Open-source Ada alternatives

Chatwoot is an open-source, self-hostable customer support platform that gathers all customer conversations into one inbox. It is presented as an alternative to Intercom, Zendesk and Salesforce Service Cloud, and aims to give businesses control over their customer data while managing conversations across channels.

The shared inbox takes in website live chat, email, SMS and messaging channels such as Facebook, Instagram, Twitter, WhatsApp, Telegram and Line. An AI agent called Captain automates replies to common questions to reduce agent workload, and a built-in Help Center portal lets you publish articles and FAQs so customers can find answers themselves. Collaboration tools include private notes with mentions, labels, canned responses, auto-assignment based on availability, custom views and filters, a command bar and multi-language support.

Chatwoot is built with Ruby on Rails and Vue and can be run with Docker, with deployment guides on its help center. The repository license is listed as 'Other', so confirm which parts are open source. A hosted cloud version is also available for teams that prefer not to maintain their own server.

Botpress is a platform for building chatbots and AI assistants powered by large language models such as OpenAI's GPT. Its Botpress Cloud product is the main way to build and run agents, and this repository holds the open-source parts that surround it. It is written in TypeScript and released under the MIT license.

The repository contains the public integrations on the Botpress Hub that Botpress maintains, the developer tools for Botpress Cloud including the CLI, SDK and API client, examples of bots written as code with the SDK and CLI, and plugins for Botpress Studio. Developers can create their own integration from a template using the CLI and publish it to the Hub without forking the repository.

Contributions are welcome through pull requests and issues for the code in the repository, while Discord is suggested for faster responses about Cloud issues. On-premise Botpress version 12 is maintained in a separate repository, which is where problems with that version belong.

Dograh is an open-source platform for building voice AI agents that can make and receive phone calls. It describes itself as a self-hostable alternative to Vapi and Retell, and promises full code transparency with no vendor lock-in. Agents are designed in a visual workflow builder and can be tested quickly before going live.

The platform supports bring-your-own-key setups across speech-to-speech models or a pipeline of language model, speech-to-text and text-to-speech providers, including local models. It is MCP-native, so AI coding assistants can help design and edit agents, and it includes telephony support for inbound and outbound calling, with Asterisk ARI among its topics. It is written in Python and builds on the Pipecat framework.

Dograh is released under the BSD 2-Clause license and can run on premises or in a hosted cloud, with the vendor operating an app site. It suits support, sales and operations teams that want to automate calls while controlling data and provider choice.
