save and merge browser history and metadata from different browsers
Project description
browserexport
This:
- locates and backs up browser history by copying the underlying database files to some directory you specify
- can identify and parse the resulting database files into some common schema:
Visit:
url: the url
dt: datetime (when you went to this page)
metadata:
title: the <title> for this page
description: the <meta description> tag from this page
preview_image: 'main image' for this page, often opengraph/favicon
duration: how long you were on this page
metadata
is dependent on the data available in the browser (e.g. firefox has preview images, chrome has duration, but not vice versa)
This currently supports:
This doesn't aim to offer a way to 'restore' your history (see #16 for discussion)
This can probably extract visits from other Firefox/Chromium-based browsers, but it doesn't know how to locate them to save
them
Install
python3 -m pip install --user browserexport
Requires python3.7+
Usage
save
Usage: browserexport save [OPTIONS]
Backs up a current browser database file
Options:
-b, --browser [chrome|firefox|safari|brave|waterfox|chromium|vivaldi|palemoon|arc]
Browser name to backup history for
--form-history [firefox] Browser name to backup form (input field)
history for
--pattern TEXT Pattern for the resulting timestamped
filename, should include an str.format
replacement placeholder
-p, --profile TEXT Use to pick the correct profile to back up.
If unspecified, will assume a single profile
[default: *]
--path FILE Specify a direct path to a database to back
up
-t, --to DIRECTORY Directory to store backup to [required]
--help Show this message and exit.
Must specify one of --browser
, --form-history
or --path
Since browsers typically remove old history over time, I'd recommend backing up your history periodically, like:
$ browserexport save -b firefox --to ~/data/browser_history
$ browserexport save -b chrome --to ~/data/browser_history
$ browserexport save -b safari --to ~/data/browser_history
That copies the sqlite databases which contains your history --to
some backup directory.
If a browser you want to backup is Firefox/Chrome-like (so this would be able to parse it), but this doesn't support locating it yet, you can directly back it up with the --path
flag:
$ browserexport save --path ~/.somebrowser/profile/places.sqlite \
--to ~/data/browser_history
The --pattern
argument can be used to change the resulting filename for the browser, e.g. --pattern 'places-{}.sqlite'
or --pattern "$(uname)-{}.sqlite"
. The {}
is replaced by the browser name.
Feel free to create an issue/contribute a browser file to locate the browser if this doesn't support some browser you use.
Can pass the --debug
flag to show sqlite_backup
logs
$ browserexport --debug save -b firefox --to .

) requires a rooted Android phone.
inspect
/merge
Usage: browserexport inspect [OPTIONS] SQLITE_DB
Extracts visits from a single sqlite database
Provide a history database as the first argument
Drops you into a REPL to access the data
Options:
-s, --stream Stream JSON objects instead of printing a JSON list
-j, --json Print result to STDOUT as JSON
--help Show this message and exit.
Usage: browserexport merge [OPTIONS] SQLITE_DB...
Extracts visits from multiple sqlite databases
Provide multiple sqlite databases as positional arguments, e.g.:
browserexport merge ~/data/firefox/*.sqlite
Drops you into a REPL to access the data
Options:
-s, --stream Stream JSON objects instead of printing a JSON list
-j, --json Print result to STDOUT as JSON
--help Show this message and exit.
Logs are hidden by default. To show the debug logs set export BROWSEREXPORT_LOGS=10
(uses logging levels) or pass the --debug
flag.
As an example:

Use vis to interact with the data
[1] ...
To dump all that info to JSON:
browserexport merge --json ~/data/browser_history/*.sqlite > ./history.json
du -h history.json
67M history.json
Or, to create a quick searchable interface, using jq
and fzf
:
browserexport merge -j --stream ~/data/browsing/*.sqlite | jq '"\(.url)|\(.metadata.description)"' | awk '!seen[$0]++' | fzf
Merged files like history.json
above can also be used as inputs files themselves, this reads those by mapping the JSON onto the Visit
schema directly. If you don't care about keeping the raw databases for any other auxillary info like form or bookmark data and just want the url, visit date and metadata, you could use merge
to periodically merge the bulky .sqlite
files into a JSON dump:
cd ~/data/browsing
# backup databases
rsync -Pavh ~/data/browsing ~/.cache/browsing
# merge all sqlite databases into a single json file
browserexport --debug merge --json * > '/tmp/browsing.json'
# remove sqlite databases
rm *.sqlite *.db
# move merged data to database directory
mv /tmp/browsing.json ~/data/browsing
# test reading the merged data
browserexport merge ~/data/browsing/*
I do this every couple months with a script here, and then sync my old databases to a harddrive for more long-term storage
HPI
If you want to cache the merged results, this has a module in HPI which handles locating/caching and querying the results. See setup and module setup.
That uses cachew to automatically cache the merged results, recomputing whenever you backup new databases
As a few examples:
$ hpi doctor -S my.browser.all
✅ OK : my.browser.all
✅ - stats: {'history': {'count': 721951, 'last': datetime.datetime(2021, 4, 19, 2, 26, 8, 29825, tzinfo=datetime.timezone.utc)}}
# supports arbitrary queries, e.g. how many visits did I have in January 2020?
$ hpi query my.browser.all --order-type datetime --after '2022-01-01 00:00:00' --before '2022-01-31 23:59:59' | jq length
50432
# how many github URLs in the past month
$ hpi query my.browser.all --recent 4w -s | jq .url | grep 'github.com' -c
16357
Library Usage
To save databases:
from browserexport.save import backup_history
backup_history("firefox", "~/data/backups")
To merge/read visits from databases:
from browserexport.merge import read_and_merge
read_and_merge(["/path/to/database", "/path/to/second/database", "..."])
If this doesn't support a browser and you wish to quickly extend without maintaining a fork (or contributing back to this repo), you can pass a Browser
implementation (see browsers/all.py and browsers/common.py for more info) to browserexport.parse.read_visits
or programatically override/add your own browsers as part of the browserexport.browsers
namespace package.
You can also use sqlite_backup
to copy your current browser history into a sqlite connection in memory, without ever writing to disk:
from browserexport.browsers.all import Firefox
from browserexport.parse import read_visits
from sqlite_backup import sqlite_backup
db_in_memory = sqlite_backup(Firefox.locate_database())
visits = list(read_visits(db_in_memory))
# to merge those with other saved files
from browserexport.merge import merge_visits, read_and_merge
merged = list(merge_visits([
visits,
read_and_merge(["/path/to/another/database.sqlite", "..."]),
]))
Comparisons with Promnesia
A lot of the initial queries/ideas here were taken from promnesia and the browser_history.py
script, but creating a package here allows its to be more extendible, e.g. allowing you to override/locate additional databases.
TLDR: promnesia lets you explore your browsing history in context: where you encountered it, in chat, on Twitter, on Reddit, or just in one of the text files on your computer. This is unlike most modern browsers, where you can only see when you visited the link.
Since promnesia #375, browserexport
is used in promnesia in the browser.py
file (to read any of the supported databases here from disk), see setup and the browser source quickstart in the instructions for more
Eventually this project may be used in promnesia to replace the browser.py
file
Contributing
Clone the repository and [optionally] create a virtual environment to do your work in.
git clone https://github.com/seanbreckenridge/browserexport
cd ./browserexport
# create a virtual environment to prevent possible package dependency conflicts
python -m venv .venv
source .venv/bin/activate
Development/Testing
To install, run:
python3 -m pip install '.[testing]'
If running in a virtual environment, pip
will automatically install dependencies into your virtual environment. If running browserexport
happens to use the globally installed browserexport
instead, you can use python3 -m browserexport
to ensure its using the version in your virtual environment.
After making changes to the code, reinstall by running pip install .
, and then test with browserexport
or python3 -m browserexport
Testing
While developing, you can run tests with:
pytest
flake8 ./browserexport
mypy ./browserexport
