Build and test
faster with AI

Two built-in AI tools that eliminate the blank-canvas problem and make your workflows bulletproof before you ship.

✦ AI Workflow Generator

Describe it.
We build it.

Type a plain-English description of what you want to automate. Weavlin's AI generates a complete workflow — nodes, edges, names — and drops it straight onto your canvas.

✦
Generate Workflow with AI
Describe what you want to automate
Webhook → S3 → HTTP notify Postgres trigger → Lambda → respond
Receive a webhook, classify the document with Bedrock AI, save result to Postgres, then respond 200 OK|

⬡ AI Test Case Generator

Describe a scenario.
Get a payload.

Define a test scenario in plain English. Weavlin reads your workflow's node structure and generates a realistic JSON payload to trigger and validate your workflow end-to-end.

Role-based access
at every level

Org → Workspace → Project hierarchy with fine-grained permissions. Every action is logged.

🏢
Org Admin
admin
  • Org stats & member management
  • Workspace oversight
  • Workflow monitoring
  • Credential management
  • Audit log access
👤
Member
workspace_member
  • Dashboard & personal workspace
  • Workflows, executions, credentials
  • Workspace Admin: add/remove members
  • Assign workflow permissions
  • Feature-gated access (view/full)
// security & compliance

Built secure
by default

Enterprise identity, encrypted secrets, sandboxed code execution, and complete audit trails.

🔑
Identity & Auth
  • → AWS Cognito manages all passwords & MFA
  • → Cognito access + refresh tokens (no custom JWT)
  • → Token auto-injected via HTTP interceptor
  • → 15-minute expiring invite links with short codes
  • → Single-use invites — code invalidated on register
🗄
Data Isolation
  • → TypeORM subscriber auto-scopes queries by orgId
  • → Cross-org writes throw ForbiddenException
  • → AsyncLocalStorage seeds request context per-request
  • → Credentials AES-256-GCM encrypted at rest
  • → Secrets never returned by API (write-only)
🏖
Code Sandbox
  • → isolated-vm V8 sandbox — no Node.js API access
  • → 5-second execution timeout
  • → 64 MB memory limit enforced
  • → No fs, process, require — only fetch + console
  • → Console output captured to _logs field
📋
Audit & Access
  • → Full org-level audit log via /admin/audit-logs
  • → Route guards: authGuard, orgAdmin, superAdmin, feature
  • → /access-denied page with contextual messaging
  • → SQL injection prevention via quoteIdent()
  • → Postgres loop guard prevents self-triggering cascades
