About

Test Mace is a modern powerful crossplatform tool for working with an API and creating automated API tests. Create requests and scenarios using variables, authentication, autocomplete feature and syntax highlighting. Build complex scenarios using our convenient and simple UI interface. Perform full regression testing with just one click. Assign a request result to a variable and get access from other nodes. Save authorization tokens, response headers or parts of a response body. Run your scenarios in different environment contexts. Use this to organize development, stage and production environments. Embedded authentication methods will help you to do authentication if you use one of the most popular types. You can use quick share feature to share your request with colleagues. Just press a button to copy a specific node's url. All that you need now is to send this url to your teammate.

About

Twigg is a context-management tool designed for long-term interactions with large language models that replaces linear chat threads with a visual, branching tree of conversation nodes, giving users control over what context is sent to the model. You can explore alternate directions by instantly creating new branches from any point, cutting or copying nodes, deleting or moving content to optimize the prompt context, and thus improve performance while managing complexity. The interface provides a dashboard tracking token usage per model and shows credit consumption transparently. By controlling context at the node level, Twigg helps reduce unnecessary tokens and supports the concurrency of ideas without cluttering your main workflow. Compatible with major models (via BYOK support) and designed for extended projects, Twigg essentially acts as “Git for LLMs”, enabling versioning, branching, and precise context management for conversational AI workflows.
