Headroom
A token compression plugin for AI coding tools designed to reduce token consumption in AI API calls and lower associated costs.
Timeline (last 90 days)
Headroom relies on the local network or correct port forwarding settings, and using it across networks may require some networking knowledge.
Headroom's lack of an account system means settings cannot be synced across devices, and each device must be configured separately.
Headroom does not rely on an intermediary server, so it cannot automatically perform NAT traversal, and users need to manually set up port forwarding or use solutions such as a VPN.
Headroom is a screen-sharing product that received 70 votes of support on Product Hunt.
Headroom focuses on a screen-sharing experience that requires no additional software installed on the Mac, no account creation, and no intermediary server.
Headroom uses macOS's built-in screen-sharing protocol, so users do not need to install any additional software on their Mac.
According to developer Haru, Headroom requires no account creation, data does not pass through third-party servers, and all connections are established directly between devices.
Headroom has adapted to the foldable-screen characteristics of the iPhone Duo: when the device is in a half-folded state, the upper half displays the Mac desktop, and the lower half becomes a virtual keyboard and trackpad.
Headroom's interface adjusts dynamically as the folding angle changes, for example restoring full-screen display when fully unfolded and switching to a compact mode when folded.
Headroom has not yet provided detailed performance benchmark data, and actual compression results may vary depending on data characteristics.

Headroom is a context compression layer designed specifically for AI Agents, sitting between the application and model providers, compressing tool outputs, log files, and other data before the content is sent as billable input tokens.

50%UnverifiedHeadroom's compression strategies include removing redundant whitespace in JSON, merging duplicate key-value pairs, and compressing repeated patterns in logs.
50%UnverifiedWhen run as an MCP server, Headroom can automatically perform compression before tool results are returned to the model, fully transparent to the upper-layer application.

50%UnverifiedSome metadata (such as timestamp ordering and nesting levels) may be useful for specific reasoning tasks, and although the answers after compression are "the same," it is hard to cover all scenarios, so developers should run A/B validation on their own data.
50%UnverifiedHeadroom offers three ways to use it: integrated into code as a library, as a proxy that intercepts requests, or run as an MCP server.
50%UnverifiedHeadroom's compression is semantic-aware; unlike the byte-level lossless compression of general-purpose text compression tools (such as gzip), it is lossy but task-lossless.
50%UnverifiedHeadroom is an open-source project that compresses tool output, logs, files, and RAG chunks before they enter the LLM, in order to reduce token counts.
50%UnverifiedAccording to the project description, Headroom can reduce token counts by 20% for coding agents.
50%UnverifiedAccording to the project description, Headroom achieves compression rates of up to 60-95% on JSON data while keeping answer quality unchanged.
50%UnverifiedHeadroom is implemented in Python.
