Is casperjs still maintained?

No — casperjs stopped being maintained around March 2018. The ecosystem moved to playwright, a separate project that took over the same job.

What should I use instead of casperjs?

The ecosystem moved to playwright, a separate project that took over the same job. playwright is not a drop-in replacement, so expect to change call sites.

How to migrate from casperjs to playwright

CasperJS step chains map onto plain async/await scripts; casper.start().then(...) becomes await page.goto(...) followed by ordinary awaited actions.

Why casperjs is on this list

CasperJS is a scripting layer on top of PhantomJS, and PhantomJS development was suspended in March 2018. The CasperJS repository is archived and its own description begins "CasperJS is no longer actively maintained"; the last release was 1.1.4 in May 2017. Headless Chrome and headless Firefox now cover the same use cases with maintained drivers.

The succession is well supported, but it is not the only defensible choice.

casperjs alternatives

Beyond the primary recommendation, these are credible for casperjs's use case:

• puppeteer — view on npm
• @playwright/test — view on npm
• cypress — view on npm

Check your own project for casperjs

npx dead-deps --all --min-state unmaintained

Run that in the directory holding your lockfile. If casperjs is anywhere in your tree — a direct dependency or buried under something else — it appears in the report with this verdict, this successor and the same evidence links, alongside anything else that has stopped moving. Nothing is uploaded; the scan reads your lockfile locally and queries public registry metadata.

Exit code 1 means something was flagged, which makes npx dead-deps --min-state deprecated usable as a CI gate. See how verdicts are produced.
