ONLYOFFICE Docs, the self-hosted alternative to Zoho Office Integrator
Embed real-time document, spreadsheet, presentation, and PDF editing in your platform, without routing every document through another company's cloud.
Why developers look for a Zoho Office Integrator alternative
For platforms handling sensitive documents, watching per-document costs at scale, or wanting AI on their own terms, those trade-offs matter.
Billed per document opened ("API call"); cost scales with usage, not a flat infrastructure cost
No self-hosted or on-premise deployment, it's a cloud API service by design
AI is limited to Zoho's own built-in features; no way to bring your own provider or local model
White-labeling is a separate paid add-on
Documents are uploaded to Zoho's servers during editing (by Zoho's own description) even if your application and storage live elsewhere
What you get with ONLYOFFICE
Highest Microsoft Office compatibility
Built on Office Open XML, the same core format as DOCX, XLSX, and PPTX, so formatting stays intact with no lossy conversion.
Documents never leave your infrastructure
Self-host the entire editing service, so nothing routes through a third party's cloud.
Real-time collaboration, forms, and a full PDF editor in the same API
DOCX, XLSX, PPTX, PDF editing and co-authoring all come through one editing engine and one integration, instead of stitching together separate Zoho apps for each.
Open API and WOPI support, with SDKs for major languages
Integrate ONLYOFFICE Docs using the same open WOPI standard Zoho's own ecosystem relies on, plus open API and SDKs, so you're not locked into one language or framework.
AI on your terms
Any provider, including local models, not one fixed feature set.
Open-source code
The ONLYOFFICE source code is listed on GitHub under AGPL v.3.
No per-document billing
A free community edition (for open source projects) or predictable on-premise/cloud licensing, not a cost that scales with every document opened.
