Relay.app

Relay.app is an AI automation platform that helps businesses build reliable workflows and agents connecting more than 200 SaaS apps with leading language models. Users describe automations in natural language through a chat-first builder powered by Claude Opus 4.8, then refine flows in a visual editor with paths, loops, waits, and human-in-the-loop approvals. Relay.app targets operations teams, founders, consultants, and engineers who want Zapier-class connectivity with stronger AI steps and review checkpoints.

Key Features

• Chat-first AI builder: Describe automations in plain language and Relay.app assembles editable workflows with connected app steps.
• 200+ app integrations: Trigger and act across CRMs, email, spreadsheets, payment, support, and developer tools.
• Human-in-the-loop steps: Pause runs for approvals, manual data entry, or AI output review via email or Slack.
• AI steps with bundled credits: Use GPT, Claude, Gemini, and other models with monthly AI credits or your own API keys.
• Sequences and tables: Reusable sub-workflows and structured data tables support enrichment, routing, and reference data.
• MCP server support: Expose custom tools to external AI clients like ChatGPT or Claude through Model Context Protocol servers.
• Advanced flow control: Branching paths, merged paths, dynamic waits, webhooks, scraping, PDF utilities, and custom JavaScript.

Supported Triggers and Actions

Relay.app workflows start from app events, schedules, manual buttons, public forms, webhooks, mailhooks, RSS feeds, or table updates. Action steps read and write records across connected SaaS tools with nested object access, reducing extra lookup steps. HTTP and webhook utilities cover APIs without native connectors. Web scraping steps extract page content, screenshots, and crawl results for enrichment pipelines.

Pricing and Plans

Plan	Annual Price	Usage
Free	$0	1 user, 200 steps/month, 500 AI credits/month, 5 workflows, 2 MCP servers
Professional	$19/month billed annually	1 user, 750 steps/month, 2,000 AI credits, unlimited workflows
Team	$59/month billed annually	10 users, 1,500 steps/month, shared workflows and connections
Enterprise	Custom	Custom limits, SOC 2 and GDPR compliance, priority support, private models

Triggers, many transformations, and path evaluations do not count as billable steps. Teams can upgrade step and AI credit bundles on annual plans.

Pros and Cons

Pros:

• Human-in-the-loop design suits finance, HR, and customer workflows needing approvals.
• All features available on free tier for realistic prototyping before upgrade.
• Strong G2 ratings praise testing UX and responsive support.
• SOC 2 compliance and optional private model hosting on enterprise tiers.

Cons:

• Free plan limits active workflows to two and retains only 30 days of run history.
• Team collaboration requires upgrading from single-user Professional pricing.
• Heavy automation volume can exhaust step quotas without paid top-ups.
• Complex legacy enterprise integrations may still need custom code outside connectors.

Security and Reliability

Relay.app encrypts credentials at rest and supports SOC 2 compliance on enterprise plans for regulated industries. Run history shows step-level success and failure states, making it easier to debug broken automations without re-running entire workflows. Teams can duplicate proven flows into templates for client onboarding or internal IT requests. Optional private model hosting on enterprise tiers keeps sensitive prompts inside approved infrastructure boundaries when legal review requires it. Webhook and mailhook triggers let external systems start workflows without building custom middleware first, which speeds up pilot projects and reduces engineering overhead.

Who Should Use Relay.app

Relay.app fits small businesses automating onboarding, invoicing, lead routing, and support handoffs, plus ops consultants replacing brittle Zapier chains. Teams wanting AI extraction, summarization, and classification with human review checkpoints benefit more than pure scheduler tools. Large enterprises with deep iPaaS investments may keep incumbent platforms but use Relay.app for AI-native agent prototypes.
