Apache Pulsar

  • Correspondingly harder to run well, and the expertise is rarer than Kafka expertise
  • A much smaller ecosystem of connectors, tooling and hiring pool than Kafka
  • The architectural advantages only pay off at a scale most deployments never reach

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.

Pulsar separates storage from compute and covers queuing and streaming in one system. Kafka has a far larger ecosystem and hiring pool. Most teams should have a specific reason before choosing Pulsar.

Notepad++ is licensed under the GNU General Public License v2.0 (GPLv2), meaning its source code is freely available and modifiable under GPL terms.

Apache Pulsar: Why does separated storage matter?

Brokers hold no data, so adding or replacing one requires no rebalancing, and storage can grow without adding serving capacity.

Notepad++: Which operating systems does Notepad++ support?

Notepad++ runs exclusively on Microsoft Windows; there is no official native build for macOS or Linux.

Source
Notepad++: How do I install plugins in Notepad++?

Plugins are installed and managed through the built-in Plugins Admin (plugin manager), which lists community plugins available for download and update.
