Coder
Give your coding tool focused project context.
Give a coding tool relevant project context. Developers who want a repository question to carry selected files and an inspectable context receipt.
Full product access for 180 days after activation. No subscription during the trial.
One repository question with a context receipt

Context receipt
Selected files sent on this visible user turn.
Local workspace Coder
One repository, one question, one receipt
Ask where a function is defined. Open the receipt to see the selected files. That is how you know the request went through Coder.
- 01
Install
Create a dedicated environment, install the pinned Coder package, then run init.
- 02
Connect a tool
Use a supported editor or terminal path. Coverage is not identical for every host.
- 03
Ask with a receipt
Ask one repository question and open the context receipt for that turn.
Context receipt for a visible user turn
Coder records what was retrieved, what was sent, and how that compares with a session-start counterfactual on the first eligible invocation. Auxiliary model calls are excluded from the input-savings total.
Works in IDEs, VS Code shims, and the terminal
Coder connects through MCP, an OpenAI-compatible harness, or the VS Code extension. The extension also loads in VS Code shims such as Cursor and Windsurf. Native tab-complete and some closed Composer paths are partial, and we label them that way.
VS Code and VS Code shims
The VS Code extension runs in VS Code and in forks that load VS Code extensions, including Cursor and Windsurf.

What it does
- Connect a repository and route focused context into a supported coding tool
- Context integration is separate from provider routing
- A context receipt shows selected files and eligible requests that passed through Coder
- Controlled token example: 81.4% less input against a stated session-start baseline, four test turns
Prerequisites
- Python 3.10 or newer
- Windows x64, Linux x86_64 with glibc 2.28 or newer, or macOS 15 on Apple silicon
- A supported coding client you already use
Supported connections: VS Code (extension), Cursor (VS Code shim), Windsurf (VS Code shim), Claude Code (terminal agent), Aider (terminal agent), JetBrains AI (IDE)
Data handling
The primary indexes and source processing run on your device. Account services and selected bounded policy decisions use MemStrata services. A cloud reader or destination receives the content needed for the connection you choose. Credentials are stored in the operating-system credential vault. Customer content is not used for training unless the customer separately opts in.
| Feature | Local material | Possible outbound | Trigger | Credential location |
|---|---|---|---|---|
| OAuth, signed entitlements, and device registration | Device and entitlement cache | Identity and device-bound entitlement fields | Sign-in or refresh | Operating-system credential vault |
| User-selected cloud model or connector | Local evidence selection and indexes | Only the data required for that explicit operation | User configures and sends the request | Operating-system credential vault |
| MemStrata-managed email | Local alert or report draft | Minimized message and recipient | User-configured delivery; one message per signed-in user per UTC day during trial | Server secret plus entitlement |
| Project indexing and context routing | Repository indexes, context receipts, and local telemetry | Selected context to a user-chosen coding model or MCP client | Editor or terminal request after the user connects a tool | Operating-system credential vault for model keys |
Install
Install MemStrata on Windows, Linux and Apple silicon
Full product access for 180 days after activation. No subscription during the trial.
Detected choices are a suggestion only. A browser cannot reliably know your macOS version or whether Python is installed.
Python 3.10 or newer is required. On Windows, if Python is missing, install it from python.org/downloads/windows and open a new terminal.
Microsoft Store Python redirects LocalAppData writes. The Windows command follows the real environment path after venv so pip is not pointed at an empty folder.

FAQ
Do I replace my editor?
No. Coder sits beside the coding tool you already use. You connect a supported client rather than switching editors.
How do I know a request went through Coder?
Open the dashboard or context receipt for that visible user turn. A green tray icon alone is not proof that a prompt was routed.
Why is the tray green but the dashboard empty?
The tray can show that Coder is running while no eligible visible user turn has been recorded yet. Send a prompt through a connected client, then refresh the dashboard.
What happens if I uninstall while a client is routed through it?
The client may fail to reach the model until you restore its previous provider settings. Uninstall instructions cover returning those settings.
Is the 81.4% figure typical for every developer?
No. It is a controlled example with four eligible visible turns and a stated session-start baseline. Results vary by repository, client, model and task.
