Why teams choose SourceMedium over Glew

Glew's tier-gating is the core issue. On Glew Pro, you get 40 integrations and no warehouse access. Want the full 170+ integrations, SQL, warehouse, or custom metrics? You need Glew Plus — which has custom pricing and bundles a Looker dependency you may not want. SourceMedium includes everything on every plan.

Where the approaches differ

All-inclusive vs tier-gated: Glew Pro limits you to 40 integrations, no warehouse access, and basic segments. Full capabilities require Glew Plus at custom pricing with a bundled Looker license. SourceMedium includes full SQL access, all 40+ integrations, and custom metrics on every plan.

No data freshness SLA: Glew doesn't publish when your data was last updated. G2 reviews cite manual refresh complaints. SourceMedium provides reconciled daily data with documented lineage — you always know how current your data is.

Historical data retention: Glew limits warehouse data to "up to two years." SourceMedium provides full historical backfill with no retention limits — your multi-year cohort analyses and seasonal trend studies aren't artificially capped.

Looker dependency: Glew Plus bundles Looker for custom reporting, adding a third-party BI tool to your stack. SourceMedium provides built-in dashboards, SQL access, and an AI analyst — no external BI tool required.

When Glew might be the better fit

Glew Plus works for brands that already use Looker and want prebuilt LookML dashboards without building from scratch. The 250+ KPI library provides broad metric coverage out of the box — useful if pre-built KPIs match your exact needs.
