Publish, subscribe, and send request-reply calls from a visual client — then automate the same flows via CLI or let an AI agent scaffold them for you.
Built into the Qaze desktop app
Publish messages, subscribe to subjects, and fire request-reply calls — all from a visual interface. Inspect payloads, tweak headers, and iterate on your messaging flows without writing a single line of code.
Send messages to any subject with custom JSON or binary payloads, headers, and reply-to addresses.
Listen on subjects and wildcards in real-time. Incoming messages stream into a searchable, filterable list.
Fire a request and see the response inline — with configurable timeouts and full header inspection.
Organize your frequently used messages into collections. Save, share, and re-send them with one click.
Run manifests from the terminal
Export your collections as manifest files and run them headlessly via the Qaze CLI. Replay the same messaging sequences in CI/CD pipelines, smoke-test deployments, or automate repetitive publishing workflows — no GUI required.
Declarative YAML files that describe a sequence of publish, subscribe, and request-reply operations.
Run any manifest from the terminal with a single command. Structured output shows exactly what happened.
Plug into GitHub Actions, GitLab CI, or any pipeline to validate your NATS setup on every deploy.
Check manifest files into your repo next to your application code. Review messaging changes in pull requests.
Generate manifests with AI
Use the Qaze skill for coding agents to scaffold NATS manifests from natural language. Describe the messaging flow you need and get a ready-to-run manifest in seconds — then execute it via the CLI or import it into the GUI.
Describe your messaging scenario in plain English. The agent produces a complete, valid manifest file.
Generates well-structured YAML manifests you can run immediately or fine-tune before executing.
Works inside Claude Code, Cursor, Windsurf, and other AI-powered development environments.
Generate, run, adjust, and re-run — shorten the feedback loop when building NATS-powered services.
