Which one fits you.
Pick Amplitude if
You have people whose job is analytics, and you want experiments, flags and cohorts in one place.
- You run A/B tests and ship behind feature flags every sprint
- Someone owns your event plan and keeps it clean
- You fit in the free plan and have time to learn the tool
Pick GrainQL if
You have no analyst, and you need to know why conversions dropped before the week is over.
- Nobody on your team has analyst in their title
- You want the cause and the recordings, not a chart to read
- You want a bill that stays the same when you track more
What actually differs.
Three situations where the choice shows.
A platform to run, or a question to ask.
It is Monday. Signups are down and you have one hour before the team call. Nobody on the team has analyst in their title.
Amplitude
Amplitude gives you analytics, experiments, flags, guides, surveys and AI agents in one product. That breadth pays back a team that takes the time to learn it and set it up well.
GrainQL
GrainQL does one job: it finds where your site loses money. Ask Neo why signups dropped. Neo names the cause in about 3 seconds and attaches the session recordings.
Who notices the drop first.
Checkout broke on mobile on Thursday night. You found out on Monday, when someone opened a dashboard and saw the dip.
Amplitude
Amplitude has alerts on paid plans and agents you can put on a schedule. Someone decides what to watch and sets it up, which works well when a person owns that job.
GrainQL
Neo sends a daily digest and flags drops and spikes without being asked. Nobody has to choose the metrics first. Ask Neo about a flag and you get the cause with the recordings.
Billed by events, or by visitors.
You want to track ten more buttons before a launch. Then you stop and wonder what that does to next month's bill.
Amplitude
Amplitude counts events. The Free plan covers 2 million a month, and Plus scales with event volume up to 70 million. More tracking and more traffic both add events.
GrainQL
GrainQL counts monthly visitors, with unlimited events per visitor and no overages. Tracking more buttons does not change the price. Plans start at $29 a month.
Row by row.

What it costs.
If you fit in 2 million events a month, Amplitude costs less, and the case for GrainQL is the time you save, not the price.
Amplitude
Amplitude bills by event volume, and 2 million events a month are free with no time limit. Plus starts at $0 and scales with volume, and Growth and Enterprise are custom quotes.
GrainQL
From $29 a month for 50,000 monthly visitors. Billed by visitors, with unlimited events per visitor. Every feature is on every plan.

Fair is fair.
Experiments and feature flags.
Amplitude runs A/B tests, web experiments and unlimited feature flags next to the analytics. GrainQL has no experimentation suite and no flag platform.
A free plan with real room.
Amplitude's Free plan has 2 million events a month, session replay and AI agents, with no time limit. GrainQL has a 14-day trial and no free plan.
Depth, governance and scale.
Amplitude has deep cohorts, project permissions, role-based access and a warehouse-native option. If an analyst will use all of that, stay. That is the tool for them.
Try both for two weeks.
The two scripts run on the same page without conflict. Keep Amplitude doing what it does, and let GrainQL work next to it for two weeks.
- 1
Add the GrainQL tag next to Amplitude.
Paste one script tag in the head, or add it in GTM. It takes about two minutes. Leave your Amplitude SDK, events and experiments as they are.
- 2
Ask both tools the same question.
Pick one real drop from the last month. Ask Neo, then ask Amplitude's agent. Note how long each took and how much setup each answer needed.
- 3
Decide by who did the work.
If your team got answers from GrainQL without an analyst, keep it. If nobody missed it and Amplitude covered you, cancel the trial and stay.
Get the side-by-side test plan.
One page on running GrainQL next to Amplitude: what to install, what to compare, how to decide.
Questions.
Yes. The GrainQL script runs next to the Amplitude SDK on the same page. You can keep Amplitude for experiments and cohorts and use GrainQL to find why conversions dropped.
Ask Neo where your site loses money.
