What are legacy apps?
Legacy apps are the business applications your teams rely on, not your core systems of record. They were built on aging technology like:
Some run standalone and others connect to your core systems—but all of them run real processes every day.
How legacy apps slow the business down
These apps still work, but the stack underneath holds the business back.
Rewriting legacy apps takes months, or sometimes years
Modernization programs run into the same execution problems, every time.
Build AI-native apps on a dedicated platform
Rebuild legacy applications as modern, AI-native apps on Zoho Creator. AI-powered low-code development compresses the rebuild from months to days, so modernization moves at the speed the business needs.
Reimagine legacy apps as AI-native
Modernizing a legacy app isn't about rebuilding the same thing on a newer stack. It's about reimagining how the app should work today, with capabilities the original stack could never support.

AI at the core
Document processing, intelligent agents, predictions, and automation built into how the app actually works

Mobile and offline by default
Field teams, frontline workers, and remote users with full access, not a stripped-down view

Modern UI and UX
Designed for how people work today, on the devices they actually use

Connected to your stack
Integration with 1,000+ apps through prebuilt connectors, APIs, OData, and on-premises bridges
Common legacy stacks Creator helps modernize
Most enterprises have a mix of these. Each carries its own constraints — and each rebuilds well on Creator.
| Legacy stack | Typical applications | Rebuilt on Zoho Creator as |
|---|---|---|
| Lotus Notes / HCL Domino | Workflow apps, document approvals, internal request tools, departmental databases | Modern workflow apps with mobile access, AI-assisted routing, and native integration to current systems |
| Microsoft Access | Departmental databases, tracking tools, internal reporting apps | Centralized cloud apps with multi-user access, audit trails, and proper governance |
| Oracle Forms | Operational apps, data entry interfaces, internal portals built around Oracle databases | Web & mobile apps that retain the data layer but modernize the interaction layer |
| Excel & VBA | Approval trackers, intake forms, calculation tools, planning sheets | Controlled apps with permissions, automation, and AI-driven processing |
| .NET legacy (WinForms, classic ASP) | Internal portals, line-of-business tools, custom utilities | Cloud-native apps with modern UI, mobile access, and built-in AI capabilities |
| SharePoint on-premises | Workflow apps, document-driven processes, team portals | Modern apps with cleaner workflows, mobile-first access, and integration to the broader stack |
Built for legacy modernization at enterprise scale
Modernization rarely stops at one app. It often spans dozens, with each rebuild needing speed, AI, integration, and enterprise control. Creator brings it all together.

AI-powered development
Visual development and AI-assisted building turns a months-long rebuild into weeks.

Instill AI in every app you build
Embed OCR, document extraction, intelligent agents, predictions, and automation into how each rebuilt app works. It's all powered by Zia, Zoho's AI engine, and available across every app on the platform.

One platform for the whole portfolio
Standardize the entire modernization program on a single platform. Every rebuild compounds on the last, instead of creating a new fragmentation problem across multiple tools.

Broad integration support
Connect to the systems the rebuilt apps depend on through 1,000+ prebuilt connectors, APIs, OData, and webhooks. Easily build custom integrations for everything else.

Governance and access controls
Utilize role-based access, SAML-based SSO, audit trails, and activity monitoring for IT-governed development.

Built to scale
Creator handles enterprise workloads across geographies, with no infrastructure overhead for IT teams to manage.
Security, privacy, and compliance
Enterprise-grade protections for data, infrastructure, and operations.
