Updog and Dromo at a glance
| Dimension | Updog | Dromo |
|---|---|---|
| Data privacy | Files are parsed, validated, 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, so files never reach Dromo's servers. You opt into server sync 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, and a 14-day trial with no card when you go live. In production, a flat $19 per domain per month, the same at any volume, and your first paid domain includes a free one for staging. | 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. Updog keeps no mapping history. Your app owns that state and can supply saved selections on later imports. 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 | Cells edit inline through a typed editor per column, text, number, date, select, or multi-select, with clipboard, fill handle, and full undo and redo. Values pass a transform on the way in, then validation runs at three levels, built-in rules, your own checks, and asynchronous ones. Sorting, full-text search, filters on the columns you enable, and formulas. Invalid rows can block submit or come through flagged. Any view also exports in any supported format. | 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 one million rows at around 20 columns in the browser, with a filter on every column. No fixed row cap, the browser tab's memory is the ceiling, and fewer columns reach further. Filtering and sorting run in a worker, measured at 30 to 250 milliseconds over a million rows. | 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. Imports CSV, TSV, Excel, JSON, and XML, plus any other format through a parser you register yourself. | One SDK across React, Angular, Vue, and vanilla JS. Embeds via a JavaScript snippet. |
| Languages & RTL | English by default, with every interface 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. | 33 interface languages, set with a locale option. Arabic, Hebrew, Persian, and Urdu are not among them, and no right-to-left support was found. |
| Accessibility | An ARIA grid with full keyboard navigation and screen-reader support. WCAG 2.2 AA is the level Updog builds to, with automated rule checks over every component and every step of the importer on each test run. Updog holds no independent audit or VPAT. | No accessibility statement found. The review grid is Handsontable, which carries ARIA grid roles and keyboard navigation, its public pages list WCAG fixes in the column matching step, and validation errors can be stepped through with Alt and the arrow keys. |
Dromo offers both server-side sync and an in-browser Private Mode. This page reflects both. Facts checked against Dromo's public pages 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 to match your app's design exactly, styling the editor with your own CSS through variables and class overrides.
- You want to handle large files 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 that can run in the browser, but Updog is also a spreadsheet editor for existing data and runs only in the browser, while Dromo adds server-side sync, AI, and Headless processing.
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. Updog has no server mode at all; Dromo offers an opt-in server mode for its dashboard, webhooks, and API.
How does Updog pricing compare?
Updog is $19 per production domain per month, free in development, 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?
Yes, about 1 million rows in the browser, bound by the machine's memory. Dromo's browser imports handle several hundred thousand rows, with Pro capping at 100K per import and millions handled by server-side Headless processing.
Does Updog have built-in AI for mapping like Dromo?
No. Updog uses fuzzy column matching out of the box and lets you connect your own AI endpoint. Dromo includes built-in AI column mapping when server sync is on, plus plain-language cleanup.
How do the two handle accessibility?
Updog's grid uses ARIA semantics with full keyboard navigation and screen-reader support, and the importer is checked against WCAG 2.2 A and AA rules on each test run. Updog holds no independent audit or VPAT.
