OpenWA
Library
Bots, notifications and automations through WhatsApp Web.
Node.js library that turns WhatsApp Web into a programmable API for bots, notifications and automations, with self-hosting and a paid plan for advanced features.
Why it belongs here. It turns WhatsApp Web into a programmable API. The v5 alpha includes an MCP server for connecting AI agents.
Its limit. Unofficial project: the repository warns that use is at your own risk. V5 is in alpha; the documented stable version is 4.76.0.
Run an instance, link WhatsApp through a QR code and use its interface to send messages and receive events. The core is free; some restricted features require a license key.
Compatibility and setupRequirements and agent differences
Compatibility. The documented stable version is 4.76.0 and runs on Node.js. The reviewed v5 alpha instructions describe interchangeable drivers and an MCP server; check before applying them to the stable branch.
Real cost and licenseResource, agent and extra costs
Cost. The core is free under the Hippocratic + Do Not Harm license. Some restricted features require a license key; check the terms published at openwa.dev before planning a deployment.
Example and alternativeWhen it helps and what else to use
Example. Launch the server with npx @open-wa/wa-automate@4.76.0 --port 8080, scan the QR code with your phone and send messages, receive webhooks or connect a bot from another application.
Alternative. The official WhatsApp Business platform or SaaS products that offer WhatsApp as a channel. Check each option's current requirements and terms.
Sources and reviewWhat is documented and what was tested

Meetily
App
Transcribing and summarizing meetings locally without sending data to the cloud
Open source meeting assistant that records, transcribes with Whisper and summarizes with local AI. Everything stays on your computer, without cloud storage or bots joining the call.
Why it belongs here. Meetily keeps recordings and transcripts on the user's computer. Summaries can also be generated there with a local model such as Ollama; choosing an external provider sends the transcript to that service. The Community edition is published under MIT.
Its limit. Linux requires building from source, and several advanced features belong to Pro. The dossier also contains no independent accuracy test.
In plain English: it listens to a meeting on your computer and writes down what is said without forcing you to store the audio in the cloud. The summary stays on the computer only when you use a local model.
Compatibility and setupRequirements and agent differences
Compatibility. Packages are available for macOS and Windows. Linux requires building from source; it works with meeting apps by capturing microphone and system audio.
Requirements. Published minimum requirements are 8 GB of RAM, a four-core CPU, 10 GB of storage, Node.js 18+, Python 3.10+ and FFmpeg; a GPU is optional.
Real cost and licenseResource, agent and extra costs
Cost. The Community edition is free under MIT. A Pro edition exists, but no price is published here because the dossier lacks a complete, official and dated euro conversion.
Example and alternativeWhen it helps and what else to use
Example. Use it to transcribe a client interview and then generate a local summary with Ollama, with the appropriate consent.
Alternative. The entry identifies Otter.ai and Fireflies.ai as replacements; the dossier lacks sufficient independent comparison to name an overall winner.
Sources and reviewWhat is documented and what was tested

OpenDroid
App
Automating everyday Android tasks through voice or text commands with an autonomous AI agent
Autonomous open source AI agent for Android that plans, executes and checks tasks on your phone using more than 60 actions and 12 LLM providers.
Why it belongs here. OpenDroid combines autonomous planning, more than 60 Android actions, memory and support for 12 LLM providers in an open source project.
Its limit. It requires highly sensitive permissions, and the dossier includes no independent test confirming the reliability of all advertised automations.
In plain English: give your phone an instruction and OpenDroid attempts to break it into steps, run them across apps and check whether they worked.
Compatibility and setupRequirements and agent differences
Compatibility. Native Android application. Building it requires JDK 21 and Android SDK 35; it uses cloud or local models through supported providers.
Real cost and licenseResource, agent and extra costs
Cost. OpenDroid describes itself as free and open source. APIs, voices and infrastructure have separate costs, but the dossier supplies no verified official euro prices.
Example and alternativeWhen it helps and what else to use
Example. It can plan a routine that looks up information, creates an alarm and prepares a message, once the required permissions have been granted.
Alternative. Tasker and MacroDroid are the alternatives identified in this entry, although the dossier does not support a rigorous price or feature comparison.
Sources and reviewWhat is documented and what was tested
Review. Information checked against the repository, README and official website on 27 September 2026. No independent tests or verified social opinions were supplied.

InteraOne
App
Sources checked: 21 Sep 2026
Customer support with AI and human agents in one inbox, as an open source alternative to Intercom and Zendesk
Open source customer support platform that combines AI and human agents in a single inbox, deployed through Docker or the cloud.
Why it belongs here. It brings AI and human agents, tickets, contacts and multiple channels into an open source platform you can host on your own infrastructure.
Its limit. The dossier contains no independent performance or stability test, and verified total costs officially converted to euros are missing.
In plain English: it gathers questions from your website, email, WhatsApp and Telegram so an AI can respond and a person can pick up the conversation from the same inbox.
Compatibility and setupRequirements and agent differences
Compatibility. Runs as a web service or through your own Docker deployment; it offers an embeddable widget and stated connections to email, WhatsApp and Telegram.
Infrastructure. The stated architecture uses MongoDB, Redis, Qdrant and a compatible LLM provider from OpenAI, Google, AWS Bedrock or Hugging Face. The repository documents starting a development environment, not a production deployment procedure.
Real cost and licenseResource, agent and extra costs
Cost. The core is distributed under Apache-2.0, with an enterprise edition under its own license in /ee. The dossier lists a free Starter plan and two paid plans, but their prices are only in dollars and do not establish the full euro cost of infrastructure, models and maintenance.
Example and alternativeWhen it helps and what else to use
Example. A digital product can bring widget, email, WhatsApp and Telegram queries into one inbox, letting a person take over when needed.
Alternative. Intercom and Zendesk are the listed replacements, but there is no current like-for-like comparison in euros that establishes a winner.
Sources and reviewWhat is documented and what was tested
