The verdict in three sentences
An Arabic-first bilingual web app with proper RTL support costs, as a 2026 market ballpark, AED 220,000 to 600,000 in Dubai for an enterprise operations platform. Doing RTL properly adds 15 to 25 % to a single-language build, driven by mirrored layouts, Arabic typography, Hijri and Gregorian dates and bidirectional testing. Hosting and data handling should be decided early under the UAE PDPL and any sector or free zone rules that apply to you.
Arabic-first is a design decision, not a translation task
Many UAE enterprises, especially those serving government entities or semi-government clients, expect Arabic to be the primary experience, with English alongside. That means the Arabic layout is designed first and validated by Arabic-speaking users, rather than mirrored from an English mock-up at the end.
The tricky parts are well known: numbers, product codes, emails and Latin brand names stay left-to-right inside Arabic sentences; charts and timelines may or may not mirror; and documents such as invoices or approvals often need both scripts on the same page. Using CSS logical properties and a bidirectional-aware component library from day one keeps RTL close to the low end of the cost range.
| Element | English-only app | Arabic-first bilingual app |
|---|---|---|
| Layout | One direction | Mirrored layouts, validated in Arabic first |
| Typography | One Latin family | Arabic and Latin families tuned for screens |
| Dates | Gregorian | Hijri and Gregorian, user selectable |
| Numerals | Western digits | Western or Eastern Arabic digits by setting |
| PDFs and reports | Standard engine | Engine handling Arabic shaping and ligatures |
| QA | One reading direction | Both directions on every critical screen |
| Indicative extra cost | Baseline | 15 to 25 % |

On data protection, the UAE Personal Data Protection Law (Federal Decree-Law No. 45 of 2021) governs personal data processing onshore, while the DIFC and ADGM run their own data protection regimes. Sector rules, notably in health and financial services, can add localisation requirements. Many enterprises choose UAE-region cloud hosting to simplify procurement reviews; confirm your obligations with local counsel before signing the hosting contract.
As a nearshore benchmark, Kolonell's prices for a medium-complexity custom application run EUR 6,100 to 10,670 (4,000,000 to 7,000,000 FCFA), with the multilingual and RTL scope priced per language on top.

Chosen quote: AED 380,000, including AED 65,000 for RTL and AED 18,000 for translation. Before the project, two coordinators spent 7 hours a week each re-keying and translating work orders, about 56 hours a month at a loaded AED 120: AED 6,720 a month. Retiring two overlapping SaaS tools saves another AED 9,000 a month. Total monthly gain: AED 15,720, for a payback of roughly 24 months on visible costs, shortened by fewer errors on bilingual client reports.
FAQ
How much does a bilingual Arabic and English web app cost in Dubai?
As a 2026 market ballpark, AED 220,000 to 600,000 for an enterprise operations platform. Expect 4 to 6 months from discovery to launch.
How much extra does RTL add?
Around 15 to 25 % when planned from the start. Retrofitting RTL onto an English-only codebase can exceed 30 % because layouts must be rebuilt.
Do we need Hijri dates?
For government-facing or HR workflows, often yes. A dual calendar with user preference usually adds AED 8,000 to 20,000 depending on reporting needs.
Must the app be hosted in the UAE?
Not always under the PDPL, but sector rules and client procurement often favour UAE-region hosting. Budget AED 15,000 to 50,000 for setup and validate requirements with counsel.
Can we add French or Urdu later?
Yes, if internationalisation is structured cleanly: a third language typically costs 10 % or less of the initial build, mostly translation and QA.
