Youpdated

A dynamic scraper that collects update information about the games, apps, and packages you follow, and reports back what changed.

It is built to be privacy-preserving, anonymous, and customizable: no accounts, no API keys required, nothing stored anywhere non-local.

1. Install

Requires Python 3.11 or newer (python3 --version to check). CI runs the full suite on Linux, macOS, and Windows across Python 3.11–3.14.

cd /path/to/Youpdated
python3 -m venv .venv
.venv/bin/pip install .

On Windows, use python and the Scripts directory:

python -m venv .venv
.venv\Scripts\pip install .

That installs a youpdated command inside the virtualenv, at .venv/bin/youpdated on macOS/Linux and .venv\Scripts\youpdated.exe on Windows. Either call it by that full path, or put it on your PATH:

export PATH="$PWD/.venv/bin:$PATH"           # macOS / Linux
youpdated --version                          # -> youpdated 0.1.0

$env:PATH = "$PWD\.venv\Scripts;$env:PATH"   # Windows
youpdated --version

To make that permanent, add the export line to your ~/.zshrc, or the $env:PATH line to your PowerShell profile. Examples assume youpdated is on your PATH; if it isn't, substitute the full path above.

2. Create your config

youpdated init

This writes a commented starter config and prints the path it used, which is:

OS	Config file	History database
macOS	~/Library/Application Support/youpdated/config.yaml	~/Library/Application Support/youpdated/state.sqlite3
Linux	~/.config/youpdated/config.yaml	~/.local/share/youpdated/state.sqlite3
Windows	%LOCALAPPDATA%\youpdated\config.yaml	%LOCALAPPDATA%\youpdated\state.sqlite3

Three locations are checked, (in this order) the first one found chosen:

1. --config PATH, if you pass it
2. ./youpdated.yaml or ./youpdated.yml in the current directory
3. the per-user path in the table above

Use youpdated init -c ./youpdated.yaml if you'd rather keep the config in a project folder. Add --force to overwrite an existing file.

3. Edit it to watch what want

Open the file printed. Every source entry takes a bare value or a mapping. A minimal config:

sources:
  github:
    - python/cpython
  npm:
    - express

Where to find identifiers

You want to watch	Put this in the config	How to find it
A GitHub repo	python/cpython	The owner/repo part of the repo URL. A full https://github.com/owner/repo URL also works.
An npm package	express, "@types/node"	The package name on npmjs.com. Quote scoped names: YAML treats a leading @ specially.
A Steam game	440	The number in the store URL: store.steampowered.com/app/440/Team_Fortress_2/. The full store URL also works, and the game's name is looked up for you.
An itch.io game	https://user.itch.io/game-name	The game's page URL, exactly as it appears in the address bar.
A YouTube channel	"@NASA"	The @handle from the channel URL. A UC… channel id or full channel URL also works. Quote it: YAML treats a leading @ specially.
A YouTube playlist	playlist: PLxxxx	The list= parameter in the playlist URL. A full playlist URL also works.
A browser	chrome, brave, firefox, edge	Just the name. Add platform: and channel: to narrow it. See the full example.
Anything else	https://example.com/feed.xml	Any RSS or Atom feed URL. Many apps publish one at /feed.xml, /releases.atom, or /blog/rss.

      limit: 5

Check your config without sending a request:

youpdated check --test -v

That validates the file and prints every URL it would fetch. Config mistakes exit 1 with a message naming the offense.

4. Run

youpdated check

The first run reports nothing It records a baseline of what exists, so that later runs show changes rather than every item published:

╭──────────── first run ─────────────╮
│ Baseline recorded for 15 target(s),│
│ 142 existing item(s).              │
│ Future runs report only what's new.│
╰────────────────────────────────────╯

To see the current state right away, add --all:

youpdated check --all

From then on, youpdated check prints only what changed since the previous run.

---

Command reference

youpdated check                       # what's new since last run (the default command)
youpdated check --all                 # everything currently published, ignoring history
youpdated check --since 7d            # only items from the last week (30m, 12h, 7d, 2w)
youpdated check -s github -s npm      # limit to some sources
youpdated check --json                # machine-readable output
youpdated check --rss ~/feeds/you.xml # aggregated Atom feed for a reader
youpdated check --test -v             # test to show what it would request
youpdated check --no-save             # report without recording anything as seen
youpdated check --fail-on-error       # exit 2 if any source failed
youpdated check -v                    # show each request, its status, and item summaries
youpdated check --state ./test.db     # use a throwaway history file
youpdated sources                     # list available sources
youpdated init --force                # rewrite the starter config
youpdated uninstall --test            # list every file the tool wrote

Running youpdated with no arguments runs youpdated check.

--json writes only JSON to stdout; progress and errors go to stderr, so this is safe:

youpdated check --json | jq '.updates[] | select(.source == "github") | .title'

Exit codes: 0 success, 1 config error, 2 with --fail-on-error when a source failed, 130 on interrupt.

Running it on schedule

Once a day is plenty, most of these sources change slowly, and conditional requests make repeat runs cheap. Use absolute paths, since cron and launchd don't inherit your shell's PATH.

cron (crontab -e) run at 9am and append to a log:

0 9 * * * /path/to/Youpdated/.venv/bin/youpdated check >> ~/youpdated.log 2>&1

Keep an RSS feed fresh for a reader to poll. Note that --rss writes that run's items, so a plain check --rss leaves almost an empty file. For a feed that always holds a rolling window, ask for it. --no-save keeps this from interfering with your daily incremental run:

0 * * * * /path/to/Youpdated/.venv/bin/youpdated check --all --since 30d --no-save --rss ~/feeds/youpdated.xml

macOS launchd: save as ~/Library/LaunchAgents/com.youpdated.check.plist, then launchctl load ~/Library/LaunchAgents/com.youpdated.check.plist:

<?xml version="1.0" encoding="UTF-8"?>
<plist version="1.0"><dict>
  <key>Label</key><string>com.youpdated.check</string>
  <key>ProgramArguments</key>
  <array>
    <string>/path/to/Youpdated/.venv/bin/youpdated</string>
    <string>check</string>
    <string>--rss</string>
    <string>/Users/you/feeds/youpdated.xml</string>
  </array>
  <key>StartCalendarInterval</key><dict><key>Hour</key><integer>9</integer></dict>
  <key>StandardOutPath</key><string>/tmp/youpdated.log</string>
  <key>StandardErrorPath</key><string>/tmp/youpdated.err</string>
</dict></plist>

Troubleshooting

Symptom	Cause and fix
Config error: no config file found	Run youpdated init, or pass --config PATH.
First run printed nothing	Working as intended — it recorded a baseline. Run youpdated check --all to see current items.
--all shows fewer items than expected	Nothing is wrong; sources cap how much history they expose (10–20 items each).
A source appears in the yellow problems panel	That one source failed; the rest of the run still completed. Re-run with -v to see the request and status.
unknown source 'X'	Check spelling against youpdated sources.
YouTube fails every path	Its feed throttles intermittently. Retry, or set privacy.proxy, or export YOUTUBE_API_KEY.
An itch game reports nothing	It has neither a devlog nor a file listing. Confirm with youpdated check -s itch --all -v.
Everything reports as new again	The history database was deleted or --state points somewhere new.
youpdated: command not found	The virtualenv isn't on your PATH. Use .venv/bin/youpdated.
ModuleNotFoundError: youpdated	You used pip install -e . on MacOS

To start over from a clean slate, delete the history database (the path is in the table in step 2); your config is untouched.

Uninstalling

Youpdated writes two files, but it will find and remove them for you. Always check first:

youpdated uninstall --test

That prints every path it would delete. When you're ready:

youpdated uninstall

It lists the files again and waits for you to confirm. Add --yes to skip the prompt in a script. It refuses rather than assuming consent.

youpdated uninstall --keep-config     # wipe history, keep your config
youpdated uninstall --state ./test.db # also remove a database from --state

Two rules: a directory is removed only if it is named youpdated and is empty once the tool's own files are gone. Anything else is kept and reported.

It prints the command to remove the package itself. (which it can't do while running):

/path/to/.venv/bin/python -m pip uninstall youpdated

If you installed into a dedicated virtualenv, deleting that directory removes the package too.

Privacy

• No credentials. Every source works unauthenticated. GITHUB_TOKEN and YOUTUBE_API_KEY are read from the environment if set (only for raising rate limits) and are never written to config.

• Local only. Config and history live in your platform's config/data directories. Nothing is sent anywhere except the sources you list.

• One HTTP path. Every request goes through youpdated/http.py. privacy.proxy covers all traffic. To check:

  youpdated check --all --no-save    # with privacy.proxy: socks5://127.0.0.1:9

• Cookies are discarded on every request, so nothing accumulates across a run.

• Requests are paced per host with random jitter instead of arriving in a burst.

• Conditional GETs (ETag / Last-Modified) mean unchanged feeds are re-fetched cheaply, which is both faster and less fingerprintable. --all turns them off, since a 304 has no items.

Development

Install the test dependencies and run the suite from the repo root:

.venv/bin/pip install ".[dev]"
PYTHONPATH=$PWD .venv/bin/python -m pytest

PYTHONPATH=$PWD is what makes your working-tree changes take effect without reinstalling. Run the CLI the same way while developing:

PYTHONPATH=$PWD .venv/bin/python -m youpdated check --test -v

Tests run entirely offline: each parser is exercised against real captured payloads in tests/fixtures/ via respx, which fails the test rather than allowing a real request. After changing source code, reinstall with .venv/bin/pip install . to update the youpdated command itself.

Contributing

main is protected by a branch ruleset, changes arrive by pull request:

git switch -c my-change
# ...work, commit...
git push -u origin my-change
gh pr create --fill

The ruleset requires a pull request (no approvals needed), all 13 test jobs green, and the branch up to date with main; force-pushes and branch deletion are blocked. See ADDING_SOURCES.md if your change is a new source.

Building a release

.venv/bin/pip install ".[publish]"
rm -rf dist build *.egg-info
.venv/bin/python -m build          # -> dist/*.whl and dist/*.tar.gz
.venv/bin/twine check dist/*       # metadata and README render check

Verify the artifact before uploading, by installing the wheel into a throwaway virtualenv rather than trusting the source tree:

python3 -m venv /tmp/verify
/tmp/verify/bin/pip install dist/youpdated-*.whl
/tmp/verify/bin/youpdated sources

Then publish. Uploading needs a PyPI account and an API token. Create one under Account settings --> API tokens, scoped to this project once it exists (for a first upload the token has to be account-wide):

.venv/bin/twine upload dist/*
# username: __token__
# password: pypi-...   (the token, including the pypi- prefix)

Test against TestPyPI first if you want to see the rendered project page before it's permanent:

.venv/bin/twine upload --repository testpypi dist/*

Then tag it and cut a GitHub release:

git tag -a v0.1.0 -m "v0.1.0"
git push origin v0.1.0
gh release create v0.1.0 dist/* --notes-from-tag

A version is permanent. PyPI refuses to replace an existing version even after a delete, so bump version in pyproject.toml before rebuilding. Add the matching CHANGELOG.md entry in the same commit.

Adding a source

See ADDING_SOURCES.md for the full guide.

The short version: implement targets() and fetch() from the protocol in youpdated/sources/base.py, decorate the class with @register, and import it in youpdated/sources/__init__.py. Reuse entry_fields() so your source accepts both the bare-value and mapping config shapes, and parse_feed() from youpdated/sources/feed.py if the upstream is RSS/Atom. Third-party packages can register a source through a youpdated.sources entry point instead, without modifying this repo.
