Instead of Fluxzy
Fluxzy alternatives
Fluxzy records and modifies HTTP/1.1, HTTP/2, and WebSocket traffic, with proxyless capture for apps that ignore system proxy settings. Its rules can change headers, inject authentication, simulate slow networks, and spoof DNS. It also decodes gRPC and Protobuf, inspects OpenAI, Anthropic, and Gemini API traffic, and exports captures in formats including HAR, PCAPNG, cURL, and Fiddler SAZ. Fluxzy works offline without an account or cloud sync, and supports Android, iOS, Linux, macOS, and Windows alongside API and self-hosted use.

Readers may seek a different fit because the free Community edition is for personal use and adds an x-fluxzy-community header; paid licenses remove both limits but are perpetual purchases. Alternatives vary in API testing, traffic rules, mobile workflows, integrations, and whether they offer cloud syncing or local-only handling. Compare platform needs and the particular editing, replay, mocking, and protocol features you rely on, as well as free-tier restrictions and pricing. A tool with a broader API client or a different workflow may suit your work better, even if its traffic capture differs from Fluxzy’s.
