If you're building a product, at some point you need to know what people actually do inside it: which features get used, where they drop off, whether a change moved the needle. That's "product analytics" — and for years the default answer was Mixpanel or Amplitude. Both are solid, but they're also expensive at scale, heavy to set up, and not always a great fit if you care about data privacy or just want something simpler. Below are six tools people are actually switching to in 2026, each with a different angle: open-source self-hosting, GDPR-first design, all-in-one feature flags, or just fewer dashboards to babysit.
1. Statsig — for teams who want experiments, not just dashboards
Statsig is less "analytics tool" and more "answer whether the feature actually worked" tool. It bundles feature flags, A/B testing, product analytics and session replay into one system, so instead of shipping a feature and separately checking a dashboard, you can see the causal impact of that specific rollout tied to the experiment that shipped it.
Pricing: free up to 2M events/month, then $150/month for 5M events, with custom enterprise pricing above that.
Good for: product managers and engineers who want experimentation and analytics in the same place instead of stitching together a flagging tool and a separate analytics tool.
Watch out for: it's younger and less enterprise-battle-tested than LaunchDarkly, and its core repos are mostly closed-source, so there's a thinner trust signal if you specifically want to audit the code.
2. OpenPanel — the open-source, self-hostable option
OpenPanel is an open-source Mixpanel/PostHog alternative that you can self-host for free with no event cap, under an AGPL-3.0 license. It covers funnels, cohorts, session replay and revenue tracking, and even ships an MCP server so an AI assistant can query your analytics directly.
Pricing: self-hosted is free with unlimited events; the hosted cloud version starts at $20/month with pay-per-event beyond the included allotment, and a 30-day trial.
Good for: startups that want full data ownership and don't mind running their own infrastructure.
Watch out for: AGPL-3.0 has copyleft implications if you're embedding it into a product you sell, and it's a younger project than the incumbents it's replacing.
3. Grain Analytics — GDPR-first with an AI analyst built in
Grain Analytics is hosted in the EU, doesn't use third-party cookies, and includes an AI analyst ("Kai") that flags conversion drop-offs automatically — useful if you don't have a data analyst on staff to write the SQL yourself. It covers both web and mobile with session replay and heatmaps.
Pricing: 14-day free trial, no card required; paid plans start at $29/month across three tiers, with the AI analyst gated by plan.
Good for: SaaS teams in or selling into the EU who need GDPR compliance handled by default, without a dedicated data team.
Watch out for: no permanent free tier, and it costs more than the open-source options on this list — the EU-compliance positioning also matters less if most of your users are elsewhere.
4. Nexly — no feature gates, and it separates bot traffic from real users
Nexly gives every plan the full feature set (no "upgrade to unlock cohorts" games) and specifically separates human, bot, and AI-crawler traffic in its reporting — a real problem now that a meaningful chunk of web traffic is scrapers and agents, not people. It supports 9+ platforms including React, Next.js, Flutter, Swift and Kotlin.
Pricing: free tier with 10k events/month; paid tiers run $45/year (Hobby) up to $995/year (Business, 2M events/month) — billing is annual-only, no monthly option at the lower tiers.
Good for: teams with a mixed tech stack who want one tracking setup across web and mobile without hitting artificial feature walls.
Watch out for: the annual-only billing is a real commitment if you're not sure yet, and event caps can bite on the lower tiers if you get a traffic spike.
5. Vemetric — zero cookies, no consent banner, product + web analytics combined
Vemetric collects no personal data and needs no cookie banner by default, while still covering both web analytics (the Plausible/Fathom use case) and product analytics (funnels, user journeys) in one tool. It's open source (AGPLv3) so the privacy claims are actually checkable, and the paid tier starts at just $5/month.
Pricing: free tier with 2,500+ events/month, 2 projects, 1-month data retention; Professional at $5/month with unlimited projects/seats and 5-year retention.
Good for: indie SaaS builders who want to skip the cookie-consent conversation entirely and get both web and product analytics without paying Amplitude prices.
Watch out for: the free tier only retains data for a month, the integration ecosystem is thinner than Mixpanel/Amplitude, and it's effectively a single-founder project with under 300 GitHub stars — early, not battle-tested.
6. Propane — less "analytics dashboard," more "one source of truth about a customer"
Propane takes a different angle: instead of another set of charts, it pulls signals from 300+ tools your team already uses (support tickets, calls, billing, feedback) into one live customer record, and can feed that context directly into AI coding agents. It's SOC 2 Type II and GDPR compliant.
Pricing: quote-based, unlimited users per contract — no published number, requires a demo; a free trial is available.
Good for: product, design and product-ops teams at SaaS companies who are tired of decisions being made off whichever tool someone happened to check that day.
Watch out for: no public pricing means a sales conversation before you know the cost, it's a young and thinly-funded startup (~€1M raised) competing with well-established players, and the real value depends heavily on how many of your existing tools it can actually plug into.
Quick comparison
| Tool | Best for | Starting price | Self-hostable |
|---|---|---|---|
| Statsig | Analytics tied to experiments/flags | Free up to 2M events, then $150/mo | No |
| OpenPanel | Full data ownership, open source | Free self-hosted / $20/mo cloud | Yes (AGPL-3.0) |
| Grain Analytics | GDPR-first with built-in AI analyst | $29/mo (14-day trial) | No |
| Nexly | No feature gates, bot-traffic separation | Free / $45/yr | No |
| Vemetric | Zero-cookie web + product analytics | Free / $5/mo | Yes (AGPLv3) |
| Propane | Unified customer record across tools | Quote-based | No |
None of these are drop-in Amplitude replacements with identical feature parity — that's the honest trade-off of picking a smaller, newer tool. What you get instead is lower cost, no vendor lock-in with self-hosting, or a genuine privacy story you can put in front of EU customers without lawyers getting nervous. If you're pre-product-market-fit, start with Vemetric or OpenPanel's free tiers before paying for anything. If you're already running experiments and need the analytics tied directly to them, Statsig is the more direct fit.
