Privacy

Here's exactly what we receive.

Not your code, not your prompts, not your conversations. This is the whole list, straight from our FAQ.

Your work stays on your machine

We never see, store, or transmit your source code, prompts, conversations, or AI responses.

Only you see your dashboard

Org admins see aggregated totals (tokens and cost) per member, never individual sessions or event-level details.

Raw events expire after 90 days

Daily summaries are kept for trends. They contain no event details, just numbers per day.

Encrypted, and deletable

Encrypted in transit and at rest. API keys are stored as hashes. Email support@lobsterone.ai to delete everything.

New · Eco Score

Measure the climate impact of your AI-assisted coding.

Every token has an energy cost. Every marathon session heats a datacenter. Eco Score is the first sustainability metric built for developers using Claude Code, Codex, Mistral Vibe, and other frontier coding tools: a single 0–100 score with three actionable sub-scores, surfaced right in your dashboard.

Model discipline80% on frontier models

Small models for small tasks. Frontier models for the hard stuff. The right model for the job.

Cache efficiency41.3× reuse ratio

Stable context gets reused dozens of times. A measured ratio, not a guess.

Session concision13.3M median

Short focused sessions beat marathons. Attention compute is O(n²).

LobsterOne started from a simple question: how much AI is my team actually using?

After building internal dashboards that never got maintained, Pierre built LobsterOne to give every developer and engineering leader a live, accurate picture of their AI coding tool usage.

FAQ

We don't see your code. Ever.

Not your code, not your prompts, not your conversations. Anything else, just ask.

Talk to a human: support@lobsterone.ai
What data does LobsterOne collect?

Only usage metadata: token counts (input, output, cache), the model used, cost, session identifiers, tool names, and productivity counts like lines added/removed, PRs, and commits. We also collect OS type and app version for compatibility.

Do you have access to my code or conversations?

No. We never see, store, or transmit your source code, prompts, conversations, or AI responses. Only aggregated usage metrics and metadata flow through our system. The actual content of your work never leaves your machine.

How does the data collection work?

LobsterOne connects to your AI coding tools via their built-in telemetry support. The Mac app configures a telemetry endpoint. No background agents, no SDKs injected into your code, and no processes running alongside your editor.

Which AI coding tools are supported?

LobsterOne is model and tool agnostic. It works with any AI coding tool that supports OpenTelemetry, including Claude Code, Codex, and Mistral Vibe. Cursor is supported through the Claude Code plugin (claude code in terminal mode). We don't have visibility into Cursor's internal AI models, only the Claude Code usage within Cursor. Your dashboard tracks usage across all connected tools.

Who can see my data?

Only you can see your full dashboard and detailed usage history. If you're part of an organisation, your org admin can see aggregated totals (tokens and cost) per team member, but never individual sessions or event-level details.

How long is my data retained?

Raw event data is automatically deleted after 90 days. Pre-computed daily summaries (token totals, session counts) are kept for long-term trends, but these contain no granular event details, just aggregate numbers per day.

Is my data secure?

Yes. All data is encrypted in transit and at rest. API keys are stored as cryptographic hashes, never in plaintext. Our infrastructure runs in isolated private networks with no public internet exposure to the database layer.

What does the Mac app show?

The menu bar displays your real-time token consumption and quota usage as a percentage, updated every few minutes during active use. One click opens your full dashboard in the browser.

Can I delete my data?

Yes. Contact us at support@lobsterone.ai and we'll remove your account and all associated data.
