Context Mode

open-source plugin · commercial platform · 287,000+ developers

The other half of the context problem — for developers and for engineering orgs. An MCP plugin that keeps raw data out of the LLM context window. A Platform that surfaces what your team is doing with the saved tokens. Same engine, two surfaces, your choice.

context-mode keeps raw data out of the LLM context.

Your AI coding agent burns through context. Every gh issue list, every grep, every file read piles into the conversation and gets re-sent every turn. Fifty turns in, that one command has cost you 750,000 input tokens.

context-mode is an MCP plugin that intercepts large tool output before it touches context. Raw data goes into a local FTS5 store. The agent searches it when it needs to. Same answers. Same work. 30× fewer tokens.

Works on 15 platforms — Claude Code, Cursor, Copilot, Codex, Gemini CLI, JetBrains Copilot, Kiro, and 8 more. 287,000+ developers run it locally today.

Full story · Context Saving → View on GitHub

You're already saving money. Reinvest a fraction of it here.

Your team is already running context-mode on every machine. Every session saves up to 98% of context per call — real budget back in your pocket, every day, on every developer. The OSS plugin pays for itself before lunch.

Context Mode Platform takes a small slice of those savings and turns the plugin's existing data into an org view your CTO, EM, and CISO can defend. You're not adding a new tool — you're activating a layer that's already there.

How the data flows

The OSS plugin already captures structural events on every tool call — tool name, file path, error counts, decisions made. Locally, in a SQLite store on the developer's machine. This is happening right now, for free, whether you're a Platform customer or not.

When you opt into Platform, those same events forward to your private org workspace over an authenticated channel. Never source code. Never prompt content. Never file content. Just the structural metadata your engineers' workflow already generates. One switch, no new install, no developer interruption.

01
Connect
Your team is already running the plugin. One opt-in switch — same workflow, no disruption. Onboarding takes a single command.
02
Protect
Your code, prompts, and IP never leave your machines. Only structural metadata — tool names, error counts, file paths — reaches the Platform.
03
Detect
Pattern detection runs continuously — capacity imbalance, error spikes, rework concentration, blockers your engineers can't see. By Monday morning, the findings are waiting.
04
Answer
Your CTO sees the ROI. Your EM sees who's stuck. Your CISO sees the audit trail. Same data layer, three different conversations — no one has to translate.

§ 04 · How it fits together

One engine, two surfaces, many Solutions.

The OSS plugin is the entry point. The Platform is what you opt into when you want the org view. Solutions are what you actually buy.

Dev surface · Free
$context-mode

The plugin. Runs locally. No account, no cloud, no network. The free workflow 287,000+ developers ship code with every day.

Org surface · $20/seat
Context Mode Platform

The commercial umbrella. Hosts Solutions. Opt-in event forwarding from the same plugin — one switch, no new install.

Privacy boundary stays where it should: the plugin only emits structural events — tool name, file path, error counts — never prompt content, never source code. The OSS plugin you ship with stays free forever. The Platform is what you choose if you want the org view.


One name. Two surfaces. Your call.

If you're a developer — install the plugin. It's free, local, and quiet. Three commands and you're saving tokens. If you're an engineering org — open the Platform and see what your team is doing with the saved tokens.
