Updog and Dromo at a glance
| Dimension | Updog | Dromo |
|---|---|---|
| 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. | Defaults to in-browser processing (backendSyncMode DISABLED), so files never reach Dromo's servers. You opt into server sync (FULL_DATA) to enable the dashboard, webhooks, API, and AI auto-mapping. SOC 2 Type II, HIPAA, and GDPR, with bring-your-own-storage and custom retention on Enterprise. |
| White-label | Full styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one. | Full style overrides and white-label included on every paid plan. |
| Pricing | Free for development. In production, a flat $199 per domain per month, the same at any volume. | Public pricing. Free sandbox for development. Pro is $599 a month for 250 imports, then $3 per import over. Enterprise is custom with unlimited imports. |
| 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. | Schema in a no-code Schema Studio or in code. Fuzzy header matching client-side; AI auto-mapping when server sync is on. Lifecycle hooks for custom logic. |
| 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. | Real-time validation with type, regex, and custom rules. An error navigation panel for inline fixing. Invalid rows can block submit, be removed, or be included. Plus AI-assisted cleanup in plain language. |
| Scale & performance | About 1M rows in the browser, bound by the machine's memory. | Browser imports handle several hundred thousand rows; Pro caps at 100K rows per import. Enterprise Headless processes files server-side, up to 10M+ rows. |
| Integration | React component, plus a Web Component for Vue, Angular, Svelte, and vanilla JS. Renders inline in your page's DOM. | One SDK across React, Angular, Vue, and vanilla JS. Embeds via a JavaScript snippet. |
| 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. | Highlights errors inline with a review screen for fixing flagged rows. Localized into more than 30 interface languages, with no right-to-left support found. |
Dromo offers both server-side sync and an in-browser Private Mode. This page reflects both. Facts checked against Dromo's public pages and developer docs in June 2026.
Which one fits your team
Dromo may fit better if
- You want a choice of server-side sync (dashboard, webhooks, API) or in-browser Private Mode in one product.
- You want built-in AI mapping and plain-language cleanup, rather than bringing your own AI endpoint.
- You need server-side Headless processing or self-hosting for files in the millions of rows.
- You're focused purely on importing and want a tool that does only that.
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 Dromo?
No. Both are embeddable importers, and both can run in the browser. Updog is also a spreadsheet editor for viewing and editing existing data, and runs only in the browser. Dromo is import-focused and adds server-side sync, AI, and Headless processing. Updog fits if you want importing and editing inside your app. Dromo fits if you want a dedicated importer with server-side options.
How do the two handle data privacy?
Both process file data in the browser by default, so in that mode neither sends row data to its servers. Dromo also offers an opt-in server mode for its dashboard, webhooks, and API. Updog has no server mode.
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. Dromo is free to start, then $599 a month for 250 imports with $3 per import over, and custom Enterprise pricing.
Can Updog handle large files like Dromo?
Updog handles about 1 million rows (at around 20 columns) in the browser, bound by the machine's memory. Dromo's browser imports handle several hundred thousand rows, with Pro capping at 100K rows per import. For files in the millions of rows, Dromo uses server-side Headless processing.
Does Updog have built-in AI for mapping like Dromo?
Updog uses fuzzy column matching out of the box and lets you connect your own AI endpoint, so you can use the AI your organization already approves instead of clearing a new vendor. Dromo includes built-in AI column mapping (when server sync is on) and plain-language cleanup.
Is Updog accessible, and does it support right-to-left languages?
Yes. The grid is built on ARIA semantics with full keyboard navigation and screen-reader support, and right-to-left is first-class, flipping layout, alignment, and column pinning. Dromo highlights errors inline with a review screen for fixing flagged rows, and is localized into more than 30 interface languages, with no right-to-left support found.
