Build guide

1. 01Database Schema & Auth Setup

   Initialize the Next.js project with better-auth and set up PostgreSQL tables for users, workflows, steps, and encrypted credentials.

   Scaffold a new Next.js application using TypeScript and Tailwind CSS. Configure better-auth with email/password authentication connected to a Supabase PostgreSQL instance. Create migration SQL files for the following tables: 'workflows' (id, user_id, name, is_active, trigger_config), 'workflow_steps' (id, workflow_id, step_order, app_name, action_type, field_mapping), 'workflow_runs' (id, workflow_id, status, execution_logs, started_at, completed_at), and 'credentials' (id, user_id, provider, encrypted_token_data). Ensure all token payloads use AES-256 encryption fields before storing. Implement the database connection layer using Prisma or Drizzle ORM.

2. 02Workflow Visual Canvas & Editor UI

   Build an interactive drag-and-drop workflow editor using React Flow where users can string together triggers and multiple action steps.

   Build a visual workflow editor page using React Flow within the Next.js dashboard. The interface should allow users to add a Trigger node (e.g., Webhook or Schedule), connect multiple Action nodes (e.g., Slack, Gmail, Custom API), and insert conditional If/Else branching nodes. Include a configuration slide-over panel for each node where users can map data fields from previous steps using handlebars syntax (e.g., {{step1.payload.email}}). Validate that nodes snap together properly and save the graph state cleanly as a JSON workflow definition to the 'workflows' table.

3. 03Asynchronous Workflow Execution Engine

   Implement a durable workflow runner using Inngest to parse step definitions, execute sequential or branched actions, and manage auto-retries.

   Integrate Inngest into the Next.js backend to serve as the durable workflow execution engine. Create an Inngest function 'execute-workflow' that triggers when an incoming webhook or cron event fires. The function must load the workflow steps from the database, evaluate any If/Else filter conditions (supporting operators like 'equals', 'contains', 'greater_than'), process inline data modifiers (such as text lowercasing, length limiting, and string replacement), and execute external API requests with automatic exponential backoff retries for up to 10.5 hours on failure. Record each step execution status and payload inside the 'workflow_runs' table for history logs.

4. 04AI Automation Builder

   Integrate the Vercel AI SDK to let users generate multi-step workflow configurations from plain-language text prompts.

   Implement an AI Automation Builder feature using the Vercel AI SDK and Anthropic API. Create an API route that accepts a natural language description of an automation (e.g., 'When a new row is added to Google Sheets, check if the status is Urgent, and send a Slack message'). The AI model should return a structured JSON object matching our workflow step schema (Trigger -> Condition -> Action). Wire up a chat or prompt input box on the frontend that parses this JSON response and automatically populates the React Flow canvas with the generated nodes and field mappings.

5. 05Data Modifiers & Condition Routing

   Build runtime execution blocks for data transformation modifiers and multi-path branch routing.

   Write utility functions and execution handlers for Integrately-style data modifiers and conditional routers. The modifiers must handle text transformations before data hits destination apps: calculate text length, limit length, remove extra whitespaces, replace text strings, change case (lower, upper, title, camel), and extract substrings using index positions or delimiter markers (e.g., 'extract text after @'). Ensure these modifiers execute inline as intermediary steps within the Inngest workflow runner without crashing the parent execution context.

6. 06Execution History & Error Debugging Dashboard

   Create a monitoring dashboard to inspect workflow runs, review execution logs, and trigger manual retries for failed tasks.

   Develop a 'History & Logs' dashboard page in Next.js that displays all past workflow execution runs with timestamps, status badges (Success, Failed, Retrying), and task consumption counts. Clicking a run should open a detailed step-by-step drawer showing exact input payloads, output responses, and error messages. Include a 'Retry Failed Tasks' button that triggers an Inngest background function to replay failed steps from the point of failure after user configuration updates.
