Plugins

WooCommerce plugins by Nestero

We build the extensions we needed ourselves while running client stores. Each one finishes a single job instead of adding a settings screen with thirty switches.

Principles

What our plugins have in common

GPL licence, no locked code

Read it, change it, keep it running after we part ways. Nothing is obfuscated and nothing stops working when a licence expires.

Your data stays yours

The plugin talks to your store and to the service you point it at. Order contents and customer records never reach Nestero.

Support from the authors

Your report lands with the person who wrote the code. We answer within one working day, in English or Polish.

Maintenance

What happens after you install it

Updates that follow WooCommerce

Every release is checked against the current and previous WooCommerce version and two PHP versions. Breaking changes are written down in the release note before they ship.

Bugs go to a person

Tell us what happened and on which version. Security fixes jump the queue; everything else lands in the next release.

Free stays free

What costs nothing today does not move behind a paywall later. Pro adds features instead of taking existing ones away.

Need something of your own

We write single-store extensions to order. The code and the rights to it become yours.

Questions

Common questions about our plugins

Are the plugins free?

The free version is genuinely free: no document limit, no expiry date and no account with us. Pro versions are sold separately in our shop and add features the free build never had.

What licence do you release them under?

GPL v2 or later, the same as WordPress itself. You can read the code, change it and keep it on your store even if we stop developing it. Nothing is obfuscated and nothing switches off when a licence lapses.

Does the plugin send my data to Nestero?

No. The extension talks to your store and to the service you point it at in the settings. Order contents and customer records never leave that path, and the API keys stay on your side.

What if the plugin breaks after a WooCommerce update?

Tell us which WooCommerce and PHP version you are on. Security fixes and bugs that stop sales jump the queue; everything else lands in the next release. Your report is read by the person who wrote the code.

Will you build a plugin for my store?

Yes, that is a normal development job. Describe what is missing and you get a proposed scope and price range back. The code and its copyright transfer to you once the invoice is paid.

Need a plugin that is not here yet?

Describe what your store is missing. You get a proposed scope and a price range back, with nothing to sign.
