6 free alternatives to Amplitude

Apstal's free plan gives you 100K events per month, session replays with 24-hour retention, 15 analytics views, one website, and access to its SQL AI Agent plus MCP for plain-English questions. It also includes funnels, retention, path analysis, Core Web Vitals monitoring, JavaScript error monitoring, and adblock-resistant tracking. Compared with Amplitude, it is strongest on event allowance per month and on built-in monitoring. It falls short on the breadth of included suite features and the larger product-analytics ecosystem. Switch here if you want a web analytics stack with a higher event cap and conversational querying, and you can live with a narrower footprint.

• Beats Amplitude: Higher monthly event allowance.
• Falls short: Narrower free-plan ecosystem and fewer included suite features.
• Who should switch: Switch if your priority is a higher event cap plus basic replay and analytics for one website.

PostHog's free tier includes 1 project, 1-year data retention, unlimited team members, community support, 1M product analytics events per month, 5,000 session replay recordings per month, 1M feature flag requests per month, 1,500 survey responses, 1M managed warehouse rows, free historical warehouse syncs, 100K error tracking exceptions, 2,000 AI credits, 100K LLM analytics events, and logs and workflow quotas. It is broad rather than narrow, covering analytics, replay, flags, surveys, data warehousing, error tracking, and automation in one place. It beats Amplitude on scope across engineering and data workflows. It falls short on pure event headroom if you want more than a million events without moving up. Switch if you want the broadest free product-operations bundle.

• Beats Amplitude: Broader free coverage across product, data, error tracking, and workflows.
• Falls short: Lower event headroom than Amplitude's 2M events.
• Who should switch: Switch if you want one free platform for analytics plus flags, surveys, errors, and warehouse syncs.

Mixpanel's free forever plan includes up to 1M monthly events, up to 5 saved reports per seat, 10K monthly session replays, and unlimited seats. That makes it a straightforward analytics option for teams that mainly need event tracking, reporting, and replay without paying upfront. It beats Amplitude on report simplicity for small teams because the saved-report limit is explicit and the seat count is unlimited, which can suit cross-functional use. It falls short on event capacity and on the wider set of included product features Amplitude offers, such as experimentation and AI feedback. Switch if you want a lighter analytics setup with unlimited seats and a familiar event-plus-replay model.

• Beats Amplitude: Unlimited seats on the free plan.
• Falls short: Lower monthly event cap than Amplitude.
• Who should switch: Switch if you need many collaborators but can fit inside a smaller event allowance.

Statsig's Developer free tier includes 2 million events per month, unlimited flag and config checks, 50,000 session replays per month, A/B tests and experimentation, feature flags and config management, product and web analytics, 1-year analytics retention, session replays, and unlimited seats. It is especially free in the areas Amplitude users often care about most, since the replay quota is much larger and the flags and experiment tooling are baked in. It falls short if your use case is centered on broader research feedback or a more all-in-one analytics suite outside release management. Switch if you want analytics tied closely to feature delivery and experimentation.

• Beats Amplitude: Much higher free session replay allowance.
• Falls short: Less oriented to research feedback and broader all-in-one analytics than Amplitude.
• Who should switch: Switch if your team lives in flags, experiments, and release measurement.

Heap's free plan includes core analytics charts, unlimited enrichment sources, Guides integrations, 6 months of data history, SSO, and up to 10K monthly sessions. It is useful for teams that want automatic capture plus governance-adjacent basics without manual tagging. Heap beats Amplitude on data history when you compare the free-plan shape, since it gives a defined retention window and SSO in the free tier. It falls short on monthly volume, because 10K sessions is far tighter than Amplitude's 10K MTUs and 2M events. Switch if your priority is lightweight product analytics with enrichment and SSO, not traffic scale.

• Beats Amplitude: Includes SSO and unlimited enrichment sources on the free plan.
• Falls short: Much tighter usage ceiling on monthly sessions than Amplitude's event allowance.
• Who should switch: Switch if your team values automatic capture and simple governance more than volume.

FullstoryFree includes 30,000 monthly sessions, 12 months of analytics retention, Session Replay, basic analytics, debugging tools, and up to 10 users. That makes it a clean choice for teams that care most about watching user behavior and troubleshooting issues. It beats Amplitude on included session volume and on retention depth in the free plan, while staying focused on replay-driven analysis. It falls short on product analytics breadth and on the larger feature mix that Amplitude bundles, including experimentation, feature flags, and AI feedback. Switch if you mainly want replay and debugging with enough history to investigate problems over time.

• Beats Amplitude: More free monthly sessions and longer analytics retention.
• Falls short: Less breadth across experimentation, flags, and AI feedback.
• Who should switch: Switch if session replay and debugging are the main reason you are shopping.
