Leboncoin displays the current price, but not the context behind it. LBC Tools adds price history and allows you to relist your ads in a few clicks.

• See price changes at a glance: the previous price, absolute change, and percentage are displayed beside the existing price.
• Read the history of a listing: publication and renewal dates include a day count and color-coded age.
• Relist without re-entering everything: publish a replacement ad directly or open an editable draft first.

LBC Tools only runs on leboncoin.fr and uses Leboncoin’s own authenticated session to perform the actions you explicitly request. It does not send your data to a third-party service.

Relisting uses Leboncoin’s web APIs, which can change without notice. Always review an editable draft before publishing and make sure the selected price is correct.

Ideas, bug reports, and pull requests are welcome. Please open an issue first for significant changes so the implementation can be discussed.
