Stalelingo – Outdated Translation Tracker for Multilingual Sites

When the source version of a post changes, its translations silently go out of date. Stalelingo fingerprints the source content every time a translation is marked as up to date. When the source changes, it flags each affected translation as outdated and shows exactly which fields changed.

Stalelingo works with Polylang (including the free version) and WPML. One of them must be active.

What it tracks

• Title, content, excerpt, and optionally the slug and featured image.
• Custom fields you choose, including ACF fields set to be translated.
• Visible Elementor text (headings, text editors, buttons). Styling-only changes are ignored.
• Formatting-only edits, such as whitespace or block attribute changes, are ignored unless you turn on strict mode.

Where you see it

• A dashboard under Tools → Stalelingo, with a matrix of posts and languages, filters, bulk actions and CSV export.
• A status column with one badge per language in your post lists.
• A panel in the block editor (and a metabox in the classic editor) with a field-by-field diff and a Mark as up to date button.
• An admin bar counter, and daily or weekly email digests for each translator.
• WP-CLI commands for reports and bulk updates.

Stalelingo is completely free. There is no paid version, no license key and no tracking, and it makes no external requests.

Privacy

Stalelingo stores the ID of the user who marked a translation as up to date, and of the user whose action changed a translation’s status. This data stays in your database. The plugin registers personal data exporters and an eraser (which removes the user from these records) and suggests text for your privacy policy. If you turn on email digests, the translators’ email addresses are used to send them.
