Updog and ImportOK at a glance
| Dimension | Updog | ImportOK |
|---|---|---|
| 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. | Marketed as client-side, with nothing sent to its servers, records delivered to your own API, and a blog post saying its AI runs in the browser. Its terms state the service is not tailored to industry regulations such as HIPAA. The Cyprus-based company's privacy policy covers the account and usage data it collects, separate from the imported rows. |
| White-label | Full styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one. | Restyled with your own CSS rules passed to the wizard through class overrides. Branding is removed on every paid plan. |
| Pricing | Free for development. In production, a flat $19 per domain per month, the same at any volume. | Public and self-serve, billed yearly or as a one-off: Pro 149 EUR/year, Growth 299 EUR/year, a custom Scale tier, and a one-time 299 USD lifetime plan. A free tester runs up to 20 records per import. Imports are unlimited with no per-import fees. |
| 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 is defined in code. Columns auto-match by fuzzy name matching, or by AI on a paid add-on. Values map to your options through providers and transformers, and configured transformers convert dates and numbers. Multiple sheets are supported, and a validator flags duplicate 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. | Validators cover required, unique, type, email, length, range, and list membership, plus custom and whole-dataset rules, and can run async. Transformers chain to trim, reformat, find and replace, and merge or split fields. A spreadsheet editor with filtering and live validation lets users fix data inline. |
| Scale & performance | About 1M rows (at around 20 columns) in the browser, bound by the machine's memory. | Runs in the browser and handles files of up to two million rows, bound by memory, with the docs recommending you split the largest files into batches. |
| Integration | React component, plus a Web Component for Vue, Angular, Svelte, and vanilla JS. Renders inline in your page's DOM. | A web component with React, Vue, and JavaScript packages, plus Next.js, Angular, and vanilla examples, rendered inline. It delivers records to your own API through callbacks, and a file can be passed in to skip the upload screen. |
| 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. | Six built-in interface languages, and you can add your own translations for others. |

Questions people ask
Is Updog a drop-in replacement for ImportOK?
No. Both embed an import wizard that posts to your own API, and both include a data editor. Updog's can also be used on its own as a standalone spreadsheet editor, without an import.

Neither sends imported rows to a vendor server. Updog has no server mode at all; ImportOK delivers records to your own API and markets in-browser processing.
How does Updog pricing compare?
Updog is a flat $19 per production domain a month, free in development. ImportOK bills yearly from 149 EUR, or once at 299 USD for lifetime access.
