About

Headroom is a menu bar app for macOS, Windows and Linux that cuts Claude Code and ChatGPT Codex token costs by ~50%, which can translate to up to 2x as much usage on the plan you already pay for. It compresses the bulky tool output, logs and boilerplate your coding agent sends. Compression runs locally, before the request leaves your machine, so prompts and code stay private. Source code passes through untouched, and the originals stay available to the agent through a retrieval tool. Typical coding sessions save 25-50% overall. Across 183 Claude Code users over one week, Headroom cut input tokens by 34% (measured) and output tokens by 33% (estimated). Also included: a dashboard and activity feed with tokens and API-equivalent dollars saved, project learnings that turn past sessions into token-saving rules, and one-click add-ons (MarkItDown, Serena, Codebase Memory, Context7, Ponytail, Caveman). 7-day free trial, no credit card. Plans from $3/month.

About

Subspace is an AI-native agent workspace designed to help developers and teams manage, coordinate, and collaborate with multiple coding agents in a single unified environment while preserving context across sessions. Instead of treating each AI interaction as isolated, the platform builds persistent memory in the background by compressing every conversation into structured observations such as decisions, blockers, and progress, which are continuously synthesized into a clear, evolving project state. This shared memory belongs to the workspace rather than any individual tool, allowing different agents like Claude Code, Codex, or others to seamlessly pick up where previous sessions left off without requiring repeated explanations or manual context transfer. Subspace integrates terminals, files, documentation, browser views, and git workflows into organized workspaces, enabling users to run multiple agents side by side and switch between projects almost instantly.
