RegExr
RegExr is a HTML/JS based tool for creating, testing, and learning about Regular Expressions.
However - here it becomes weird - when testing the original regex rule (the first one, without the \u00A0 part) on the same string in an interactive visualiser (https://regexr.com/ for instance), there is a match:

Nutrient
Nutrient – The #1 PDF SDK Library, trusted by 10K+ developers. Other PDF SDKs promise a lot - then break. Laggy scrolling, poor mobile UX, tons of bugs, and lack of support cost you endless frustrations. Nutrient’s SDK handles billion-page workloads - so you don’t have to debug PDFs. Used by ~1 billion end users in more than 150 different countries.

qryn
qryn is a polyglot, high-performance observability framework for ClickHouse. Ingest, store and analyze logs, metrics and telemetry traces from any agent supporting Loki, Prometheus, OTLP, Tempo, Elastic, InfluxDB and many more formats and query transparently using Grafana or any other compatible client.
I'm not the person you asked -- and I also want to be transparent that I only PoC-ed it and due to external circumstances didn't get it all the way out to production -- but I really like how https://github.com/metrico/qryn (AGPLv3) thinks about the world. It is, like SigNoz, unified (logs, metrics, traces) but it actually implements several of the common endpoint schemes allowing it to pretend to be "your favorite tool" which plausibly helps any integration story <https://github.com/metrico/qryn#%EF%B8%8F-query> and <https://github.com/metrico/qryn#-vendors-compatibility>
I was going to take advantage of Clickhouse using S3 as warm-to-cold storage since my mental model is that most logs, metrics, and traces are written and not read https://clickhouse.com/docs/en/integrations/s3#configuring-s...
I believe one could do that with SigNoz, too, so I don't mean to imply that trickery was qryn specific, just that I didn't want to get into the "constantly resizing io3 PVC" game
