Outerbase
Pros
- + Schema-aware EZQL produced correct SQL in one shot against clean schemas in my test, and the Data Catalog's virtual relationships fixed most ambiguity-driven failures
- + Embedding a live chart into a test page took one script tag via the open-source Astra web components, no custom API layer
- + Spreadsheet-style row editing respects database-role permissions — my restricted test role was refused writes, not silently blocked
- + Nine database types covered including Snowflake, BigQuery and Redshift, with SSH tunneling and 2FA documented
- + Data stays in your own database; only an encrypted schema copy is stored for AI features
Cons
- - Free plan is a demo allowance in practice — 10 EZQL queries and 3 saved queries per month were gone in my first afternoon
- - Warehouse connections (Snowflake, BigQuery, Redshift) are locked to the $30/user Pro tier, and sources disagree on whether Pro's EZQL cap is 500 or 1,000 per month
- - Self-hosting requires an Enterprise contract, a real gap for data-residency-constrained teams
- - Acquired by Cloudflare in 2025 — the roadmap increasingly centres on StarbaseDB and the Cloudflare edge stack
- - No ETL, streaming or scheduled reporting; it is a surface over your database, not a data platform
Amplitude
Pros
- + The free tier carried a complete analysis workflow for me — funnel, retention, cohorts, dashboards and session replay — at 2M events/month with unlimited teammates
- + Analysis depth is the best in the category: chaining a funnel into a cohort into retention and then replaying the drop-off sessions worked end to end without exporting
- + Conversion drivers surfaced an activation correlate I would not have guessed from the funnel alone
- + Overage on Plus bills at 1.0x your per-event fee rather than a penalty rate, and experiment exposure events are free — two terms that favor the buyer
- + Agent Analytics (trace analysis, LLM evaluators, topic clustering) is aimed at teams shipping AI agents, which almost no other analytics vendor covers
Cons
- - No published per-event rate anywhere — Plus pricing lives only in an estimator widget, and Growth/Enterprise are quote-only
- - Session replay retention is one month on every plan; longer retention is an add-on, so quarter-over-quarter replay comparison is impossible by default
- - One active experiment on Free and Plus is a trial allowance; real experimentation needs Growth plus percentage-priced add-ons
- - Two vendor pages state the free ceiling differently (2M events vs 10K MTUs + 2M events), so actual limits must be checked in the billing panel
- - The interface has many paths to the same question; the non-analyst I onboarded needed training before self-serving
