* ci(performance): give the initial-bytes ratchet slack and a labelled override The exact renderer.initialBytes counter failed PRs for reasons outside their diff: two concurrent merges left master 108 bytes over the baseline for hours, and bundler identifier renaming moves the counter by hundreds of bytes. PRs growing it by 243 and 302 bytes had no way to pass at all, because the direction check refuses any raised baseline. - Counter entries accept `slack` (integer, entry unit): the ratchet enforces `value + slack`, reports how much slack a measurement uses, and still prints the tighten hint below `value`. renderer.initialBytes gets 4096 bytes, so growth can accumulate at most 4 KiB past the last lowered baseline while regressions such as +35 KB still fail. - check-baseline-direction.mjs compares `value + slack`, treats widened slack like a widened tolerance, and takes `--allow-increase`, which reports weakened entries as ALLOWED instead of failing. - CI passes `--allow-increase` only when the pull request (or, for a master push, the pull request merged as the pushed commit) carries the perf-baseline-increase label, read from the API so a job re-run picks up a label added later. This change widens the slack itself, so its own PR needs the label.

Only entries with `slack` report it now. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0166PWobUjpoiWt8E9bBdsCs * fix(performance): scope the push-time label and refuse raised counter values - A master push compares the whole push, but the label was read from the head commit's PR only, so one labelled PR could cover another commit's increase in the same push. The label now counts only when the push added exactly one first-parent commit (a squash or merge of one PR); any other push that weakens a baseline fails. - Raising a counter's `value` while narrowing its `slack` lowered the enforced limit and was reported as "lowered". A counter's value is the measured evidence and only moves down, so that raise is now a weakening that needs the label. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0166PWobUjpoiWt8E9bBdsCs * fix(performance): treat a counter/wall-clock type switch as a weakening Turning `{ value: 100, slack: 10 }` into `{ value: 105, toleranceRatio: 1 }` skipped the raised-counter-value rule and was reported as a lowered limit. Switching an entry between counter and wall-clock now needs the perf-baseline-increase label. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0166PWobUjpoiWt8E9bBdsCs * ci(performance): paginate the label lookups of the direction check The labels endpoint returns 30 entries per page by default, so a PR with more labels could miss perf-baseline-increase. Both lookups now request 100 per page and paginate, like the release-note gate.

IPTVnator - IPTV Player Application
🌐 Website | Telegram channel for discussions | Buy me a coffee | GitHub Sponsors
IPTVnator is a video player application that provides support for IPTV playlist playback (m3u, m3u8). The application allows users to import playlists using remote URLs or by uploading files from the local file system. Additionally, it supports EPG information in XMLTV format which can be provided via URL.
The application is a cross-platform, open-source project built with Electron and Angular.
⚠️ Note: IPTVnator does not provide any playlists or other digital content. The channels and pictures in the screenshots are for demonstration purposes only.
Important
Official sources only. IPTVnator is a free, open-source player — it never sells IPTV subscriptions, channels, or playlists. Websites offering "IPTVnator subscriptions/channels/premium/activated" builds are not affiliated with this project. Get the app only from the official website or GitHub Releases. See Beware of unofficial IPTVnator websites and IPTV services for details.

Note: First version of the application which was developed as a PWA is available in an extra git branch.
Self-hosted PWA
The Docker setup builds the Angular PWA and the monorepo web backend into one
image. The backend handles remote M3U parsing plus Xtream and Stalker proxy
requests under /api, so a separate 4gray/iptvnator-backend container is not
required for the default self-hosted flow.
docker compose -f docker/docker-compose.yml up --build -d
The application is available at http://localhost:4333. See
docker/docker-compose.yml for the ready-to-run
compose file and docker/README.md for environment
variables, reverse proxy notes, PWA limitations, and build details.
The self-hosted image runs the browser PWA rather than the Electron desktop app: EPG/XMLTV panels, Embedded MPV, managed MPV/VLC launching, the download manager, and Electron remote-control features are not available there. If browser playback fails, copy the stream URL and open it manually in an external player such as MPV, VLC, or IINA.
Download
Download the latest version of the application for macOS, Windows, and Linux from the release page.
Alternatively, you can install the application using one of the following package managers:
Nightly builds
Every merge into master is published as a prerelease in
4gray/iptvnator-nightly. The
desktop app can follow them: Settings → About → Update channel → Nightly
offers each new build through the built-in updater (macOS, Windows, and the
Linux AppImage). Nightly builds are untested snapshots — they may break, and
their database changes are permanent, so switching back to Stable keeps
the installed nightly until the next stable release is newer. Back up your
playlists first, and mention the version and commit shown in About when
reporting a bug from a nightly.
Homebrew
$ brew install iptvnator
Snap
$ sudo snap install iptvnator
Arch
Also available as an Arch PKG, iptvnator-bin, in the AUR (using your favourite AUR-helper, .e.g. yay)
$ yay -S iptvnator-bin
Gentoo
You can install IPTVnator from the gentoo-zh overlay
sudo eselect repository enable gentoo-zh
sudo emerge --sync gentoo-zh
sudo emerge iptvnator-bin
Linux Embedded MPV Support
Embedded MPV on Linux is experimental and currently supports x64 desktop
sessions where IPTVnator runs under X11 or Xwayland. Native Wayland embedding
is not supported yet. Linux package launchers request X11 with
--ozone-platform=x11, so Wayland desktops still need Xwayland available.
The Linux backend starts a system mpv executable with --wid, so mpv must
be installed and available on PATH. CI validates the Linux native addon and
standard packages on Ubuntu 22.04, with Flatpak packaging built on Ubuntu 24.04.
Expected user targets are Ubuntu/Debian .deb, Arch/Manjaro pacman, RPM
distributions, and AppImage on x64 systems with X11/Xwayland plus mpv
installed. Flatpak and Snap builds remain available, but embedded MPV is not
announced as supported there yet because those sandboxed formats do not expose
the host mpv executable to the embedded backend by default.
Troubleshooting
macOS: "App is damaged and can't be opened"
Older unsigned macOS builds may require removing the quarantine flag from the downloaded application:
xattr -c /Applications/IPTVnator.app
Alternatively, if the app is located in a different directory:
xattr -c ~/Downloads/IPTVnator.app
Linux: chrome-sandbox Issues
If you encounter the following error when launching IPTVnator:
The SUID sandbox helper binary was found, but is not configured correctly.
Rather than run without sandboxing I'm aborting now.
You need to make sure that chrome-sandbox is owned by root and has mode 4755.
Solution 1: Fix chrome-sandbox permissions (Recommended for .deb/.rpm installations)
Navigate to the IPTVnator installation directory and run:
sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox
Solution 2: Launch with --no-sandbox flag
Edit the desktop launcher file to add the --no-sandbox flag:
-
Find your desktop file location:
- Ubuntu/Debian:
~/.local/share/applications/iptvnator.desktop - System-wide:
/usr/share/applications/iptvnator.desktop
- Ubuntu/Debian:
-
Edit the file and modify the
Execline:Exec=iptvnator --no-sandbox %U -
Save the file and relaunch the application from your application menu.
Alternatively, you can launch IPTVnator from the terminal with the flag:
iptvnator --no-sandbox
GNU/Linux: Wayland startup failure
If IPTVnator exits on GNU/Linux with errors about failing to connect to Wayland or initialize the Ozone platform, force X11/XWayland instead:
iptvnator --ozone-platform=x11
This workaround is mainly for older or problematic Linux graphics stacks. The Snap package already includes this X11 override by default. For AppImage, direct binaries, and other Linux package formats, pass the flag manually when needed.
How to Build and Develop
Requirements:
- Node.js 22.22.3 or newer within 22.x, or 24.15.0 or newer within 24.x
- pnpm 10.33.0 (via Corepack)
The repository's .nvmrc pins the Node.js version used by CI. With nvm,
run nvm install and nvm use from the repository root to use the same version
for local development.
-
Clone this repository and install project dependencies:
$ nvm install $ nvm use $ corepack enable $ pnpm install -
Start the application:
$ pnpm run serve:backend
This will open the Electron app in a separate window, while the Angular dev server will run at http://localhost:4200.
The equivalent Nx command is:
$ nx serve electron-backend
To start Electron with an empty, isolated data directory instead of your normal
~/.iptvnator folder, set IPTVNATOR_E2E_DATA_DIR for that run:
$ rm -rf .tmp/iptvnator-empty && mkdir -p .tmp/iptvnator-empty
$ IPTVNATOR_E2E_DATA_DIR="$PWD/.tmp/iptvnator-empty" pnpm run serve:backend
This redirects the SQLite database, Electron user data, and local config under the given directory. Delete that directory whenever you want a fresh empty state.
If you need startup diagnostics for a white screen or a frozen route, you can also turn on opt-in Electron tracing. These logs are written to the Electron terminal output so they still help when the renderer DevTools never open:
$ IPTVNATOR_TRACE_STARTUP=1 pnpm run serve:backend
Nx equivalent:
$ IPTVNATOR_TRACE_STARTUP=1 nx serve electron-backend
Useful narrower flags:
IPTVNATOR_TRACE_IPC=1logs rendererwindow.electron.*calls reaching the Electron bridgeIPTVNATOR_TRACE_DB=1logs DB worker requests and request-scoped DB eventsIPTVNATOR_TRACE_SQL=1logs SQLite statements in both the main connection and DB worker connectionIPTVNATOR_TRACE_WINDOW=1logs BrowserWindow load, navigation, and unresponsive eventsIPTVNATOR_TRACE_RENDERER_CONSOLE=1mirrors renderer console messages into the Electron terminal output
Security-sensitive network compatibility flags are opt-in:
IPTVNATOR_ALLOW_PRIVATE_NETWORK_URLS=1permits strict EPG fetches from playlist metadata (x-tvg-url,url-tvg, ortvg-url) to resolve to localhost, LAN, or other private addresses. Directly configured Xtream/Stalker portals and private playlist servers remain supported without this flag. Prefer the in-app source-scoped “Allow source” action for a trusted EPG URL.IPTVNATOR_ALLOW_INSECURE_TLS=1disables certificate validation for remote playlist imports and refreshes for the whole Electron process. Prefer the in-app host-scoped trust action for a trusted provider with a self-signed or otherwise invalid certificate.
If the local Nx daemon gets into a bad state before rerunning Electron, reset it:
$ pnpm nx reset
To run only the Angular app without Electron, use:
$ pnpm run serve:frontend
To see how many bytes the built web app puts on the initial load path (the number the CI ratchet guards), build it and run the measurement:
$ pnpm nx build web
$ pnpm run perf:initial-bytes
The contract behind that number is in docs/architecture/performance-journeys.md.
To benchmark the "launch to usable" journey (fresh Electron process on a seeded profile, exact renderer counters plus wall-clock), run:
$ pnpm run perf:journeys
The journeys, their counters and the summary written under
dist/performance/journeys/ are described in
docs/architecture/performance-journeys.md.
