Heap
Pros
- + Retroactive event definitions over auto-captured data: I defined a virtual event against existing interactions and it populated historically — no instrumentation ticket, no waiting for the next release
- + A real free plan covers evaluation properly: up to 10K monthly sessions with core charts, six months of history and SSO, where I built a working funnel and retention chart
- + Enrichment joins third-party firmographic data into captured events, and the free plan lists unlimited enrichment sources
- + The Sense assistant (Growth+) quantified impact on a conversion step I was investigating, cutting the manual comparison work
- + Contentsquare integration lets teams jump from a Heap funnel into zoning, replay and frustration signals in the parent platform
Cons
- - Session replay, error analysis and heatmaps are a paid add-on (Experience Analytics) rather than included, while Mixpanel and Amplitude bundle 10K replays on free plans
- - Auto-capture noise is structural: the first sessions I analyzed were mostly event-sorting overhead before the data became legible
- - No published pricing beyond the free plan — Growth shows a signup estimate and Pro/Premier are sales conversations, which I could not verify to a current number
- - Free plan caps at 6 months of data history and 10K monthly sessions; sessions are also the wrong billing unit for high-traffic content sites
- - EU data residency and region-specific storage are Premier-only, which rules out the lower tiers for some European buyers
ChartMogul
Pros
- + MRR movements reconciled exactly month to month in my testing — new, expansion, contraction and churn lines summed to the reported change with no manual corrections on a Stripe setup
- + Free up to $10K MRR with the full metrics model included, which makes it the obvious starting point for pre-$10K-MRR SaaS
- + The per-customer MRR table shows annual normalization, proration and exchange-rate impact as visible lines instead of burying them in a total
- + Segmentation goes deep with custom sources — I built an LTV-by-acquisition-channel report by joining external lead data, which flat metrics tools cannot do
- + REST API, MCP server and CSV access on every plan, so the data is yours to move even at the free tier
Cons
- - Pricing scales with ARR tracked: the analytics bill grows exactly when the business does, reaching the high hundreds per month by $5M ARR
- - Starter allows only one billing system and three team members, so any multi-system revenue setup forces Pro
- - Accounting connections run through a partner (SaaSync) with a manual review queue for invoices the system cannot parse
- - Forecasting is limited to the AI assistant's projections; serious planning needs a warehouse or BI export on Pro and above
- - Third-party review sites still publish outdated plan names and prices — only the vendor pricing page reflects the current Starter/Pro/Enterprise tiers
