Instant Preview URLs
Every deployment gets a unique live preview URL — share changes with stakeholders and clients for review before a single line reaches production.
Free SSL + Custom Domains
Every app gets an auto-provisioned SSL certificate at no cost. Map your brand domain in the console and Catalyst handles certificate issuance and automatic renewal.
Can I map my custom domain to an application deployed with Catalyst Slate?
Absolutely! Catalyst Slate allows you to easily map custom domains to your deployed applications, giving you full control over your brand and online presence. Configure two CNAME records with your DNS provider, and Zoho provisions a free SSL certificate within 48 hours — fully automated from that point on.
How are environment variables managed for applications on Catalyst Slate?
Catalyst Slate allows you to manage environment variables seamlessly. Define them directly in the Catalyst console with secure, encrypted storage — ensuring clean separation between development, staging, and production configurations without ever hard-coding sensitive values in your codebase.
React in Real-Time with Catalyst Signals
Modern applications don't poll — they react. Catalyst Signals is an enterprise event bus that connects your entire Zoho ecosystem, routes events intelligently through filters and transformations, and triggers downstream actions in near real-time without a single line of polling code.
Pre-built Zoho Publishers
CRM, Books, People, DataStore, Cache — dozens of Zoho services come pre-wired as event publishers with zero setup on your end.
Smart Event Routing
Filter by conditions, extract specific fields, and transform payloads before they reach any target — full control without extra code.
Reliable Delivery
Configurable retry policies, rate-limit handling, and flexible batch dispatch ensure no event is ever silently dropped under load.
Full Observability
The Event Logger gives you complete visibility into every event's lifecycle — track, debug, and replay any event flow from the console.
Enterprise AI, Ready Out of the Box
Stop waiting for a dedicated data science team. Catalyst Zia Services and QuickML put production-grade AI capabilities directly into your application — via a few SDK calls, or no code at all.
AutoML & QuickML
Build no-code machine learning pipelines that train on your data and deliver accurate predictions — from data ingestion to deployed model in a single visual canvas.
Text Analytics
Automatically classify customer sentiment, extract named entities, and surface key insights from any text — ideal for tickets, reviews, and live CRM enrichment.
OCR & Document Intelligence
Digitize printed and handwritten documents, extract structured data from invoices, ID cards, and forms — eliminating manual data entry at enterprise scale.
Image & Object Analysis
Detect faces, recognize objects, scan barcodes, and moderate images for unsafe content — all via simple API calls with no model training required on your side.
Automate the Routine. Focus on What Matters.
Catalyst Job Scheduling lets us automate any recurring operational task — nightly report generation, data sync jobs, maintenance routines — with precision control over timing, retry behavior, and failure alerting.
Pre-defined & Dynamic Crons
Schedule jobs on a fixed calendar or create them dynamically at runtime — your automation adapts to real-world conditions, not the other way around.
Multi-Target Execution
Trigger Catalyst Functions, kick off a Circuit workflow, invoke an AppSail microservice, or call any third-party Webhook — from a single unified scheduler.
Failure Alerting
Configure application alerts that fire instant email notifications on delays, failures, or missed executions — nothing silently breaks in production.

Frequently Asked Questions
What is Zoho Catalyst and why build enterprise web applications on it?
Zoho Catalyst is a fully managed serverless cloud platform that sits natively within the Zoho ecosystem. It gives Wanas Apps a production-grade environment — auto-scaling compute, managed CDN, and built-in Zoho API access — to build custom SaaS platforms, client portals, and deep ERP extensions without requiring separate cloud infrastructure. Because Catalyst shares the same security boundary and identity as your other Zoho apps, integrations are native rather than bridged through third-party middleware. The result is faster development, lower hosting cost, and simpler long-term maintenance for companies already invested in Zoho.
What types of web applications does Wanas Apps develop?
Common build types include: client-facing self-service portals (contract review, invoice approval, project status dashboards); operational dashboards that pull live KPIs from Zoho CRM, Books, and Inventory; custom order-management or booking flows integrated with Zoho Inventory and Zoho Books; and middleware that connects Zoho to external systems such as ERP platforms, payment gateways, or national e-invoicing portals. If the application needs to extend, mirror, or automate something the Zoho ecosystem does not do out of the box, Catalyst is the right platform.
How does a Zoho Catalyst application compare to a build on AWS or Azure?
For companies already running Zoho, Catalyst dramatically reduces infrastructure overhead — there are no separate server deployments, billing accounts, or custom Zoho authentication layers to maintain. Catalyst auto-scales, handles SSL and CDN, and allows native Zoho API calls using your existing Zoho credentials. The practical tradeoff is that a Catalyst application is tied to the Zoho ecosystem. For applications requiring complete vendor independence, or workloads that genuinely need services such as GPU compute or highly specific database engines, a standalone cloud build may be more appropriate. Wanas Apps evaluates both paths during the discovery phase and recommends based on your actual requirements.
How long does a custom web application project take?
A clearly scoped portal with defined integrations typically takes 6–12 weeks from signed brief to production launch. More complex multi-module platforms with custom workflows and external API integrations typically run 3–6 months. Wanas Apps delivers in two-week sprints with a working review build at the end of each cycle, so you see real, tested progress throughout — not a big-bang delivery at the end.
What support is included after the application launches?
All production applications include a 30-day go-live stabilisation period at no additional cost. Beyond that, Wanas Apps offers monthly retainer agreements covering ongoing feature additions, security patching, Zoho version compatibility updates, and performance monitoring. The same team that built the application continues to maintain it, so institutional knowledge of your codebase stays with the people maintaining it.
Common Questions
What is custom web application development and how does it benefit UAE businesses?
Custom web application development means building software tailored precisely to your business processes rather than adapting workflows to off-the-shelf tools. For UAE businesses, this often means Arabic-language interfaces, UAE VAT 5% and Corporate Tax 9% calculation built-in, and seamless integration with local payment gateways. Wanas Apps engineers these solutions on Zoho Creator and Catalyst — Zoho's enterprise cloud platform — so they sit natively within your existing Zoho ecosystem.
What is Zoho Creator and how does it accelerate business app development?
Zoho Creator is a low-code application platform that lets Wanas Apps build fully functional business apps — forms, workflows, reports, and integrations — in a fraction of the time of traditional development. It connects natively to Zoho CRM, Books, Inventory, and People, making it the fastest path to a custom portal for companies already on Zoho. Typical applications include client self-service portals, field service management tools, approval workflow apps, and custom order-management systems.
How much does custom web app development cost in the UAE?
Zoho Creator-based applications start from approximately AED 10,000–25,000 for a defined-scope portal or workflow app, while full Catalyst SaaS platforms with external integrations typically range from AED 40,000–150,000+. As a certified Zoho Premium Partner, Wanas Apps provides AED-denominated fixed-price proposals after a paid discovery workshop so you have a firm budget before development begins. Ongoing Zoho Creator licensing is included in the standard Zoho One or Creator subscription you likely already hold.
How long does a custom web application project take in Dubai or Riyadh?
A scoped Zoho Creator application typically takes 4–8 weeks from signed brief to production launch. More complex Catalyst platforms — multi-tenant SaaS, third-party ERP integrations, or national e-invoicing connectors — typically run 3–6 months. Wanas Apps delivers in two-week sprints with a working review build each cycle, giving UAE and KSA stakeholders live visibility throughout the project rather than a big-bang handover.
Is Zoho Creator compliant with UAE VAT and Saudi ZATCA e-invoicing requirements?
Zoho Creator applications built by Wanas Apps are engineered with local compliance from the ground up — UAE VAT 5% rules, Corporate Tax 9% grouping logic, and Saudi Arabia ZATCA Phase 2 e-invoicing integration are standard design considerations, not afterthoughts. Our team has delivered compliance-critical portals for businesses operating across the UAE and KSA, and we include regulatory review as part of every discovery phase for financial or HR workflow applications.
