Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@stll/anonymize-cli

Command-line PII detection and anonymization powered by @stll/anonymize. Fully offline: no network calls, ever.

Usage

# No install needed
echo "Contact Jan Novák at [email protected]" | bunx @stll/anonymize-cli
# Contact [PERSON_1] at [EMAIL_ADDRESS_1]

# Or with npx / a global install (bin name: anonymize)
npx @stll/anonymize-cli contract.txt > contract.anon.txt

Reversible round-trip for LLM workflows — anonymize, send the redacted text to a model, restore names in the answer:

anonymize -k key.json -o redacted.txt input.txt
# ... send redacted.txt to the LLM, save reply as reply.txt ...
anonymize -d key.json reply.txt

Options

| Flag | Meaning | | ------------------------- | ----------------------------------------------- | | -o, --output <path> | Output file, or directory for multiple inputs | | -m, --mode <mode> | replace (reversible placeholders) or redact | | -k, --key <path> | Write the redaction key JSON (replace mode) | | -d, --deanonymise <key> | Restore text using a redaction key | | --labels <list> | Entity labels to detect (default: all) | | --languages <list> | Name-corpus languages, e.g. cs,de,en | | --countries <list> | ISO 3166-1 alpha-2 deny-list/city scope | | --threshold <n> | Minimum confidence score 0-1 (default 0.3) | | --redact-string <s> | Replacement text in redact mode | | --json | Emit entities + redacted text as JSON | | --quiet | Suppress the stderr summary |

Run anonymize --help for the full reference, including the --json schema and exit codes.

Scripting and agents

  • Exit codes: 0 success, 1 runtime error, 2 usage error.
  • The stderr summary contains entity-label counts only, never detected text.
  • The interactive locale prompt appears only when stdin and stderr are TTYs and no scope flags are given; piped runs never block.
  • --json offsets are UTF-16 code-unit indexes into the input.

Standalone binary

bun run compile produces a self-contained executable (WASM engine, dictionaries embedded as a gzip blob) that runs without Node, Bun, or npm. Cross-compile with --target=bun-linux-x64 etc.
