The browser tests drive one person against a handful of feeds, one request at a time, and cannot
show what production's load does. node tests/load/run.js builds a release binary, serves 1,500
generated feeds from itself, starts a daemon of its own under /tmp/ipx-load, seeds a hundred
listeners with thirty feeds each and four downloaded files, and runs four k6 scripts, with
`ipx status` -- the healthcheck -- run every second and failing the run at its 5s timeout:
browse 25 people at once: feed list, All Subscriptions, a feed, a search, the Directory,
a feed's page in it
listening 100 players saving positions every second and marking items read while scans write;
each reads its own state back, which must be as it left it
media 50 listeners seeking: every range checked byte for byte against the served file
signin a flood of wrong passwords while others browse, and the gap between refusing a
known name and an unknown one
Each budget is about twice what it measures now. Getting here found #135 (SQLite waiting for the
disk after every write, a first scan of 1,500 feeds estimated at 50 minutes, now 27s), #136
(SQLite's single connection, left open), #137 and #138 (fixed in the commit before this). k6 is
installed from its own signed apt repository by /src/install.sh, outside this repository.

ipx
A self-hosted podcatcher for a household. It checks your feeds, downloads the episodes, and serves
a web UI modelled on the 2004 Mac app iPodderX, for any number of people sharing one copy of
the files. One Rust binary, ipx, is both the daemon and the command line.
It is a rewrite of ipodderx-core, the Python engine behind iPodderX (2004-2008, Ray Slakinski & August Trometer).
What it does
- The web UI. It has a toolbar, and a feed list that opens with the Directory, Currently Listening and All Subscriptions. Items sit in a sortable table with a Files pane, and there is a player bar. It comes in Dark, Light and Classic themes, and works on a phone.
- Several people, one copy. Each person has their own subscriptions and their own read, pinned and playback state. There is one file on disk per episode, however many people want it. People sign in with a password or through a proxy (Cloudflare Zero Trust or Authentik), and admins manage accounts and settings.
- Scanning. Feeds are checked on a schedule, globally or per feed, and a feed's own TTL is honoured. Keyword, explicit-content and media-type filters decide what is downloaded, with a limit on how many of a feed's newest episodes are downloaded.
- Downloads. Files come over HTTP or BitTorrent and are filed into a folder per feed. Retention deletes the oldest files to stay under a disk quota or an age limit, and never touches an item someone has pinned.
- OPML. You can import and export your own subscriptions. You can also subscribe to an OPML URL, which keeps a whole list in step as a folder.
Run it
With Docker:
docker build -t ipx .
docker compose up -d
docker-compose.yml is set up for the author's own server. Point its image and its three volumes
(/config, /data and /downloads) at yours first. The UI is on port 8099. BitTorrent uses 6881
over TCP and UDP. Files are written as PUID/PGID, 99:100 by default.
From source:
cargo build --release
./target/release/ipx daemon
The first start creates admin / ipodderx. Sign in at /login, then change it:
echo -n 'a good password' | ipx user passwd admin
The UI is plain HTTP, so put TLS in front of it if it is reachable from outside your network.

Tests
cargo test # the engine: parsing, filters, retention, schedules, SQL, per-user state
node tests/page-smoke.js # the page script loads without throwing
node tests/native-bridge.js # the page hands playback to a native shell
npx playwright test # a real browser against a real daemon on fixture feeds
npm install gets the test runner, and npx playwright install --with-deps chromium gets the
browser.
