I want to test some analytics tools properly, but I'm scared. Every "free trial" seems to need a credit card, and then you get auto-charged if you go over some invisible limit. Or they give you a tiny data allowance that's useless for real testing.
What's the actual strategy? How do you load real data and run real queries without a surprise invoice? I'm looking at tools for basic CRM and project tracking data. I don't need all the fancy features, just to see if it works and what it actually costs.
Hey! I'm Emma, a marketing ops manager at a mid-size e-commerce company (~300 employees). In prod, I run GA4 for web analytics, Metabase for internal reporting on our CRM and project data, and I've trialed Mixpanel and Amplitude for product analytics. So I've been through exactly this trial anxiety.
Here's my breakdown of the options for basic CRM and project tracking data, based on what I actually hit with each:
- Pricing model and the trial trap. GA4 is genuinely free with no credit card needed. But the catch is data retention - only 14 months for free. After that, you need Google BigQuery (which costs). Mixpanel's free tier gives you 100k monthly tracked users (MTUs) for life with no credit card. I ran three months of real user data and never got a bill. The guard is they cap your event collection if you exceed, not auto-charge. Amplitude's free tier is only 10k MTUs, which I burned through in a week. Metabase (open source) is free if you self-host; the cloud free tier supports up to 5 users but needs a credit card for sign-up - though they don't auto-charge.
- Data loading and setup effort. For CRM data already in a database, Metabase was the fastest. I pointed it at our Postgres instance and could run SQL queries in 15 minutes. No event instrumentation, no pipeline. GA4 was easy for web events but for CRM data you'd need to send server-side events or use BigQuery import - that took me a couple of days. Mixpanel and Amplitude both required SDK integration on our app and server - about a week of dev time for proper event tracking.
- Query performance on real data. With our ~500k CRM records, Metabase SQL queries ran under 1 second on indexed columns. On Mixpanel, I queried 2 million events for a funnel and it returned in 3-4 seconds on warm cache but about 8 seconds on cold. GA4's free query interface is limited - you can't write arbitrary SQL, only use their UI. For basic counts and trends it's fast, but any custom joins are impossible without export.
- Honest limitation for CRM data. GA4's data model is event-based, not great for account hierarchies or project status fields. I couldn't model "stage of deal" easily. Mixpanel and Amplitude are designed for user behavior, not static CRM objects - you can hack it but it's messy. Metabase is built for relational data, so it handles CRM tables naturally. Its limitation is no built-in attribution modeling - I had to do that in SQL manually.
- Support responsiveness on free tiers. GA4 - you get community help only. Mixpanel's free tier gave me email support within 24 hours on a billing question, which surprised me. Amplitude's free tier took 3 days to respond. Metabase self-hosted - no support, but the community is active and the docs are solid.
My pick: For basic CRM and project tracking data that's already in a database, start with a self-hosted Metabase. It's free, no credit card, full SQL access, and you control your data. For product analytics on user behavior from web or app, Mixpanel's free tier is the safest trial - generous cap, no surprise billing. To make the call clean, tell us: is your data sitting in a SQL database already, or do you need to ingest it from something like Salesforce or Jira? That changes which tool fits.
