A patched build of Claude Code CLI (v2.1.88) with all telemetry, analytics, and phone-home behavior removed.
One binary. No telemetry. Drop-in replacement.
Download claude-private-2.1.88.run from Releases, then:
chmod +x claude-private-2.1.88.run
./claude-private-2.1.88.runPass --prefix /custom/path to install somewhere other than ~/.local/bin/.
The binary is self-contained (Bun executable). No dependencies. Runs on any Linux x86_64 system.
claude-private # interactive session
claude-private -p "explain this code" # non-interactiveAll standard claude flags work (-p, --model, --allowedTools, --add-dir, etc.).
Claude Code speaks the Anthropic Messages API (POST /v1/messages). If your backend speaks a different protocol (OpenAI, vLLM, Ollama, etc.), use claude-code-router to translate, then point at it:
ANTHROPIC_BASE_URL=http://localhost:3456 claude-privateThe stock Claude Code CLI contains 17+ phone-home mechanisms, many firing on background timers even when you're idle:
| Mechanism | How often it fires | Destination |
|---|---|---|
| Datadog event logging | Every 15 seconds | http-intake.logs.us5.datadoghq.com |
| 1st-party event logging | Batched periodic | api.anthropic.com/api/event_logging/batch |
| BigQuery metrics export | Every 5 minutes | api.anthropic.com/api/claude_code/metrics |
| GrowthBook feature flags | Periodic refresh | GrowthBook remote eval |
| Remote managed settings | Every 1 hour | api.anthropic.com/api/claude_code/managed_settings |
| Policy limits polling | Every 1 hour | api.anthropic.com/api/claude_code/policy_limits |
| User settings sync | Background | api.anthropic.com/api/claude_code/user_settings |
| Metrics opt-out check | Background (24h cache) | api.anthropic.com/.../metrics_enabled |
| Session transcript ingress | During conversations | api.anthropic.com/v1/session_ingress/ |
| MCP registry prefetch | On startup | api.anthropic.com/mcp-registry/ |
| Bootstrap API | On startup | api.anthropic.com/api/claude_cli/bootstrap |
| Grove API | Background | api.anthropic.com/api/claude_code_grove |
| Referral eligibility | Background | api.anthropic.com/.../referral/eligibility |
| Trusted device enrollment | After login | api.anthropic.com/api/auth/trusted_devices |
| API preconnect warmup | On startup | HEAD request to API |
| Plugin auto-updates | Background | Remote marketplaces |
| Background housekeeping | Various timers | Magic docs, skill improvement, etc. |
All removed. The Claude API endpoint for actual conversations (POST /v1/messages) is untouched.
Layer 1 — Binary patching. All telemetry URLs in the compiled executable were replaced with same-length dummy strings. The Datadog client token was zeroed out. Binary size unchanged, no structural modifications.
Layer 2 — Environment overrides. The wrapper script sets:
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
DISABLE_TELEMETRY=1
DISABLE_AUTOUPDATER=1
CLAUDE_CODE_ENABLE_TELEMETRY=0
OTEL_METRICS_EXPORTER=none
OTEL_LOGS_EXPORTER=none
OTEL_TRACES_EXPORTER=none

# Patch a new binary
python3 patch_binary.py /path/to/new/claude ./claude-notelemetry
# Rebuild the .run installer
bash make-run.shpatch_binary.py does same-length byte replacement on 15 URL patterns. If Anthropic changes their telemetry endpoints in a future version, you may need to update the patterns.

- Linux x86_64 only — compiled Bun executable.
- No auto-updates — disabled by design. Re-patch when you want a new version.
- Some features degraded — Grove, referrals, team memory sync, and anything depending on remote feature flags won't work. Core functionality (conversations, tools, file editing, bash, MCP) is unaffected.
npm install -g @anthropic-ai/claude-code
python3 patch_binary.py $(which claude) ./claude-notelemetry
After patching, run:
bash install.sh
To put it in ~/.local/bin/ so you are able to run it from the terminal
Run
sudo codesign --force --sign - --preserve-metadata=entitlements ~/.local/bin/claude-private
sudo codesign --force --sign - --preserve-metadata=entitlements ~/.local/bin/claude-notelemetry
To bypass code signing restrictions in MacOS 26. Will need to be done after every patch.
To run it (recommend LM Studio server (free) with endpoint support: anthropic-compatible
example command: ANTHROPIC_BASE_URL=http://localhost:1234 claude-private
