The old program for working with Avito that I've been using for many years has never let me down. With it, you can manage listings automatically: posting, editing, extending, and deleting them. There's also the option to upload products from an Excel file. The program has many useful features, such as solving captchas, cloning listings to different cities or districts/metro areas, which is especially relevant for Moscow and St. Petersburg, and much more. It perfectly emulates the behavior of a real person and clears cookies after each operation on Avito. If you work with multiple accounts, it allows you to spoof browser and operating system information for each one, as well as proxy binding. The interface is quite decent, although it may look outdated in some places, but for me, what's much more important is that everything functions well.
