The short version
- Each has a real cost: Notepad++ windows-only, with no official native macOS or Linux build.; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
- They diverge on capability: Notepad++ covers Syntax Highlighting, Sigstore covers Fulcio.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Sigstore
- The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
- It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
- Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
- Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
- Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages
Notepad++: Is Notepad++ free?
Yes, Notepad++ is free and open-source software distributed under the GNU General Public License, with no paid tiers.
SourceSigstore: Is the public instance really free?
Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.
Notepad++: What license does Notepad++ use?
Notepad++ is licensed under the GNU General Public License v2.0 (GPLv2), meaning its source code is freely available and modifiable under GPL terms.
SourceSigstore: Has the public log moved to Rekor v2?
No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.
Notepad++: Which operating systems does Notepad++ support?
Notepad++ runs exclusively on Microsoft Windows; there is no official native build for macOS or Linux.
SourceSigstore: Does Sigstore make my dependencies safe?
No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.
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.
SourceSigstore: What are the rate limits?
Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.
Notepad++: Where can I get help or documentation for Notepad++?
Official documentation is at the User Manual site, and community support is available through the Notepad++ community forum and GitHub issue tracker.
SourceSigstore: Should we self-host it?
If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
