval
- Relay meters steps and AI credits; Rills keeps logic and approvals free
- Switch if you want a confidence learning loop and a mobile-first queue
Pick Rills if you want confidence-scored AI with a learning loop and a mobile-first approval queue as a core product surface.
Pick Relay.app if you want bundled AI credits inside a web-first builder with explicit human-in-the-loop steps.

Sources, verified June 2026: Rills pricing · Relay.app pricing
In Rills the approval is the product, not a step you add. The approval and the logic around it never cost credits, a paused workflow sits at $0, and confidence scoring learns per execution so the queue you clear from your phone keeps getting shorter.
Frequently asked questions
Is Rills a good Relay.app alternative?
Relay and Rills are the closest match in this list: both blend AI with human-in-the-loop steps. Rills differs by building the product around the approval itself, with confidence scoring that learns per execution and a mobile-first queue, rather than treating approval as one step inside a web flow.
What's the real difference between Rills and Relay?
In Relay, a human step is something you add to a flow. In Rills, the approval is the foundation: every consequential action proposes and waits, confidence scoring tracks which calls you trust, and runs that clear your confidence threshold go through on their own.
How much does Relay.app cost?
Relay.app's pricing, checked June 2026 at relay.app/pricing:
- Free: 200 steps and 500 AI credits per month, one user
- Professional: $38/month billed monthly (750 steps, 2,000 AI credits, one user)
- Team: $118/month (1,500 steps, 10 users included)
Annual billing roughly halves both paid tiers. Higher step caps raise the price, and AI credits meter every model call.
How does Rills pricing compare to Relay's credits?
Relay meters steps and AI credits, so logic, actions, and model calls all draw down. Rills separates workflow credits from AI credits and never charges for logic or approvals, and a paused workflow costs $0.
Run your own volume through the automation pricing calculator at rills.ai/tools/automation-pricing-calculator, or see rills.ai/pricing for current tiers.
Does Rills have a mobile approval queue?
Yes, the mobile approval queue is the core of Rills. You review and approve proposed actions from your phone in about five seconds. Relay supports human steps but is web-first rather than queue-first.
Does Rills bundle access to GPT and Claude like Relay?
Rills runs AI agents with included AI credits on paid plans. If your priority is bundled, out-of-the-box access to several major LLMs inside a single builder, Relay's AI credit model may suit that better; if your priority is supervised execution with a learning loop, Rills is the closer fit.
