AutoFlow Engine v0.4.0|Durable Inngest DAG Execution & Envelope Vault

Visual workflow automation with executions you can actually inspect & debug

Build resilient backend graphs on a visual canvas, run them durably with step-level retries and cryptographic credential isolation, and trace every payload in real time.

Engine Architecture

Engineered for reliability, not demoware

Most workflow builders fail silently in production when APIs time out or keys rotate. AutoFlow is built from the ground up with durable execution, zero-leak secrets, and deep observability.

Durable Orchestration

Crash-Proof Step Execution

Workflows compile to a topological DAG and run as durable Inngest steps. If a 3rd-party API drops or rate-limits, only that step retries with exponential backoff — your upstream nodes never re-execute.

Guardrails

Topological sorting with strict DAG cycle detection
Step-level memoization & automatic backoff retries
Deterministic replay without re-billing AI tokens

Envelope-Encrypted Secrets

API keys, OAuth tokens, and database connection strings are encrypted at rest with AES-256-GCM using per-record data encryption keys (DEK). Decryption happens at a single runtime injection point.

Zero plaintext read path in database or API
Credentials automatically stripped from execution traces & logs
Tenant-scoped key isolation and credential revocation

Zero Silent Failures

Every node run captures exact timestamps, latencies, input payloads, output responses, and error traces. Real-time channels stream node statuses directly to the canvas as they execute.

Per-node IO inspection with deep JSON diffing
Realtime SSE status indicators on live canvas nodes
Immediate alert dispatch on unrecoverable step failure

Isomorphic, Type-Safe Node SDK

Every node is defined with strict Zod schemas. Node definitions are isomorphic (client-safe for forms & palettes), while executors are strictly server-only with zero runtime leaks.

Single Zod schema powers UI forms, canvas validation & engine
Isomorphic manifest keeps client bundle ultra-lean
Handlebars expressions evaluated with AST safety

Extensible Node Ecosystem

Connect your stack with zero friction

Pre-built triggers, AI models, databases, and communication nodes — all validated with strict Zod contracts and encrypted credentials.

TypeScript First

Clean developer ergonomics, zero magic

AutoFlow enforces an isomorphic boundary: client-safe Zod definitions drive the UI canvas, while strictly isolated server executors run inside durable Inngest step workers.

// src/nodes/ai/anthropic/definition.ts
import { z } from "zod";
import type { NodeDefinition } from "@/nodes/types";

export const configSchema = z.object({
  model: z.enum(["claude-3-5-sonnet-20241022", "claude-3-haiku-20240307"]),
  prompt: z.string().min(1, "Prompt template is required"),
  temperature: z.number().min(0).max(1).default(0.7),
  credentialId: z.string().min(1, "Anthropic API Key required"),
});

export const definition: NodeDefinition<z.infer<typeof configSchema>> = {
  type: "ai.anthropic",
  version: 1,
  category: "AI",
  label: "Anthropic Claude",
  description: "Execute reasoning tasks with Claude 3.5 Sonnet",
  icon: "Sparkles",
  configSchema,
  defaults: {
    model: "claude-3-5-sonnet-20241022",
    prompt: "Summarize the customer ticket: {{trigger.output.body}}",
    temperature: 0.7,
    credentialId: "",
  },
  inputs: [{ id: "input", label: "Context" }],
  outputs: [{ id: "output", label: "Analysis" }],
  credentials: [{ key: "credentialId", type: "anthropic.api-key", required: true }],
};
