Open-source engineering calculators for civil and structural design
Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub.
Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.
Registered users get calculation workings, bending/shear/deflection diagrams and PDF export.
Four project-based pathways in Python, AI for construction, AI governance and building AI agents.
Build, train, and deploy computer vision for the physical world
Label thousands of images in minutes using frontier models and custom filters, then curate datasets for training.
Combine detection, tracking, and logic blocks to orchestrate actions, update databases, and connect to industrial systems.
Run high-speed inference in the cloud or on edge devices, processing live video and images wherever the application lives.
Get into production quickly with an agent that sees the world, understands what is happening, and triggers actions.

SpecialistRun, fine-tune, and deploy machine learning models with one line of code

Free / Open-sourceFocuses specifically on the YOLO model family for real-time object detection, whereas Roboflow offers a broader suite of annotation and dataset tools.


Provides powerful enterprise data labeling and curation workflows, but lacks Roboflow's built-in model training and edge deployment pipelines.
Free / Open-sourceSearch and study millions of public SKILL.md agent skills

Combines annotation and data curation for enterprise ML pipelines, but requires more manual setup for edge model deployment.
Free / Open-sourceFree practical deep learning courses, research and open-source libraries
Strong multimodal data infrastructure for physical AI datasets, though less focused on simple end-user model deployment than Roboflow.

Free / Open-sourceOpen-source database of AI models, prices and capabilities
Free / Open-sourceFree open course for prompt engineering and AI security

Free / Open-sourceA flexible open-source labeling tool you can self-host, but lacks Roboflow's managed cloud infrastructure for training and deployment.
