Vast.ai

freemium

4.1 / 5.0

Vast.ai is a decentralised GPU marketplace that connects AI researchers and developers with GPU compute sourced from a global network of independent providers - including data centres and individuals with spare GPU capacity - at prices significantly lower than traditional cloud providers. Users can search, filter, and rent GPU instances by price, location, reliability score, and hardware specifications, making it one of the most cost-practical options for AI training and inference. Vast.ai supports Docker-based workloads and offers both on-demand and interruptible instance types.

Best for: Cost-conscious AI researchers, hobbyists, and startups who prioritise price over guaranteed uptime for training and experimentation.

4.5 / 5.0

Aider is an open-source AI pair programmer that runs in the terminal, enabling developers to make changes across multiple files in their local codebase using Claude, GPT-4, or other LLMs. It tracks file changes with git commits, understands the full repository structure, and executes complex multi-file refactors from natural language instructions. Aider is popular with developers who prefer terminal-based workflows.

Best for: Developers who prefer terminal-based workflows and want AI to make multi-file changes across their codebase with automatic git commits
