Two ways to get TokenBeaver.

Install straight from the VS Code Marketplace, or download the .vsix and add it by hand — your call.

1. What TokenBeaver is

TokenBeaver is a VS Code extension and local gateway that sits between your AI coding agent and your model provider, trimming wasted tokens before requests are sent. Optimization happens in-process on your own device.

2. What we do not collect

We never receive, store, or transmit any of the following:

TokenBeaver optimizes in-process on your own device. Nothing from your editor or model interactions is sent to TokenBeaver's servers — requests go directly from your machine to your chosen model provider using your own key, so we are never in the path of your billing relationship with that provider.

3. What we do collect

We don't ask you to create an account, and we don't collect your email or personal profile. To handle billing and basic product analytics, we collect only a limited set of data:

4. How we use it

We use the data above to provide and secure the service, enforce free and Pro plan limits, process payments, respond to support requests, and understand aggregate product usage. We do not save or sell your data, and we do not use your code or prompts to train models.

5. Third parties

We rely on a small number of processors to run the business — for example, Stripe for payments and standard infrastructure providers for hosting our website and account systems. Your model provider (such as Anthropic) receives your requests directly from your machine under your own agreement with them.

6. Data retention & your rights

We keep billing records only as long as required for legal and accounting purposes. Since there's no account or email on file, the only data tied to you is your hashed device record. You can request deletion of your device record at any time by emailing [email protected]. Aggregate stats are anonymous and cannot be linked to a device.

7. Changes & contact

We may update this policy as the product evolves; material changes will be reflected by the date above. Questions about privacy? Email [email protected].

1. What TokenBeaver provides

TokenBeaver is a tool that optimizes AI coding requests locally on your device to reduce token usage. You bring your own model-provider API key; TokenBeaver forwards your requests to that provider unchanged except for the optimizations it applies. We don't resell model access and we aren't a party to your agreement with your model provider.

2. Accounts & plans

The Free plan includes 20 optimizations per month with full feature access. Pro is $15/month or $100/year and includes unlimited optimizations, billed through our payment processor. Pro starts with a 14-day free trial; if you don't cancel before it ends, the plan converts to paid at the price shown at signup.

3. Acceptable use

Use TokenBeaver lawfully and in line with your model provider's terms. Don't attempt to resell, reverse-engineer for circumvention, abuse the optimization service, or use it to violate others' rights. We may suspend access for activity that threatens the service or other users.

4. Your responsibilities

You're responsible for your own API keys, your model-provider charges, and the code and prompts you run through your editor. TokenBeaver runs locally and uses a fail-open design, but you should keep your own backups and review outputs before relying on them. Don't use TokenBeaver to circumvent model-provider rate limits in ways that violate those providers' terms of service.

5. Disclaimers & liability

TokenBeaver is provided as-is. We're not liable for API costs, model behavior, or data loss. Token savings are not guaranteed — results vary by session length, model, workload, and number of sub-agents. To the extent permitted by law, our liability is limited to the amount you paid us in the 6 months before a claim.

6. Changes & contact

We may update these terms as the product evolves; material changes are reflected by the date above and continued use means acceptance. Questions? Email [email protected].

1. Try before you pay

The Free plan (20 optimizations per month) and the 14-day Pro trial let you evaluate TokenBeaver at no cost. No card is charged until a trial ends, and you can cancel any time before then to avoid being billed.

2. 7-day money-back guarantee

If you're charged for Pro and aren't happy, email us within 7 days of that charge and we'll refund it in full — no interrogation. This applies to your first paid term (monthly or annual).

3. Annual plans & renewals

For annual plans, the 7-day window applies from the date of each charge, including renewals. After the window, we don't provide prorated refunds for the remainder of a term, but you can cancel to stop the next renewal and keep access until the period ends.

4. How to request one

Email [email protected] from the address on your subscription. Approved refunds are issued to your original payment method through Stripe and typically appear within 5–10 business days, depending on your bank.

Prerequisites

The TokenBeaver VS Code extension installed, and your own Anthropic API key set up for Claude Code.

1. Start the gateway

Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P) and run TokenBeaver: Start Gateway. The extension starts a local server and shows a Base URL such as http://127.0.0.1:4505/v1.

2. Point Claude Code at it

Set the base URL environment variable — note: no /v1 suffix here:

# add to your shell profile
export ANTHROPIC_BASE_URL="http://127.0.0.1:4505"

3. Verify

Use Claude Code as normal. TokenBeaver shows the optimizations applied to each request. If the gateway is ever unavailable, requests fail open and go directly to Anthropic, so your workflow never breaks.

Troubleshooting

Seeing 404s? Make sure ANTHROPIC_BASE_URL has no trailing /v1. Port already in use? Change the gateway port in TokenBeaver settings and update the variable to match.
