Your editor, terminal, Git, and AI assistant — in one workspace.

A Windows IDE built on Code - OSS, with Xynapse Assistant and BVC planning included.

Download

Two releases, one project. Choose the complete IDE or add the assistant to a compatible VS Code editor.

The IDE 1.108.0 installer still includes Assistant 1.0.0; install the new VSIX to update it to 1.0.1. See release verification and known limits. Each release provides SHA256SUMS.txt; Windows executables are currently unsigned.

Quick start

Complete IDE

1. Run the installer, or extract the portable ZIP into a new folder and launch Xynapse.exe.
2. Open your project folder.
3. Configure a model in Assistant. For Yandex Cloud onboarding, enter your API key and folder ID, then select a model.
4. Attach a file or select code, choose a mode, and describe your task.

Standalone extension

1. Download the VSIX from the table above.
2. In your editor, open Extensions → Install from VSIX…, select the file, and reload the window.
3. Open Xynapse Assistant and configure your model provider.

Yandex configuration also supports YANDEX_API_KEY and YANDEX_FOLDER_ID. See the bundled configuration template. Model usage is billed by your selected provider.

Work with your code

• Bring project context. Attach files, folders, diffs, diagnostics, selected code, and terminal output; use indexed codebase search for wider context.
• Review changes in the editor. Ask for an inline edit or let the agent make changes you can inspect in Source Control.
• Choose models by role. Configure chat, editing, and autocomplete independently.
• Connect tools. Use workspace tools and configured MCP servers with compatible models.
• Plan with several perspectives. Council and BVC collect proposals and critiques before implementation.

BVC planning

BVC 0.1.0 coordinates independent proposals, targeted critique, and a final plan within a model-call budget. Attach relevant files or select code, then try:

/bvc easy Fix the parser regression
/bvc medium Plan the authentication refactor
/bvc hard Compare migration approaches across services

The result is saved to bvc-plan.md. Optional discussion logging adds bvc-discussion.md with proposals, objections, and a call trace. You can also choose roles, models, and a budget through the BVC button.

The plan still needs implementation and tests. Read the Assistant guide or explore the standalone BVC core.

Release checks

The September 5, 2026 build passed installation, isolated-profile startup, extension activation, and uninstall checks. All 405 extension files match the pinned VSIX in the installed IDE and portable archive. TypeScript, targeted ESLint, and 131 build tests passed; all 8 published assets were downloaded again and their SHA-256 hashes matched.

See the release verification report for the full scope and limitations, including the separately dated browser-test results.
