Open Source SMS Gateways

Android SMS Gateway is a self-hosted messaging infrastructure that transforms Android devices into programmable gateways for sending and receiving SMS and MMS messages. By exposing a local RESTful API and an SMPP bridge, the project enables developers to integrate cellular messaging capabilities directly into their own applications without relying on third-party cloud providers. The platform distinguishes itself through advanced traffic management and orchestration features designed for high-volume messaging. It includes a multi-SIM routing engine that distributes outgoing traffic across mult

SMSBoom is an API-based message dispatcher and bulk SMS messaging tool. It functions as a utility for managing recipient lists and automating the delivery of text notifications to large groups. The tool operates by making HTTP requests to external third-party messaging service providers and API gateways to trigger cellular network transmissions. It manages mass SMS outreach by processing collections of phone numbers to dispatch high volumes of messages.

Illa-builder is a low-code internal tool builder and API integration platform used to create business applications and admin panels. It functions as a database GUI dashboard and visual workflow automator, allowing users to connect to databases and external APIs to manage data and automate business processes. The platform provides a self-hosted app framework that can be deployed on private infrastructure via Docker. It enables the creation of custom dashboards and CRMs while maintaining full control over data and hosting. The system includes a visual drag-and-drop canvas for designing user in

Typebot is a visual chatbot builder and conversational platform designed for lead generation and data collection. It provides a drag-and-drop workflow designer that converts visual nodes into structured conversation logic, allowing users to build interactive forms and chatbots with conditional routing. The platform is designed as a self-hosted conversational infrastructure, enabling the deployment of the entire application stack on private servers using Docker and PostgreSQL. This allows for complete control over data storage and server maintenance. The system integrates with external servic

This is an open-source platform for creating, hosting, and interacting with persistent AI characters that maintain personality and memory across conversations. The system orchestrates the full lifecycle of an AI companion by combining character definitions, conversation history, memory retrieval, model abstraction, and external communication channels into a unified runtime pipeline. The platform enables users to define detailed character personalities through structured configuration files that shape conversational behavior, and supports multi-turn dialogue through a memory system that stores

Plain-app is a multi-purpose toolset for self-hosted device management, providing a web-based dashboard to remotely access files, system settings, and notifications on a mobile device over a local network. It functions as a remote gateway for SMS and notifications, a peer-to-peer file transfer system, and a media server for streaming content to browsers or casting to televisions via DLNA and Chromecast. The project emphasizes secure local connectivity, utilizing TLS and XChaCha20-Poly1305 encryption to protect traffic between the mobile device and the browser. It also includes a distraction-f

Botkit is a multi-platform chatbot framework designed to build conversational bots that operate across different messaging services using a unified interface. It provides a core system for multi-platform development, utilizing a platform adaptation layer to translate service-specific API payloads into a standardized internal format. The framework features a conversational dialog manager that coordinates multi-turn interactions through state-tracking, branching logic, and scripted flows. It employs a message processing middleware pipeline to intercept, normalize, and enrich incoming and outgoi

This project is an AI-driven phone agent platform and telephony gateway designed to automate inbound and outbound voice interactions. It functions as a conversational voicebot system that utilizes large language models to conduct natural language phone conversations for customer support and data collection. The platform distinguishes itself through the integration of retrieval-augmented generation, allowing voice agents to search internal knowledge bases for domain-specific answers during live calls. It features automated language detection to support multilingual conversations and a system f
