Native lightweight API client for macOS

A minimal API debugger for the agent era that never installs plugins or edits your config

Problem

Mainstream API clients like Postman have become bloated and even install plugins and modify configs for Codex/Claude Code in the background, triggering developer backlash. Some want a native, tiny, no-cloud API client that accepts curl pastes, imports collections and does assertions, without disturbing coding agents.

Solution

A native macOS API client with a ~5MB installer: HTTP/SSE/WebSocket in one workspace, all drafts and history stored locally, curl paste and Postman/Bruno collection import, assertion checks; explicitly no plugin installation and no modifying agent configs.

Users

macOS developers using coding agents, privacy-sensitive backend engineers, lightweight-tool enthusiasts.

MVP

HTTP/SSE/WebSocket request panel; curl paste and Postman collection import; assertion checks; local drafts and history; no account, no plugins

Revenue

One-time purchase (~$39) with optional sync subscription; open-source base to drive adoption

Why now

Postman's bloat and config-tampering have caused a trust crisis, and agent workflows need more restrained tools; native macOS utilities are a classic solo-dev niche.
