Fynt

A clean alternative to n8n and Zapier that puts AI-native workflows front and center, Fynt is the MIT-licensed workflow automation platform where you drag nodes onto a React Flow canvas, wire them together with typed connections, and let a distributed BullMQ engine execute them — with every step streamed live to your browser over WebSockets so you never wonder what happened inside a run. The node library spans triggers (manual, webhook, cron scheduling), AI providers (OpenAI, Anthropic, and Gemini with structured output parsing), service integrations (GitHub webhooks, Notion databases, Slack channels, Discord bots, arbitrary HTTP endpoints), logic gates (conditional branching, filtering, data transformation), and utility nodes (delay, logging, payload mapping). The execution architecture separates concerns across three services: a Next.js 16 web application serving the React 19 workflow builder and tRPC API, a BullMQ worker processing jobs with node-level retries and checkpointing for crash-safe execution, and a dedicated WebSocket relay server broadcasting real-time run events via Redis Pub/Sub. All stored credentials are encrypted at rest using AES-256-GCM with per-credential initialization vectors. The full-stack deploys as a single Docker Compose stack (web, worker, realtime, PostgreSQL, Redis) or individually via pnpm workspaces in a Turborepo monorepo. Authentication is handled through better-auth with configurable OAuth providers. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Benefits

  • Visual Node Editor with Live Streaming
  • Build workflows by dragging nodes onto a React Flow canvas and watch every execution step stream live to your browser over WebSockets with real-time status indicators and output previews.
  • AI-Native Workflow Pipelines
  • Chain OpenAI, Anthropic, and Gemini calls as first-class workflow nodes with structured output parsing, enabling multi-model reasoning, summarization, and decision-making within automation flows.
  • Crash-Safe Distributed Execution
  • BullMQ on Redis provides node-level retries, job checkpointing, and crash-safe execution guarantees, ensuring long-running multi-step workflows resume correctly after any interruption or failure.
  • Full Self-Host with Encrypted Credentials
  • Deploy the complete stack via Docker Compose with PostgreSQL and Redis included, while all stored API keys and OAuth tokens are encrypted at rest using AES-256-GCM with per-credential initialization vectors.

Features

  • Visual Workflow Builder
  • Drag-and-drop node editor built on React Flow with typed connections, live validation, and a growing library of trigger, AI, integration, and logic nodes.
  • Multi-Provider AI Nodes
  • First-class OpenAI, Anthropic, and Gemini integration nodes supporting chat completions, structured output parsing, and chained multi-model reasoning within workflows.
  • Real-Time Execution Events
  • Dedicated WebSocket relay server broadcasts execution progress via Redis Pub/Sub, showing node-by-node status, output payloads, and error details as they happen.
  • Service Integrations
  • Pre-built nodes for GitHub webhooks, Notion databases, Slack messaging, Discord bots, HTTP endpoints, and cron scheduling with OAuth credential management.
  • Docker Compose Deployment
  • Single docker-compose.yml deploys web, worker, realtime, PostgreSQL, and Redis services in full self-host mode with environment-based configuration.
