syndicationd maintains state (such as subscribed feeds) on the backend, and therefore requires authentication to make requests.
Currently, GitHub and Google are supported as authorize server/id provider. The only scope syndicationd requires is user:email(Github) or email(Google) to read the user's email. the user's email is used only as an identifier after being hashed and never stored.

Subscribe feed

To subscribe a feed, type "Tab" to move to Feeds tab and then press "a".
synd uses edit to launch the user's editor(like a git commit).
The feed to subscribe to should be entered in the format:
Requirement Category URL

When you close the editor, the subscription request is sent to the API.


Requirement indicates the importance of the feed.
This uses an analogy to RFC2119 and can take one of the following values:

  • MUST: Most important, must be read.
  • SHOULD: Next in importance, should be read unless there is a special reason not to.
  • MAY: Lowest importance, may be read.


Category represents the category of the feed. You can specify any value as a category. The values that synd recognizes as categories are defined in categories.toml. You can override the default values with the --categories flag.

Edit subscribed feed

To change the requirement or category of a feed you have already subscribed to, select the target feed in the Feeds tab and then press "e".

Unsubscribe feed

To unsubscribe from a feed, select the target feed and press "d".

Filter feeds/entries

Feeds and entries can be filtered as follows.

By requirement

To filter bases on the specified requirement, press "h/l(Left/Right)".
If you set the filter to MUST, only those marked as MUST will be displayed. Setting it to SHOULD will display feeds and entries marked as MUST and SHOULD. If set to MAY, all feeds and entries will be displayed.

By categories

To filter bases on categories, presess "c". This will display a label with keys to control the activation/deactivation of each category, allowing you to toggle the visibility of categories.
Pressing "-" will deactivate all categories, and pressing "+" will activate all categories.

You can exit the filter category mode by pressing the "Esc" key.
The icons for categories can be specified in categories.toml

Export subscribed feeds

To export subscribed feeds, execute the synd export command.
You can check the JSON schema of the data to be exported with synd export --print-schema

Click to show a export json schema
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Export",
  "type": "object",
  "required": [
  "properties": {
    "feeds": {
      "type": "array",
      "items": {
        "$ref": "#/definitions/ExportedFeed"

        "title": {
          "type": [
        "url": {
          "type": "string"

Log file

The log file path is based on ProjectDirs::data_dir().
Please refer to the --log flag in synd --help for the default output destination.

You can modify the log directives using the environment variable SYND_LOG. (for example, SYND_LOG=synd=debug)


The theme can be changed using the --theme flag. Please refer to the help for the values that can be specified.

Backend api

By default, synd use https://api.syndicationd.ymgyt.io as the backend api(hosted on my home Raspberry Pi).
To change the endpoint, specify the --endpoint flag

The hosted api is instrumented with OpenTelemetry. Basic signals(traces,metrics,logs) are published on the Grafana

Remove cache and logs

Authentication credentials are cached. to remove them, execute synd clean.

Check application status

synd check [--format (human|json)] return current application status.

Feed tips

Some tips about feed that I know.

  • Add openrss.org/ to the beginning of the URL to get its RSS feed. for example, for https://example.ymgyt.io, it would be https://openrss.org/example.ymgyt.io

  • You can retrieve various updates as feeds on GitHub.

    • To obtain releases of a repository, specify releases.atom. for example, to obtain releases of syndicationd, specify https://github.com/ymgyt/syndicationd/releases.atom
    • For tags, it's https://github.com/ymgyt/syndicationd/tag.atom
  • Adding .rss to the end of a Reddit URL allows you to retrieve the feed. for example, for https://www.reddit.com/r/HelixEditor/, it would be https://www.reddit.com/r/HelixEditor.rss

If you're looking for feeds, here are my recommendations.
