Buoy for Flutter is here (beta)

Updated July 2026

The same in-app devtools + desktop dashboard React Native teams use — now capturing your Flutter app's network traffic. One dependency, pure Dart, no native setup.

What works today

The network inspector ships first. One hook captures everything that rides Dart's HTTP stack — package:http, dio, Image.network, cached images, GraphQL clients — with headers, bodies, timing, status, and errors. It shows up in three places:

  • In your app — a floating devtools bubble with the full network panel.
  • On your desktop — live traffic in Buoy Desktop, side by side with your React Native devices.
  • In your AI editor — Claude Code or Cursor reads your app's traffic through the Buoy MCP server.

Install

flutter pub add buoy

Then wrap your app with one widget — every installed Buoy tool wires itself (HTTP capture, in-app menu, desktop sync, MCP):

import 'package:buoy/buoy.dart';

MaterialApp(
  builder: (context, child) => BuoyDevTools(
    deviceName: 'My App',
    child: child ?? const SizedBox.shrink(),
  ),
)

Pure Dart — no native code, no pods, no gradle changes. Simulators and emulators connect to the desktop automatically; physical devices take one socketUrl pointing at your machine.

What's next

The rest of the Buoy suite — console, storage, and state inspectors for Riverpod, Bloc, and Provider — is being ported tool by tool. Vote on the roadmap to pick the order.

Is this the full Buoy suite?

Not yet — the network inspector is the first Flutter tool. The desktop dashboard and MCP server are the same ones the React Native suite uses, so each ported tool lights up everywhere at once.

What does it capture?

Everything using dart:io's HttpClient: package:http, dio, Flutter's own image loading, cached_network_image, graphql_flutter/ferry. Known gaps: cupertino_http/cronet_http native clients, gRPC, secondary isolates, and Flutter web.

Does it need native setup?

No. The SDK is pure Dart — no pods, no gradle edits. Install, wrap one widget, done.

Is it free?

Free in development, like the React Native tools. Pro unlocks production builds, the MCP server, and unlimited capture with the same license key across both frameworks.
