Updog and UseCSV at a glance

|---|---|---|

Row data never reaches Updog's servers, so there is no data processor, DPA, or residency to manage. | Frontend callback mode processes data in the browser, with nothing sent to UseCSV's servers. Webhook mode sends import data to its servers, kept up to 24 hours, with only metadata retained after. GDPR compliant, hosted on Vercel and PlanetScale, with no SOC 2 audit of its own. |
| White-label | Full styling through CSS variables and class overrides. No Updog logos or "powered by" on any plan, including the free one. | Custom styling and branding removal available across tiers. |
| Pricing | Free for development. In production, a flat $199 per domain per month, the same at any volume. | Public and tiered by imports and rows. Free Hobby (50 imports, 10K rows). Starter $49, Plus $99, Pro $199 (2,500 imports, 500K rows). Enterprise is custom for 1M+ rows and a DPA. |
| 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. | Columns and validation rules set in a no-code dashboard or in code. Automatic column-name matching. Validation hooks for custom checks. |
| 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 spreadsheet editor to fix errors, data healing for common issues, and validation hooks that flag rows against your configured rules. |
| Scale & performance | About 1M rows in the browser, bound by the machine's memory. | Browser-based, with per-tier row caps from 10K up to 500K, and 1M+ on Enterprise. |
