Pro / trial column applies during your 14-day trial and on paid Pro. Guest and Free use a faster sample preview (2 methods on samples). The 200-row upload cap applies only to Free (after trial) — not during your trial. Pro supports up to 10,000 rows. The preview table shows up to 2,500 rows; analysis always uses every populated row in your file.
How we compare on dataset size
Public limits from similar tools (2025–2026). CausalLens is optimized for analyst-sized CSVs today; hosted deployments will add async jobs for larger files.
| Product | Typical row limit | Notes |
|---|---|---|
| CausalLens Pro | 10,000 rows / file | All rows analyzed; scrollable preview up to 2,500 rows |
| CausalLens Free | 200 rows / file | Only after trial ends if you don't upgrade to Pro |
| CausoAI Starter | 10,000 rows | Free causal discovery tier |
| CausoAI Growth | 500,000 rows | Paid tier (~$299/mo) |
| QRY (file upload) | ~1 million rows | 100MB per-file cap |
| DoWhy / EconML (self-hosted) | No fixed cap | Limited by server RAM; millions need tuning |
| Warehouse-native (Statsig, etc.) | Effectively unlimited | Queries your Snowflake / BigQuery — not CSV upload |
The 200-row upload cap applies only after your 14-day Pro trial ends and you stay on Free without upgrading. During the trial you have the same 10,000-row limit as Pro. Pro supports up to 10,000 rows per file — every populated row is used in analysis (the on-screen table previews up to 2,500 rows for performance).
