UserProof

Amplitude alternatives for founders who build with a coding agent

Updated . By Ryan Doyle, founder of UserProof, a session replay tool for coding agents.

Amplitude's Free plan gives 2M events and 10,000 replays a month, so founders rarely leave over price. If you build with a coding agent and want one fix with the file and line, UserProof is the pick, free for 5,000 visits. PostHog fits engineers who want one platform. Amplitude still wins on experiments.

One number only this page shows: we have read Amplitude's pricing page every morning since October 23, 2026. On all 14 reads through November 5 the only dollar figures on it were $0 and the $10M funding line of its startup scholarship. Above the free tier, no paid price is printed; the Plus plan points to an estimator and Growth and Enterprise to sales.

Cost at real volumes

Replays only, because that is the part most founders compare. Amplitude and Mixpanel also bill on events, so a busy product can pay for events first.

Reasons to switch from Amplitude

You don't want to plan events before you get an answer

Amplitude's model is events and a tracking plan: its MCP server even manages taxonomy and tracking-plan branches. That pays off for a product team with a data owner. A founder with one site and a coding agent can skip it. UserProof needs one script tag and a goal.

You want a change, and your agent to make it

Amplitude's MCP lets an agent read charts, query replays and build a ranked friction map. You still decide what to change. UserProof returns the one fix with the file and line, then compares the goal before and after you ship.

You want to see the price before you talk to anyone

Growth and Enterprise are “Contact sales”, and SSO starts at Growth. UserProof's three prices are on one page and have not moved since October 19, 2026.

Replays past 10,000 a month

Free and Plus stop at 10,000 replays and Growth at 20,000. More means an add-on priced as a percentage of the plan. UserProof Pro covers 50,000 for $29.

Where Amplitude still wins

NeedWhy Amplitude fits better
The biggest free tier here2M events and 10,000 replays a month, with unlimited seats. UserProof Free stops at 5,000 visits.
Experiments and feature flagsFeature flags are unlimited on every plan. Experiments allow 1 active on Free and Plus, with results from Growth. UserProof has neither.
Behavioral analysisCohorts, retention, journeys and predictions. UserProof doesn't try to do this.
An agent that writes backIts MCP can create charts, dashboards, cohorts and flags. UserProof's tools read findings and verify fixes.
Heatmaps and mobile replayHeatmaps from Plus, and replay for web and mobile. UserProof has no heatmaps and records websites.
StartupsUnder $10M in funding and fewer than 20 employees earns one free year of Growth.

FAQ

What is the best free alternative to Amplitude?

For pure session watching, Microsoft Clarity: free with no paid tier. For analytics, PostHog gives 1M events and 5,000 recordings a month free. If your agent should get the fix, UserProof is free for 5,000 recorded visits.

How much does Amplitude cost?

Free is 2M events a month. Plus starts at $0 and scales with event volume through an estimator, and Growth and Enterprise are quoted by sales. The page printed no dollar price above $0 on 14 daily reads through November 5, 2026.

Does Amplitude have session replay?

Yes, on every plan: 10,000 replays a month on Free and Plus, 20,000 on Growth and 50,000 on Enterprise, each kept 1 month, with add-ons for more on Growth and Enterprise. It also surfaces rage clicks and dead clicks.

Does Amplitude work with Claude Code?

Yes. Amplitude runs a hosted MCP server at mcp.amplitude.com/mcp that signs in with OAuth and works with Claude Code, Cursor, Codex and others. Any existing Amplitude customer can use it.

Is PostHog better than Amplitude?

It depends on the team. PostHog prints every price and adds error tracking and more for engineers. Amplitude gives more free, 2M events against 1M, and goes deeper on behavioral analysis. Our compare page has the numbers.
