Edgee Codex Compressor is an open-source Rust-based AI gateway that sits between your coding agent (Claude Code, OpenAI Codex, or any LLM client) and the API. It losslessly compresses tool call results, file reads, shell outputs, and other large context payloads before they hit Anthropic or OpenAI's token counters — extending your effective context window by an average of 26-35% without changing any outputs. The core insight is that most of what fills context windows in coding agents is repetitive: boilerplate file content, repeated error messages, verbose JSON responses, and tool output that could be summarized without information loss. Edgee intercepts these at the gateway level, applies a combination of deduplication, semantic compression, and caching, then decompresses before passing to the model so the LLM sees full fidelity content. For developers regularly hitting Claude Code Pro session limits, this is a practical workaround. No code changes, no API key swapping — just point your coding client at the local Edgee proxy. The full source is on GitHub under the Edgee organization (the same team that builds Edgee, the analytics and CDN privacy gateway).

MemPalace is a free, MIT-licensed AI memory framework that stores LLM conversation data verbatim locally — no AI summarization step, no per-query API costs. It integrates with Claude Code, ChatGPT, and Cursor via MCP, and claims the highest LongMemEval benchmark score among free memory frameworks at 96.6% (initially claimed 100% before community pressure forced a correction after GitHub issue #29 exposed test-set tuning). The project went viral on GitHub with 23,000+ stars in under 48 hours, partly because it was built by actress Milla Jovovich and developer Ben Sigman — an unusual origin story that dominated early coverage. But the technical pitch is real: competing paid solutions (Mem0 at $19–249/month, Zep at $25+/month) do similar things and charge for the privilege. MemPalace runs fully local, connects to any POSIX filesystem, and the verbatim storage approach avoids hallucination artifacts introduced by AI-summarized memory. The catch: verbatim storage means much higher storage overhead than summarization-based approaches, retrieval latency grows with context size, and the benchmark controversy raised questions about the team's methodology. For personal projects and small teams, the zero-cost angle is hard to argue with. For production systems where memory quality is critical, wait for independent benchmarking.
Reviewer scorecard
“Any tool that gives me 30% more context for free is worth running. A local Rust proxy adds minimal latency and the implementation is auditable — I can verify it's actually lossless. If the compression holds up on larger codebases this is an immediate install for me.”
“Zero API cost memory is the killer feature here. I was paying $40/month for Mem0 to give my coding agent project context — MemPalace does the same thing for free and runs entirely local. MCP integration works cleanly with Claude Code and Cursor out of the box.”
“'Lossless' semantic compression is a contradiction in terms — any summarization involves decisions about what's important. Running all your API traffic through a third-party proxy also raises data handling questions. The GitHub repo is young and I'd want a full audit before trusting it with proprietary code.”
“The benchmark controversy is a red flag — the team claimed 100% on LongMemEval but was caught tuning on the test set. Verbatim storage also means no noise reduction and exponential storage growth. At 23k stars in 48 hours this smells more like celebrity hype than technical validation. Wait for independent benchmarks.”
“Token efficiency layers between clients and APIs are an inevitable part of the AI infrastructure stack. Edgee is building in the right place — the gateway, not the model or the client. As context windows grow, intelligent compression becomes more valuable, not less.”
“Persistent AI memory is going to be a core primitive for every personal AI system. MemPalace democratizing it with zero cost and local storage is the right direction — this is infrastructure that should be free. The benchmark mishap will be forgotten if the product performs in the real world.”
“Unless you're running coding agents, the token compression use case doesn't map to creative workflows where you want the model to see the full richness of your prompts. For most content work, the complexity of running a local proxy outweighs the marginal gains.”
“My AI assistant finally remembers my brand guidelines, preferred tools, and ongoing projects without me re-explaining them every session. Free, local, and no terms-of-service anxiety about where my work is going. Exactly what the creative workflow needs.”
