How to install

Run it once without installing:

$ uvx overcast-to-sqlite

Install it permanently if you want overcast-to-sqlite available for later commands:

$ uv tool install overcast-to-sqlite

Commands

Command	Description
auth	Save authentication credentials to a JSON file
save	Fetch and save Overcast playlists, feeds, and episodes
extend	Download XML feeds and extract all tags and attributes
transcripts	Download available transcripts for episodes
chapters	Download and store available chapters for episodes
html	Generate HTML pages for played, starred, and deleted episodes
all	Run save, extend, transcripts, and chapters sequentially

Run overcast-to-sqlite --help for a full list of options.

Authentication

Run this command to login to Overcast (note: neither your password nor email are saved, only the auth cookie):

$ overcast-to-sqlite auth

This will create a file called auth.json in your current directory containing the required value. To save the file at a different path or filename, use the --auth=myauth.json option.

If you do not wish to save this information you can manually download the "All data" file from the Overcast account page and pass it into the save command as described below.

Fetching and saving updates

The save command retrieves all Overcast info and stores playlists, podcast feeds, and episodes in their respective tables with a primary key overcastId.

$ overcast-to-sqlite save

By default, this saves to overcast.db but this can be manually set.

$ overcast-to-sqlite save someother.db

By default, it will use the cookie from auth.json if present. You can point to a different location using -a:

$ overcast-to-sqlite save -a /path/to/auth.json

Alternately, you can skip authentication by passing in an OPML file you downloaded from Overcast:

$ overcast-to-sqlite save --load /path/to/overcast.opml

By default, the save command will save any OPML file it downloads adjacent to the database file in archive/overcast/. You can disable this behavior with --no-archive or -na.

For increased reporting verbosity, use the -v flag.

Extending and saving full feeds

The extend command that will download the XML files for all feeds you are subscribed to and extract tags and attributes. These are stored in separate tables feeds_extended and episodes_extended with primary keys xmlUrl and enclosureUrl respectively. (See points 4 and 5 below for more information.)

$ overcast-to-sqlite extend

Like the save command, this will attempt to archive feeds to archive/feeds/ by default. This can be disabled with --no-archive or -na.

It also supports the -v flag to print additional information.

There are a few caveats for this functionality:

1. The first time this is invoked will require downloading and parsing an XML file for each feed you are subscribed to. (Subsequent invocations only require this for new episodes loaded by save) Because this command may take a long time to run if you have many feeds, it is recommended to use the -v flag to observe progress.
2. This will increase the size of your database by approximately 2 MB per feed, so may result in a large file if you subscribe to many feeds.
3. Certain feeds may not load due to e.g. authentication, rate limiting, or other issues. These will be logged to the console and the feed will be skipped. Likewise, an episode may appear in your episodes table but not in the extended information if it is no longer available.
4. The _extended tables use URLs as their primary key. This may potentially lead to unjoinable / orphaned episodes if the enclosure URL (i.e. URL of the audio file) has changed since Overcast stored it.
5. There is no guarantee of which columns will be present in these tables aside from URL, title, and description. This command attempts to capture and normalize all XML tags contained in the feed so it is likely that many columns will be created and only a few rows will have values for uncommon tags/attributes.

Any suggestions for improving on these caveats are welcome, please open an issue!

Downloading transcripts

The transcripts command downloads available transcripts for episodes.

The save and extend commands MUST be run prior to this.

Episodes with a "podcast:transcript:url" value will be downloaded from that URL and the download's location will then be stored in "transcriptDownloadPath".

$ overcast-to-sqlite transcripts

By default this will save transcripts to archive/transcripts/<feed title>/<episode title>.

A different path can be set with the -p/--path flag.

It also supports the -v flag to print additional information.

There is also a -s flag to only download transcripts for starred episodes.

Downloading chapters

The chapters command downloads and stores available chapters for episodes. The save and extend commands MUST be run prior to this.

$ overcast-to-sqlite chapters

By default, chapters are archived to archive/ adjacent to the database file. A different path can be set with the -p/--path flag.

Generating HTML pages

The html command generates static HTML pages for recently played, starred, and deleted episodes.

$ overcast-to-sqlite html

This produces three files: overcast-played.html, overcast-starred.html, and overcast-deleted.html in the same directory as the database file.

A different output directory can be set with the -o/--output flag:

$ overcast-to-sqlite html -o /path/to/output/

The directory passed to --output is created if it does not already exist.

Running all commands

The all command runs save, extend, transcripts, and chapters sequentially in a single invocation:

$ overcast-to-sqlite all

It supports the same -a/--auth and -v/--verbose flags as save.
