Running the load tests on Postgres (#139) found a scan reading 1.2 feeds a second: after ten minutes the first of 1,500 had reached 1,136, where SQLite does them in 27s since #135. On the databases project's server, production's, 200 single-row inserts took 2,565ms as commits of their own, 12.8ms each waiting for the WAL to reach the disk (synchronous_commit=on), 56ms with synchronous_commit=off, and 67ms in one transaction. A feed's entries and enclosures are written a row at a time, about fifty commits for 20 new items, and production's scans paid the same. ipx's own sessions now set synchronous_commit=off, through sqlx's connect options, so it holds on top of whatever options a URL sets, the tests' search_path included. A crash of the Postgres server can lose the last commits, about the last 0.6s, and never corrupts anything; a crash of ipx loses nothing; other databases on the server keep their setting. The same first scan takes 20s, and the Rust tests on Postgres 3.3s instead of 7.1s. The test of SQLite's setting checks this one too when it runs on Postgres.

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.
