M Mermaduckle AI Workflow Platform
Hosted beta · Public demo · Private deployment

The control plane for AI workflows in production.

Mermaduckle gives teams a visual workflow builder, approval gates, agent management, secrets handling, and audit trails in one Rust-based control plane. Try the public demo with sample data, request access to the hosted beta, or run the platform in your own environment.

/demo is safe for public evaluation. /app is the real hosted beta for invited testers and design partners.

What you can do

From prototype to production in one platform.

🔧
Engineering

Build multi-step AI pipelines with approval gates before they touch production systems

🛡️
Security & Compliance

Audit every AI action, review sensitive operations, export compliance reports

🤖
AI/ML Teams

Manage agent configurations, test prompts, orchestrate multi-agent workflows

⚙️
DevOps

Run the app on Fly or Railway, connect to managed Postgres, and operate with webhooks and schedules

Platform

Everything you need to run AI workflows in production.

Not a prototype or a builder-only tool. Mermaduckle ships the workflow studio, approval queue, audit trail, agent library, secrets management, and deployment tooling in one integrated surface.

Visual Workflow Studio

Drag-and-drop builder with import/export, AI-assisted generation, run history, and real-time debugging.

  • Create, edit, and connect nodes visually
  • AI Architect generates workflows from prompts
  • Import/export workflows as JSON

Human-in-the-Loop Approvals

Pause high-stakes workflow steps for human review before they execute. No more "hope it works" deployments.

  • Approval queue with context and metadata
  • Approve or reject with audit trail
  • Block sensitive actions automatically

Audit & Governance

Every action logged. Every run inspectable. Export compliance reports as CSV with one click.

  • Full event history with actor, target, and metadata
  • Severity-based filtering and search
  • One-click CSV export for compliance

Agent Library

Configure, test, and manage AI agents with full control over models, prompts, tools, and runtime behavior.

  • Per-agent model and prompt configuration
  • Tool binding and custom parameters
  • Performance metrics and cost tracking

Secrets & API Keys

Encrypted secrets vault, scoped API keys with rotation, team RBAC, and integration management.

  • Argon2-hashed API keys with scopes
  • Encrypted environment secrets
  • Role-based access (admin/user)

Webhooks & Schedules

Trigger workflows from external events or run them on a cadence. Full webhook logs and health monitoring.

  • Cron-based scheduling per workflow
  • Webhook endpoints with payload logging
  • Health checks and system status dashboard
How we compare

Purpose-built for governed AI workflow execution.

Other tools optimize for connector breadth or visual composition. Mermaduckle is built for the moment your AI workflows need approval gates, audit trails, and production-grade operational control.

Access model

See the product publicly. Use the real app selectively.

Mermaduckle separates public evaluation from real product access. /demo runs sample workflows and dummy data for anyone to inspect. /app is the live hosted beta for invited testers. Teams that need stricter control can still deploy the same product in their own environment.

Deployment

Hosted beta now. Private deployment when control matters.

We use the hosted beta to learn with early users while keeping a clean path to private, customer-owned deployments. The app tier runs in Rust, the data layer runs on Postgres, and the service can move between Fly, Railway, or your own stack.

Public demo

Explore the product without risking real data.

The demo route is filled with sample workflows, approvals, audit activity, and settings so buyers can see the product without entering production secrets.

Hosted beta

Run the real app with invited users.

The hosted beta at /app is where we test the live control plane with design partners while the product matures.

Private deployment

Keep production under customer ownership.

When teams need stronger data ownership, run the same Rust service on Fly, Railway, or another container platform against Postgres.
