Custom Module Development

Custom Drupal module development partner

When core and contrib won't cut it, DoodleWeb builds custom Drupal modules — clean, tested, upgrade-safe, and documented for your in-house team.

Short answer

Who builds custom Drupal modules?

DoodleWeb is a Drupal Certified Partner that builds custom Drupal 10 and 11 modules: integrations, custom entities, migration plugins and decoupled APIs. Every module ships with automated test coverage, inline documentation and a README your in-house team can maintain, and we check contrib first so you do not pay to rebuild something the community already supports.

What we build most often

Custom module work usually falls into a handful of categories, and knowing which one you are in shapes the estimate.

  • Third party integrations: Salesforce, HubSpot, Okta, payment providers, student information systems.
  • Custom entities and field types where content modeling exceeds what nodes and taxonomy handle cleanly.
  • Migration plugins for legacy field types during a Drupal 7 migration.
  • Decoupled APIs: JSON:API extensions and custom resources for React or Next.js front ends.
  • Editorial tooling: workflow additions, bulk operations, reporting views for content teams.

How we keep custom code upgrade safe

Custom code is a liability unless it is written to survive core releases. We target current APIs, avoid patching core, keep configuration in code, add automated tests that run in CI, and flag deprecations as part of every maintenance cycle so the work is spread out rather than deferred into a crisis.

Custom Module Development Drupal questions, answered

When is a custom Drupal module actually necessary?

When contrib genuinely does not cover the requirement, usually integrations with a system that has no Drupal module, custom entity types, migration plugins for legacy field types, or decoupled API resources. We evaluate contrib first and document why custom was needed.

Will custom modules block future Drupal upgrades?

Not if they are written correctly. We target current APIs, avoid core patches, keep configuration in code, and add automated tests so an upgrade can be verified rather than feared.

Do you contribute modules back to Drupal.org?

Where the work is generally useful and the client agrees, yes. Contributing reduces your long term maintenance burden because the community shares in supporting the code.

Can you review custom modules another team wrote?

Yes. Code review is a common starting engagement: security review, deprecated API scan, test coverage assessment and a prioritized remediation list.

What do we receive at handover?

Tested code in your repository, inline documentation, a README with local setup and deployment steps, upgrade sensitive notes, and a recorded walkthrough for your team.

Do you build decoupled Drupal APIs?

Yes. We extend JSON:API and build custom resources with a versioned contract, typed clients and editorial preview support for React or Next.js front ends.

A DoodleWeb product

Site Sonar
for your Drupal site

Your Drupal site already ranks. The question in 2026 is whether ChatGPT, Perplexity, Gemini, and Claude name you when a buyer asks their question. Site Sonar makes sure they do — and proves it with real Google Search Console and Analytics data.

1. Find the questions

The exact prompts your buyers ask AI

Built from your ICP, your buying committee's real questions, Google Search Console data, and live autocomplete. Not guesses — every tracked query shows where it came from.

2. Check the engines daily

ChatGPT, Perplexity, Gemini, Claude

SiteSonar runs your queries every day and records whether the engines name you, who they name instead, and which sources they cite as evidence.

3. Fix the gaps

The Content Gap agent drafts the answer

It scores how well your site answers each buyer question, writes the missing answer pages with FAQ + schema built to be quoted, and pushes them through your approval flow. Nothing publishes without a human yes.

4. Prove it moved

Real Google data, not our own scorecard

Google Search Console and Google Analytics are wired in, so you watch citations turn into impressions and into actual visits from chatgpt.com, perplexity.ai, and gemini.

Monitoring tools stop at the dashboard. SiteSonar acts.

It drafts the fix, publishes it to WordPress, GitHub, or any CMS, and re-checks until the citation appears.

Action-level guidance, not vanity scores

Example: "reply to this exact Reddit thread ChatGPT cites when answering your buyer's question" — with the link.

The 90-day guarantee

We lock your baseline in writing on day one. You see the number every month. If measurable AI visibility hasn't improved in 90 days, you don't pay. Nobody else in the category takes that risk.
