WA-AKG turns ordinary WhatsApp numbers into a programmable messaging API, so your apps, CRMs, and automations can send and receive WhatsApp messages through a dashboard and REST endpoints instead of a phone. Connect several numbers at once by scanning QR codes, and each session stays visible with its connection state, ready for messages, media, documents, and stickers. The scheduler queues text and media for exact delivery times, and broadcasts go out in batches with randomized delays that keep sending patterns human. Keyword auto-replies answer common questions around the clock in private chats, groups, or both, with whitelists and blacklists deciding who the bot engages. Webhooks forward incoming messages, connection changes, and group events to your own systems in real time, and an n8n node plugs the gateway straight into workflow automations. Contacts sync with verified names and profile pictures, a sticker maker with background removal handles media chores, and the full API is documented in Swagger for client generation. The dashboard speaks English, Bahasa Indonesia, and Brazilian Portuguese, so support teams can run campaigns and customer conversations from the browser.

TextBee turns an Android phone with a SIM card into an SMS gateway your applications can call, so one-time codes, alerts, reminders, and two-way conversations go out as ordinary texts from a real number. Pair a phone by scanning a QR code in the dashboard, then send messages from the REST API, the dashboard, or the JavaScript SDK. Bulk campaigns load from a CSV file and are paced to stay within carrier limits, and any message can be scheduled up to 72 hours ahead. With several phones or SIM cards attached, each message can name the device and SIM it should use. Every message moves through pending, dispatched, sent, delivered, or failed, and the history view lists all devices together. Incoming texts appear in the dashboard and the API, and webhooks push received messages and delivery reports to your server with an HMAC-SHA256 signature you can verify. An official MCP server lets AI assistants send texts and read replies. API keys, devices, usage, and webhook subscriptions are all managed from one web interface.

Evolution API gives your applications a production-ready REST interface to WhatsApp, supporting both free Baileys-based Web connections and Meta's official Business Cloud API from the same server. With 9,200+ stars and 7,100+ forks, it is the most widely deployed WhatsApp integration layer available. Each installation handles unlimited isolated instances (one per phone number) with independent auth, webhooks, and database separation via Prisma ORM against PostgreSQL or MySQL, cached through Redis. Message types include text, images, audio, video, documents, contacts, locations, interactive buttons, list messages, carousel cards, and PIX payment links through unified endpoints. Native integrations connect to Typebot for chatbot flows, Chatwoot for multi-agent support, Dify and OpenAI for AI conversations, N8N and Flowise for workflow automation, and RabbitMQ, Kafka, or SQS for enterprise event streaming. Socket.io delivers real-time message and connection events. Amazon S3 or MinIO handles media offloading. The Evolution Manager v2 dashboard provides visual instance creation, QR code scanning, connection monitoring, and integration configuration without touching the API directly. Docker Compose bundles the server, PostgreSQL, and Redis with environment-variable-driven setup.
