Fusebox v0.5.1

The streaming, caching, and binary-efficiency update, with the TLS dependency patched before publication. The v0.5.0 tag was retained without publishing a release after the dependency audit found newly published Rustls advisories.

Changes

• Update Rustls to 0.23.46, addressing RUSTSEC-2026-0346, RUSTSEC-2026-0347, RUSTSEC-2026-0348, and RUSTSEC-2026-0349.
• Scan fragmented SSE lines once. A synthetic 4 MiB event in 16 KiB chunks decoded in 1.875 ms versus 123.169 ms before; ordinary proxy latency and provider generation speed are unchanged.
• Embed compressed dashboard text and omit unused SQLite full-text/spatial modules. Matching Linux builds measured a 4.96% smaller executable; the ten dashboard text assets transfer 71.6% fewer bytes with gzip. ETags and conditional requests avoid downloading unchanged assets. These measurements precede the Rustls patch.
• Add optional client/workspace cache-key scopes, namespaces, incompatible-hint policies, and requested/applied diagnostics across HTTP and native Codex WebSockets. Caller keys, client isolation, account affinity, and session-scope defaults are preserved.
• Avoid redundant copies in request translation, response parsing, and continuation history; reduce time holding the routing lock.
• Add optional HTTP body, concurrency, and aggregate decoded-body limits, with permits held through response completion or cancellation. Aggregate admission remains unlimited by default.
• Cache Docker dependencies separately from application/UI changes and cache release build outputs by target.
• Match Claude Code 2.1.299 in the default client identity.

See the implementation report for measurement methods and limits, and the configuration reference for the new settings.

Fusebox v0.4.0

The first release of Fusebox: one fast binary that turns your Claude, ChatGPT, Gemini, Antigravity, Grok, Kimi, Meta, Devin and Vertex accounts into OpenAI, Anthropic and Gemini compatible APIs, with a dashboard built in.

Fusebox grew out of CLIProxyAPI-Rust by @IuCC123 and carries on from its v0.3.2. Everything you set up for CLIProxyAPI-Rust or CLIProxyAPI keeps working.

Highlights since v0.3.2

• Usage and costs. A Usage page records the tokens every request used, can import opted-in Claude Code and Codex histories (also from a collector on another machine), and estimates what that would cost at API list prices. Named clients give each tool its own key, so you can see which tool sent what.
• Smart quota balancing. routing: smart-quota sends new sessions to the account whose weekly limit renews first, so allowance that would expire unused gets used, while a 5-hour reserve protects sessions that are already running.
• Better prompt caching. Conversations without a session id are recognised by their first message and stay on one account, and ChatGPT, OpenAI and xAI get a stable cache key.
• A rebuilt dashboard. New design, a command palette (Cmd/Ctrl K), a phone layout, a Models page, live account activity, a settings editor alongside the YAML file, and setup snippets for Claude Code, Codex, the OpenAI SDK and curl under Config, Clients.
• Installable app with push notifications. Over HTTPS the dashboard installs as an app and can notify you when a sign-in expires or a provider runs out of capacity.
• New models without a release. Claude and Codex accounts fetch their model lists from the provider, and the Models page can add any other model by hand.
• Current client identities. Requests match Claude Code 2.1.296, Codex CLI 0.162.1, Grok Build 1.0.50, Muse Code 1.4.4, Devin CLI 3000.11.3 and Antigravity 2.22.0, and a daily check opens an issue when one of them falls behind.
• Banked resets (opt-in): see and use the limit resets your Claude and ChatGPT subscriptions have banked.
• Management API: GET /api/faults, a faults event on /api/live, and ongoing sessions in load events.
• Fixes: token accounting when a client closes a finished stream, adaptive thinking across Claude tool turns, idle Codex WebSockets (thanks @dr-baker), compressed request bodies, and faster streaming with per-account connection pools.

Download the archive for your platform below, extract it and run ./fusebox. Then open http://127.0.0.1:8317 and connect an account.

Platform	Archive
macOS, Apple Silicon	fusebox-…-aarch64-apple-darwin.tar.gz
macOS, Intel	fusebox-…-x86_64-apple-darwin.tar.gz
Linux, x86_64	fusebox-…-x86_64-unknown-linux-gnu.tar.gz
Linux, ARM64	fusebox-…-aarch64-unknown-linux-gnu.tar.gz
Windows, x86_64	fusebox-…-x86_64-pc-windows-msvc.zip

SHA256SUMS lists every archive's checksum, and each archive has a build attestation you can check with gh attestation verify <archive> -R DigitalPals/Fusebox.

Or run the ghcr.io/digitalpals/fusebox image (amd64 and arm64) as the quick start shows, or build it with Rust 1.88 or newer: cargo install --git https://github.com/DigitalPals/Fusebox.

The binaries are not code-signed. If macOS refuses to open it, run xattr -d com.apple.quarantine fusebox once.

Upgrading from CLIProxyAPI-Rust

• The binary is now fusebox and the image ghcr.io/digitalpals/fusebox.
• auth-dir defaults to ~/.fusebox, but ~/.cli-proxy-api is used when only that one exists.
• The CLIPROXYAPI_RUST_* variables and x-cliproxy-* request headers still work. The response header naming the account is now x-fusebox-account (was x-cliproxyapi-rust-account).

See the README for configuration, endpoints and coming from CLIProxyAPI.
