Find the extension for the next job on your site

Find an extension for your project, then check its compatibility, support and licence terms. Capell Foundation packages use the MIT licence and are available from public Packagist releases. Check each listing for availability; Beta requires explicit opt-in and Labs is not a current install choice.

What this catalogue gives you Show details

  • One publisher, not a reseller shelf

    Capell writes, releases, and supports every listing on this page. One licence document, one support address, one changelog — there is no third-party vendor to chase when a release needs a fix.

  • Each release carries its own review record

    A listing shows the exact version that was reviewed, the approval date, and the stages behind it: automated tests, AI-assisted analysis, then human sign-off over security, compatibility, public output, and package boundaries.

  • Every suite shows its members and their prices

    Every suite page lists the extensions it contains and the total of their prices when bought one at a time, next to the suite price. Compare the two before you choose.

  • One upgrade cadence across the set

    Extensions are released against the same Capell core version, so a single composer update moves the whole set. Each listing states its tested Laravel, Filament, and Capell versions.

Suites for jobs that need several extensions

Compare grouped buyer paths for work such as editorial foundations, media operations, and site navigation. Check the bundle price and each included extension before buying.
