Label Studio is an open-source data labeling and AI evaluation platform from HumanSignal. It handles images, video, audio, text, documents, time series and agent traces in one flexible workspace, and connects to your ML pipeline through an API, Python SDK and webhooks.

Postman is an API platform that covers the whole API lifecycle, from designing and testing endpoints to documenting, monitoring, and governing them at scale. Its newer agent-focused features let coding assistants and AI agents run collections, generate tests, mock endpoints, and query a structured Context Graph of your organization's APIs, so automation stays grounded in how your APIs actually behave.

Label Studio is an open-source data labeling and AI evaluation platform from HumanSignal. It handles images, video, audio, text, documents, time series and agent traces in one flexible workspace, and connects to your ML pipeline through an API, Python SDK and webhooks.
Programmable interfaces and custom templates let one workspace handle images, video, audio, text, PDFs, time series and multi-modal tasks.
Build custom benchmarks and rubrics, run side-by-side model comparisons, and grade generated answers against retrieved sources for RAG evaluation.
Collect human preferences, corrections and rankings to feed reinforcement learning from human feedback and fine-tuning workflows.
Connect observability tools, storage and any model to power AI-assisted pre-labeling, benchmarking and continuous evaluation.

Its newer agent-focused features let coding assistants and AI agents run collections, generate tests, mock endpoints, and query a structured Context Graph of your organization's APIs, so automation stays grounded in how your APIs actually behave.
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.
