How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- OpenObserve (Per Usage) — OpenObserve bills purely on usage — $0.50/GB ingest + $0.01/GB query (30% off annual, no per-seat fees). There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Whalesync (Per Usage) — Whalesync bills on usage — Records in sync on top of a paid plan starting at $40/mo. The plan includes an allowance; anything beyond it is metered.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
OpenObserve is a Datadog/Splunk/New Relic alternative positioned on transparent pay-as-you-go pricing with no per-seat or per-host fees. Cloud PAYG: $0.50/GB ingestion + $0.01/GB query (30% off with annual commit). Includes 15-month metrics retention + 30-day non-metrics retention default. Enterprise adds SSO/RBAC, AI SRE agent, BYO bucket infinite retention. Self-hosted OSS is free; Self-hosted Enterprise free up to 50GB/day.
Two-way database sync between no-code tools (Airtable ↔ Webflow ↔ Supabase ↔ Notion ↔ HubSpot). Positioned as the alternative to running one-way Zapier automations for keeping two data sources in lockstep. Distinctive for solving the specific pain of 'CMS collection needs to match Airtable base but also flow back'. Restructured 2026: retired the $5 Personal tier, now starts at Starter $40/mo (1,000 records in sync). Higher tiers (Plus, Pro) use a records-based slider with prices scaling to $200+/mo. Enterprise custom. YC-backed. Popular with no-code agencies building client sites and startups syncing CMS to Webflow/WordPress.

What each is best for
OpenObserve is worth it if… OpenObserve is ideal for teams migrating off Datadog, Splunk, or New Relic who want radically transparent pay-per-GB pricing with no seat fees. Best if your telemetry cost is dominated by log and metric volume rather than user count.
Whalesync is worth it if… ops-savvy teams that need two-way sync between databases (Airtable, Notion, HubSpot, Postgres, Google Sheets) — particularly for teams building internal data pipelines without hiring engineers. Starter covers core no-code connectors (1,000 records); Plus adds CRM connectors (Attio, HubSpot, Pipedrive); Pro adds all connectors including Salesforce + Affinity.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
