A Personal Engineering Showcase·

I built an APIclient to killthe giants.

Tired of bloated Electron apps and slow load times, I engineered FluxPort from the ground up — natively on the web. Sub-100ms, local-first, breathtakingly fast.

Engineering Breakdown

Built to replace

the giants.

Postman. Insomnia. Paw. They ship entire Chromium processes just to render UI. FluxPort runs in the browser you already have.

The Old Way

Electron Apps — Postman, Insomnia

Bundle entire Chromium instances. 500MB+ install, 3–5s cold start, constant cloud sync of your private keys.

The FluxPort Way

Next.js 15 + Native Web APIs

Zero install. Powered by Next.js App Router, styled with Tailwind v4 OKLCH, and Redux Toolkit. Sub-100ms cold starts.

fluxport — terminal

Core Capabilities

Everything you need.

Nothing you don't.

Redux Architecture

Complex nested state for Workspaces, Environments, and Collections—isolated via surgical slice logic.

GraphQL + REST

Dual protocol engines. Pivot between structured REST and GraphQL schema-aware execution seamlessly.

Radix Primitives

Accessible, unstyled building blocks—Dialogs, Dropdowns—assembled into a native desktop feel.

Local Persistence

No backend required. Robust localStorage sync ensures every header and script survives page reloads.

AES-256 Encryption

All workspace settings encrypted before touching your disk. Tokens never leave your machine.

Sub-40ms Latency

Zero-overhead parsing. FluxPort handles 10MB+ payloads at buttery-smooth 60fps without flinching.

01 / DYNAMIC ENVIRONMENTS

Smart Variable Binding.

Define {{BASE_URL}} once and toggle your entire app context between Local, Staging, and Production in one click.

✓
Global & Local ScopesVariables scoped to workspaces — credential leaking is impossible by design.
✓
Real-time ResolutionSee exactly what value will be injected as you type in the URL bar.

02 / GRAPHQL NATIVE

First-Class GraphQL.

A dedicated GraphQL engine with query auto-completion, live schema introspection, and a split-pane operation view baked in.

✓
Live Schema BrowsingPoint FluxPort at any endpoint and it parses the entire documentation tree instantly.
✓
Variable InjectionDedicated JSON panes for isolated query variable testing and mutation input.

Query

query GetUsers {
users {
id
name
email
}
}

Response

{
"data": {
"users": [
{ "id": 1,
"name": "Alice" }
]

Roadmap

What's coming next.

Phase 1 · Released

Local Client — Complete

Complete rewrite of the core Request/Response engine and UI from the ground up.

Phase 2

WebSocket Support

Bidirectional streaming — WS, Socket.io, SSE connections.

Phase 3

AI Mock Generation

Using local LLMs to auto-generate exact JSON response mocks from schema definitions.

Phase 4

Team Collaboration

Real-time multiplayer editing with CRDT conflict resolution and RBAC.

Security First

Your data never
leaves your side.

FluxPort was born from frustration with cloud-syncing clients that store your API paths and tokens on their servers.

AES-256 Storage

Workspace settings encrypted before touching disk.

Zero Cloud

No database of your requests — ever.

Local Keys

RSA pairs generated locally in kernel keychain.

Open Source

Every line auditable. No hidden telemetry.

security — console

$ fluxport security --init

Generating RSA-4096 keypair...

✓ Keys secured in kernel keychain

Enabling AES-256-GCM storage...

✓ All workspace data encrypted

✓ Zero cloud sync — verified

Security audit: PASSED ✓

"Code is poetry when every
cycle is accounted for."

FluxPort isn't a venture-backed product. It's an obsession — a statement that developer tools should be fast, private, and breathtakingly beautiful.
