Top 4 Mental Health & Therapy web developers in Marseille

In Marseille, a business website typically costs €5,000 – €20,000, while a custom web app runs €20,000 – €120,000. Agency day rates of EUR 55-120/hr are the main driver, followed by integrations and how much custom functionality you need. Tecklogist quotes mental health & therapy projects from from €799 at a fixed price.

A business website usually takes 3–6 weeks; a custom web app takes 8–20 weeks. Delays almost always come from late content, unclear scope or third-party integrations, so agree those before work starts.

The usual options are WordPress + end-to-end encrypted contact, Next.js + Sanity for group practices and Integrated booking: Calendly/Acuity/TheraPlatform. The right one depends on how often your team edits content, which systems the site must connect to and your budget, so be wary of any Marseille agency that recommends the same platform for every client.

Ask about practitioner-authored content with BACP/UKCP/APA registration numbers visible, Google's Quality Raters specifically check credentials on YMYL health pages; hTTPS everywhere with no mixed content warnings; accessible colour contrast and font sizing (WCAG 2.1 AA minimum). Then ask for two or three live mental health & therapy websites they built, who will actually work on yours, and what support looks like after launch.

This list is published by Tecklogist, and we rank ourselves first because mental health & therapy websites are core work for us: fixed prices, fixed timelines and code you own. The other Marseille agencies are ordered by the mental health & therapy evidence in their public profiles, and none of them pay to appear.
