Updog and OneSchema at a glance
| Dimension | Updog | OneSchema |
|---|---|---|
| Data privacy | Files are parsed and edited in the browser. Row data never reaches Updog's servers, so there is no data processor, DPA, or residency to manage. | Files upload to OneSchema's servers to validate and transform. SOC 2 Type II, SOC 3, GDPR, CCPA, and HIPAA compliant, with AES-256 at rest. Retention defaults to 7 days and is deletable via API. Regional hosting in the US, EU, Canada, and Australia. |
| White-label | Full styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one. | Branding Suite with 20+ options: brand color, custom fonts, button styles, and upload imagery. Removing the OneSchema logo and full white-label come with the Pro tier. |
| Pricing | Free for development. In production, a flat $199 per domain per month, the same at any volume. | Sales-led and quote-based, not published. Three tiers (Starter, Pro, Enterprise) with file-upload caps and custom file-consumption packages, set per deal after a demo. |
| Data mapping | Schema in code. Fuzzy column matching with a built-in synonym dictionary you can extend, or connect the AI your organization already approves through a hook, so it runs on infrastructure you control with no new AI vendor to clear. Maps incoming values to your options. Auto-detects number and date formats. Combines files by upserting on a key. | Templates built in a dashboard or via API. Intelligent column mapping learned from historical mappings across its user base, plus OneSchema AI. Normalization library for dates, numbers, and addresses. Codehooks split columns and merge rows. |
| Data cleaning | Inline validation and error highlighting, filter to problem rows, find & replace, bulk transforms, and full undo/redo, so everything can be fixed without leaving the editor. Any view also exports in any supported format, if a user would rather fix outside. | Inline validation with one-click autofix, find & replace, and bulk edits. Webhook validation against your backend. Users can export an annotated Excel of flagged rows to fix outside the importer. |
| Scale & performance | About 1M rows in the browser, bound by the machine's memory. | Large files on the server. Pro handles spreadsheets up to 10M rows; Enterprise adds custom Rust servers for 10M+. |
| Integration | React component, plus a Web Component for Vue, Angular, Svelte, and vanilla JS. Renders inline in your page's DOM. | JavaScript SDK, with React, Angular, and Vue wrappers. Drops in as a modal rendered in an iframe. |
| Accessibility & RTL | Built on an ARIA grid with full keyboard navigation and screen-reader support. English by default, with every UI string overridable, so you can localize into any language. Right-to-left is first-class: it flips layout, text alignment, scrollbars, and column pinning, and carries through to export. | Publishes an accessibility statement: partially conformant with WCAG 2.2 AA (self-assessed, 2025), optimized for desktop, with a VPAT on request. Offers Arabic translation. |
OneSchema repositioned around AI data operations (FileFeeds) in 2025, with the embeddable importer as one product. This page compares that importer, the closest match to Updog. Facts checked against OneSchema's public pages and docs in June 2026.
Which one fits your team
OneSchema may fit better if
- You want a hosted, server-side importer with compliance certifications (SOC 2, HIPAA) and a DPA.
- You need data work beyond importing, like OneSchema's FileFeeds for ongoing SFTP, API, and PDF integrations.
- You want validation and transforms to run on the server, with regional hosting or a self-hosted deployment.
- You're fine with sales-led, quote-based pricing that scales with file volume.
Updog may fit better if
- You want an importer and spreadsheet editor embedded in your own app.
- You want file data processed in the browser, with nothing stored on a server.
- You want flat, public pricing with no per-import fees.
- You want to use the AI your organization already approves, with no new vendor to clear.
Questions people ask
Is Updog a drop-in replacement for OneSchema?
No. Both embed an importer, but Updog runs in the browser inside your app's DOM, while OneSchema is a hosted importer rendered in an iframe modal, backed by server-side processing and a broader AI data platform. Updog fits if you want importing and editing inside your product. OneSchema fits if you want a hosted importer with server-side validation and file integrations.
Does Updog store my users' data the way OneSchema does?
No. Mapping, validation, and editing all run in the browser. File data is never sent to Updog servers. OneSchema uploads files to process them and retains them by default for 7 days, configurable and deletable via API.
How does Updog pricing compare?
Updog is $0 for development and $199 per production domain per month. Every feature is on every plan, with no per-import fees. OneSchema is sales-led and quote-based across Starter, Pro, and Enterprise tiers, with caps on file uploads.
Can Updog handle large files like OneSchema?
Updog handles about 1 million rows (at around 20 columns) in the browser, bound by the machine's memory. That covers parsing, mapping, validation, editing, and export. OneSchema processes larger files on the server, with Pro up to 10M rows and Enterprise beyond that on custom Rust servers.
Can it be used to view or edit existing data, without an import?
Yes. Load existing data straight into the editor and users can view and edit it, with a read-only mode available. OneSchema is built around the import-and-validate flow rather than general spreadsheet editing.
Is Updog accessible, and does it support right-to-left languages?
Yes. Updog's grid uses ARIA semantics with full keyboard navigation and screen-reader support, and renders right-to-left layouts natively. OneSchema goes further on documentation, with a published statement noting partial WCAG 2.2 AA conformance (desktop-optimized) and a VPAT on request. It also offers Arabic among its translations.
