pipeless
An open-source computer vision framework to build and deploy apps in minutes
Pipeless
Pipeless is an open-source framework that takes care of everything you need to develop and deploy computer vision applications in just minutes. That includes code parallelization, multimedia pipelines, memory management, model inference, multi-stream management, and more. Pipeless allows you to ship applications that work in real-time in minutes instead of weeks/months.
Pipeless is inspired by modern serverless technologies. You provide some functions and Pipeless takes care of executing them for new video frames and everything involved.
With Pipeless you create self-contained boxes that we call "stages". Each stage is a micro pipeline that performs a specific task. Then, you can combine stages dynamically per stream, allowing you to process each stream with a different pipeline without changing your code and without restarting the program. To create a stage you simply provide a pre-process function…
Key Features:
- Multi-stream Support.
- Dynamic Stream Configuration.
- Multi-language Support.
- Dynamic Processing Steps.
- Highly Parallelized.
- Inference Runtimes Support.
- Well-Defined Project Structure.

Open-source toolkit to build an AI copilot for SaaS products
Open Source alternative to OpenAI Assistants API
🎮 Demo · 🌐 Website · 📚 Docs · 💬 Slack · 🖥 React Components
Superflows makes it easy to add an AI assistant to a software product. This lets users ask questions in natural language and the assistant makes calls to the software's API to answer them.
E.g. a CRM user could ask:
Have we closed any deals with publishing companies? If so, who was involved in those deals?
or:
Eve is ill today. Move her calls to the rest of the team - prioritise those who have had contact with the prospect before.
A user could ask their analytics assistant:
Did the Google Ads campaign we ran last month have a positive ROI? How many conversions did it generate?
Superflows will make API calls to answer these questions or complete tasks, and write code to analyse and plot data.
