The free API client that keeps your work private: no accounts, no subscriptions, no lock-in. Your work in a safe harbor that you control.harborclient.comJoined June 2026
Everyone I know who started using AI loves it, but it's damn hard getting people to try it. Some of those who've come to depend on AI might even pay a small subscription price. Small being a very important word.
When you just want to test localhost:8080/ping but your API client demands a login, a cloud workspace, and a blood sacrifice. 🩸 Meet HarborClient: Just open the app and send the request. ⚓️ buff.ly/53vS1BN
How to Use Environments in HarborClient
Environments let you swap request variables between dev, staging, and prod without duplicating collections—import from .env files, export for sharing, and use merge/copy down to keep them in sync.

How to Use Tab Groups in HarborClient
Tab groups let you save a set of related request tabs and reopen the whole workspace with one click—perfect for recurring API workflows.

You built a great API. Testing it shouldn’t turn into another monthly bill.
HarborClient is free, open-source, and made for developers who want control over their workflow.

HarborClient should feel like your workspace, not someone else’s.
Plugins let you extend the client around the way you build. Themes let you keep the interface comfortable while you work.
Small pieces. Clear control.

API testing shouldn’t trap your workflow.
HarborClient is built around developer control: Git-friendly workflows, self-hosted team databases, and an open-source foundation you can actually extend with plugins and themes.
No maze. No lock-in. Just clearer API work.
Create a HarborClient Marketplace Theme with the Theme Designer
Learn how to design a theme in HarborClient’s Theme Creator, package it as a GitHub plugin with a manifest, and submit it to the HarborClient marketplace catalog.

A big part of HarborClient’s direction is keeping the architecture approachable.
Electron + React makes that possible:
desktop app experience, familiar frontend patterns, and room for contributors to build on top of it.
@AhnafSMuiz It's annoying when you're a dark mode user and you open apps that blind you with lightness. So yeah, I'd prefer most apps have light and dark mode.
AI coding assistants are great, but you shouldn't have to pay a premium subscription just to use them in your API client. Plug your own local API keys into HarborClient and chat with your responses. 🤖⚓️
