Visual Designer

Visual Workflow Designer

A full-featured diagram editor with 20+ purpose-built node types. Design complex automation visually — from simple sequences to parallel branches with error handling.

01

Drag-and-Drop Canvas

Build workflows visually on an infinite canvas. Drag nodes, draw connections, and see your logic take shape in real time.

Business logic becomes visible and understandable to everyone, not just developers.

02

Smart Connections

Sequence flows, success/error paths, timeout flows, and conditional branches. Every connection type with automatic routing.

Error handling and branching logic are visual, not buried in code — reducing bugs and misconfiguration.

03

Properties Panel

Configure every node inline. Set prompts, map variables, define conditions, wire integrations — without leaving the designer.

Configure everything in context — no switching between screens or digging through documentation.

04

Version Control

Every save creates a versioned draft. Publish when ready. Roll back anytime. Draft and production versions run independently.

Test changes safely in drafts. Roll back instantly if production breaks. Zero-downtime deployments.

20+ Node Types

Every node is purpose-built for a specific workflow pattern. Tasks execute logic, events control flow timing, gateways branch and merge, and special nodes handle waiting, looping, and agent orchestration.

AI Engine

AI Engine

Every workflow step can think. Embed LLM intelligence at any point with tool calling, RAG retrieval, conversation memory, and dynamic UI generation.

01

LangChain4j Integration

Native LangChain4j under the hood. Tool calling, structured output, streaming, and function definitions — wired directly into the workflow engine.

This means your AI agents can do real work — not just generate text, but take actions across your systems.

02

Tool Calling

AI agents invoke tools mid-execution — call APIs, query databases, run scripts, and feed results back into the conversation automatically.

Your AI doesn't just suggest actions — it executes them, reducing the gap between decision and outcome.

03

RAG Knowledge Base

Attach vector store collections to any AI agent. Documents are chunked, embedded, and retrieved at query time for grounded responses.

AI responses are grounded in your actual documentation, reducing hallucination and building trust.

04

Conversation Memory

Persist conversation history across workflow steps. AI agents remember prior context within a flow execution, enabling multi-turn reasoning.

Complex processes that span multiple steps no longer lose context — the AI remembers everything.

05

A2UI Protocol

AI agents generate interactive UI — forms, tables, cards — directly in chat during execution. The AI decides what to render based on context.

No frontend engineer needed — the AI builds its own interface when it needs human input.

06

Multi-Model Support

Switch providers per node. OpenAI, Anthropic, Google Gemini, and Ollama for local models. No vendor lock-in.

Use the best model for each task. Run sensitive data through local models while using cloud for everything else.

Execution Engine

Execution Engine

An actor-based runtime that executes workflows with isolated concurrency, pluggable messaging, and five ways to trigger any flow.

01

Actor Model

Each node runs as an isolated actor with its own mailbox and thread pool. Failures are contained — one node crashing never takes down the engine.

This means one failing integration never takes down your entire workflow — failures are isolated by design.

02

Parallel Execution

Parallel gateways fork into concurrent branches. The engine executes them simultaneously, merging results when all branches complete.

Complex processes that used to take hours of sequential processing now complete in minutes.

03

Pluggable Message Queues

Swap messaging backends without code changes. Kafka for production scale, Hazelcast for clustering, database-backed for simplicity.

Start simple, scale to millions of events — without rewriting your workflows.

04

Real-Time Monitoring

Track every execution as it happens. See which node is active, inspect variable values, view execution timelines, and diagnose failures.

When something goes wrong, you know exactly where and why — no more black-box debugging.

5 Trigger Types

Workflows start from any source. Schedule them, listen for events, expose HTTP endpoints, or kick them off manually.

Scheduled

Cron-based triggers. Run workflows on any schedule.

Email

Trigger on inbound emails via Nylas webhooks.

Webhook

HTTP endpoints that start workflows from any system.

Event

Internal domain events. React to system changes.

On-Demand

Start manually via API or UI.

Security

Enterprise-Grade Security

Built for regulated industries. Multi-tenant isolation, encrypted secrets, role-based access, and the option to deploy entirely on your own servers.

01

Multi-Tenant OIDC/JWT

Full OpenID Connect authentication with dynamic JWKS validation. Each tenant gets its own issuer, isolated by design.

Each customer's data and workflows are completely isolated — a requirement for regulated industries.

02

API Keys

Machine-to-machine access via bcrypt-hashed, rate-limited, org-scoped API keys. Revoke instantly. Full audit trail.

Integrate apptor into your existing CI/CD and automation pipelines with secure, auditable access.

03

Role-Based Access Control

Three tiers: Super Admin, Org Admin, and Flow Creator. Permissions cascade by organization with fine-grained scoping.

The right people see the right things — no accidental exposure of sensitive workflows.

04

AES-256 Encryption

Secrets, credentials, and sensitive data encrypted at rest with AES-256. Keys managed via AWS Secrets Manager or environment variables.

Your secrets and credentials are protected at rest — meeting enterprise security baselines.

05

Audit Trail

Every action is logged. Workflow executions, user actions, API calls, and configuration changes — all timestamped and immutable.

Full accountability for compliance — every action traced, timestamped, and immutable.

06

On-Premise Deployment

Deploy on your own infrastructure with Docker. Multi-tenant SaaS, single-tenant dedicated, or fully on-prem.

Your data never leaves your network. Full compliance with GDPR, DPDP, and industry regulations.
