Features

Everything about your spend at a glance

The extension repeats only the requests the DeepSeek web console makes and turns them into a readable dashboard.

Wallet balance

Paid and bonus balance shown separately. The badge turns red once your balance drops below the threshold you set.

Spend today

Today's spend and token count. “Today” is fetched on its own so the number is accurate until the day rolls over.

Per-key accounting

See which key costs the most. The badge and the chart can be scoped to a single key or any selection of keys.

30-day chart

Daily bars for the selected window. Click keys in the list and the bars become stacked segments with a colour legend.

Badge on your metric

Spend today, spend in the period, balance or tokens — you decide what the toolbar icon shows.

Auto refresh

Data refreshes in the background on a schedule (once a minute by default) or not at all. A manual refresh button is always there.

Budgets

Stop overpaying
for API keys

Set a daily budget for the whole account and one for each key. The badge turns green, orange or red according to the budget closest to its limit.

  • Account-wide budget plus independent per-key budgets
  • Configurable warning threshold (90 % by default)
  • Desktop notification when nearing and when exceeding a limit
  • One notification per day per budget — no spam

How it works

Three steps to your first chart

No separate sign-up and no API key — the extension reuses the session already open in your browser.

01

Install the extension

One click from the Chrome Web Store. Requires Chrome 116 or newer.

02

Open platform.deepseek.com

Sign in — the session is picked up automatically.

03

Click the toolbar icon

The first refresh happens by itself. After that data updates in the background.

Screenshots

What it looks like

Dark interface, dense grid and not a single unnecessary button.

Popup: balance, spend today and chart

Popup

Balance, today's spend and tokens, budget bars, chart and the list of API keys.

Options page: badge, refresh, budgets, session

Settings

Badge metric, key selection, refresh interval, aggregation window, budgets and thresholds.

Private by default

The extension talks only to platform.deepseek.com and makes the same read-only requests the DeepSeek web console does. No API key and no password are stored — it reuses the session already open in your browser. All data stays on your own computer: no telemetry, analytics, ads or third-party sharing. Remove the extension and the data is gone.

3 requests

Only the console endpoints needed for balance and spend.

0 third-party domains

No external servers, CDNs or error reporting.

Local storage

Settings and cached figures live in chrome.storage.local.

Open source

MIT licence, sources on GitHub — every line can be checked.

FAQ

Frequently asked

Do I need a DeepSeek API key?

No. The extension uses the session already open in your browser on platform.deepseek.com. No API key or password is requested or stored.

Does the extension send my data anywhere else?

No. Requests go only to platform.deepseek.com; everything else stays local. No analytics, telemetry or ads.

The badge shows “−”, what should I do?

The DeepSeek WAF token expired. Open platform.deepseek.com once — the token renews itself and the extension picks it up on the next refresh. The extension never opens tabs on its own.

The badge shows “!” or an authorization error

The session was not found or has expired. Sign in to the platform, then press “Re-detect session” in the extension settings.

How accurate is the “today” figure?

The platform's daily series does not include the current day until it ends, so the extension takes “today” from the hourly series and adds it to the chart separately.

Is there a Firefox version?

Chrome and Chromium-based browsers only (Edge, Brave, Arc) — Chrome 116+ is required.

Install for free

The extension is completely free and open source.
