## Changelog

### 2026-10-02

- Default memory now scales with the concurrency you set, so ordinary runs use less memory.

### 2026-10-01

- Runs capped by your maximum cost per run no longer stop early before the limit is actually reached.

### 2026-09-29

- Category filter options reordered by how often they are used; example domains are shown as a prefill only and are no longer used as a hidden default.

### 2026-09-27

- Runs stop cleanly at your maximum cost per run instead of being aborted; nothing beyond your limit is written or charged.

### 2026-09-24

- Analytics and ad pixels loaded through the site's public Google Tag Manager container (GA4, Meta Pixel, Google Ads and others) are now detected; new `tagManagerContainers` field.
- Microsoft Advertising (Bing UET) added; false Adobe Target matches and duplicate Vue entries fixed.

### 2026-09-23

- E-mails taken from JSON inside the page no longer come with stray characters in front, and placeholder addresses from sign-up forms are filtered out.

### 2026-09-16

- Initial release: detects what a website is built on (CMS, e-commerce, framework, analytics, ad pixels, payments, hosting, CRM, chat and more, 209 signatures across 32 categories) and adds the e-mails, phones and social profiles found on the same page, one row per site.
