Updog and Flatfile at a glance
| Dimension | Updog | Flatfile |
|---|---|---|
| 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. | Files are uploaded to Flatfile's servers to process. Flatfile acts as a data processor, with SOC 2 Type II, ISO 27001, GDPR, and CCPA compliance, a HIPAA-ready posture, and a DPA available. |
| White-label | Full styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one. | Theme the importer on every plan, within Flatfile's styling limits; remove Flatfile branding on the Professional plan and up. |
| 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. | Free for up to 50 files and 10M processed data values (the cells it reads) a month. Above that, usage-based pricing on files and data, pay-as-you-go or with volume discounts. |
| 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 code. Built-in AI column matching. Transforms values with code or AI. Casts values to your field types. Imports multiple files, with a dedupe plugin. |
| 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. | Inline validation and error highlighting, filter to problem rows, find & replace, bulk transforms, and version snapshots you can revert. |
| 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. | Large datasets on the server, with streaming advised above 500K 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. | JavaScript SDK, with React, Vue, and Angular wrappers. Renders its UI in an iframe. |
| 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. | 15 interface languages across 25 locales, with individual strings overridable. Its public translation repository holds no Arabic or Hebrew, 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. |
