Data stays on your computer
Every record goes into JSON Lines files under ~/.orea/ (or $OREA_HOME), one event per line. The plugins don't connect to the internet and upload nothing.
Sumery Libra
Weigh work against recovery
Your work hours, fatigue signals and body data, side by side and computed on your own computer.
For VS Code and its forks (Cursor, Windsurf and others), and for JetBrains IDEs such as GoLand, WebStorm and IntelliJ IDEA. Tested with VS Code 1.139 and GoLand 2026.3. Free for personal use at the moment; use inside a company needs a business license.
Four steps to get started
Your IDE was open for ten hours. How much of that was spent writing code, and how much was it left untouched while you read docs or sat in meetings? At the end of the day it's hard to say, because all you can see is which window was in front.
-
Install a plugin and code as usual
When you type, delete or paste in the active editor, the plugin appends one line with the time to a file on your computer. Opening files, scrolling through code, switching windows and git rewriting files on disk write nothing.
-
Stop, and the clock stops at your last edit
Pause for a minute or two to think, then carry on: that is still one stretch. Pause for more than 3 minutes and the stretch ends at your last edit. When you switch to another app, the plugin writes out your last edit straight away.
-
Several sources, merged, nothing counted twice
The IDE plugins, DSH sessions and the macOS foreground app each keep their own record, and Libra takes the union: time seen by the editor and the terminal at once counts once. Idle time, screen lock and sleep come off the total.
-
See today and this week
Today's working time and how it compares with yesterday, your longest unbroken stretch, how many breaks you took, an hour-by-hour breakdown, and each day's time split by source.
It counts only while you are editing code
Libra's IDE plugins record time only while you are editing code. Stop for more than 3 minutes and the stretch ends at the moment of your last edit; the pause after it isn't counted.
~/.orea/ide-heartbeats.jsonl) looks like this, and that's all of it:{"source":"ide","kind":"heartbeat","at":1789500000000,"sessionId":"jetbrains:GO:/Users/me/work/libra","appId":"jetbrains:GO","appName":"GoLand","cwd":"/Users/me/work/libra"}Time, IDE name, project root. No file names, code, programming language, window titles or keystrokes.
Data and limits
Where the data lives, whether the format is yours, and what it can't do.
The format is open
The files are yours even without the Libra desktop app: tail -f ~/.orea/ide-heartbeats.jsonl shows them, and any script can add them up. The fields are explained in the plugin documentation.
Switch it off at any time
Libra has one switch per source; the plugins' switch is under 设置 → 通用 → 采集开关 (Settings → General → Collection switches). Off really stops collection rather than ignoring the data, and nothing already recorded is deleted. A plugin stops writing within seconds of being switched off, with no IDE restart.
Out of scope
- macOS Screen Time: macOS gives third-party apps no public interface to it. Libra samples the foreground app and idle time itself, and says so in the app.
- Steps, heart rate, sleep: these live on iPhone and Apple Watch; a Mac doesn't have this data. The app shows 「未连接」 (not connected) instead of filling in an estimate.
- Sogou input-method counts and Keep workouts: both rely on non-public interfaces on the other side, so an update on their end can break them. When that happens, the app shows why, not a guessed number.
- No medical judgements: Libra tells you how long you worked and how long you went without stopping. It doesn't tell you “you're tired” or “you're healthy”.
- An English interface: the desktop app is in Simplified Chinese only for now. Where this page mentions its labels, the Chinese comes first and a translation follows.
Data sources
| Source | Answers | Can't answer |
|---|---|---|
| IDE plugins | When you were editing code in a VS Code-family or JetBrains IDE | Time spent reading code or thinking a problem through (more than 3 minutes without an edit isn't counted) |
| DSH plugin | The time of every turn and every tool call in an AI coding session | What was said: it records times only, never prompts or replies |
| macOS foreground and idle | Which app is in front, how long since you touched the keyboard or mouse, screen lock and sleep | Window titles (they need an extra permission and aren't collected by default) |
| Sogou input method | How many Chinese characters you entered through the input method today | Characters typed directly on an English keyboard; what you wrote |
| Keep | Workouts, weight and resting heart rate from the Keep fitness app (not counted as working time) | All-day steps, sleep, HRV |
| Focus timer | Each focus round and break you start yourself | Work you didn't start the timer for |
Free for personal use, for now
"Free for now" is a description of today, not a long-term promise: if it ever becomes paid, what has been free does not get taken back, and released versions keep working.

Personal use · free for now
None of the capabilities listed above is paid for personal use: no paywall, no trial period, no sign-up, no online checks. Nothing is crippled, and nothing is discounted for being free.
Company use · business license
Using Libra inside a company requires a business license: ¥299 / company / year, with no seat limit. Terms, invoicing and renewal are on the business page.
The desktop app (macOS) and both IDE plugins are released; personal use follows the rules above — install and go.
Sponsor the development
Sponsoring is not a purchase and buys no feature: nothing gets better because you sponsored, and nothing gets worse because you didn't. It only says "this is useful".
