Key differences
| Criterion | Amplitude | PostHog |
|---|---|---|
| Primary strength | Governed product intelligence | Engineering and product operations breadth |
| Core analytics | Stronger governance Mature self-service analysis | Flexible analysis with HogQL and developer context |
| B2B accounts | Paid Accounts package | Paid Group Analytics add-on with documented limitations |
| Replay | Web plus beta native mobile replay | Web and supported mobile replay linked to developer context |
| Experiments and flags | Feature/Web Experiment and feature management | Experiments commonly use metered flags; external exposure supported |
| Guides and surveys | Both native | Surveys native; no current first-class guide product verified |
| Developer operations | Replay error analytics; no general logs product | Stronger Errors, logs, AI observability, workflows |
| Deployment | Managed platform | Managed cloud plus limited unsupported hobbyist OSS edition |
| Billing | Platform event volume plus packages | Separate product usage meters |
Both cover the core workflows; their centres of gravity differ
Amplitude
Governed product intelligence
Shared across both
PostHog
Engineering and product operations
Analytics team owns the model Engineering owns the instrumentation
Overlap in a capability list does not mean equal depth. Consolidation decisions should distinguish mature, plan-dependent, early-access, legacy and absent.
Decision by scenario
| Scenario | Start with | Why | Important limitation |
|---|---|---|---|
| Product/data-led analytics program | Amplitude | Governed metrics and broad analytical workflows | Requires instrumentation and administration ownership |
| Engineering-led product platform | PostHog | Release controls, replay, errors, data, and automation connect | Module breadth and maturity vary |
| Experiment-heavy team | Evaluate both | Both connect analytics, flags, and experiments | Compare exposure logic and pricing meters |
| B2B account analysis | Evaluate both | Both offer paid group/account models | Capture active account context at event time |
| Developer diagnostics | PostHog | First-class errors, logs, and observability | Not every newer module has equal maturity |
| Native guides and engagement | Amplitude | Mature Guides and Surveys product family | Expanded packaging may apply |
| Supported full self-hosting | Neither | PostHog OSS is officially limited and unsupported | Choose a supported self-hostable category if required |
Analytics, B2B accounts, and session replay
Amplitude usually offers the stronger governed analytical environment. PostHog connects competent analysis more directly to engineering and release evidence.
| Capability | Amplitude | PostHog | Decision |
|---|---|---|---|
| Funnels, retention, cohorts | Mature self-service analysis with governed definitions | Flexible reports integrated with flags, replay, and HogQL | Amplitude for governance; PostHog for developer context |
| Metrics | Metrics Library, official definitions, plans, and schemas | Flexible schema and SQL-like analysis; authority is more team-designed | Amplitude if standardization is central |
| Account model | Accounts package and account reporting | Group Analytics for companies, workspaces, or projects | Paid add-on/package |
| Replay | Linked to events and analysis; native mobile replay is beta | Linked to persons, flags, experiments, exceptions, and developer context | PostHog for diagnostics; pilot mobile parity |
| Privacy | Managed controls and enterprise governance | Replay privacy controls plus cloud/self-host decisions | Review capture defaults and data minimization |
| Warehouse | Connections, imports, exports, and Activation; Warehouse Native is legacy | Managed Warehouse and source connections | Validate the current architecture |
For B2B SaaS, add the active company or workspace key to relevant events. A mutable user profile cannot reliably reconstruct historical company context. Group support also does not calculate adoption breadth, user penetration, or usage concentration automatically. See account vs user adoption.

Filled segments show documented emphasis, not a score. Hatched segments are plan-dependent, add-on or early stage. Verify the exact packaging in a pilot.
Engineering, data, and deployment
PostHog has the clearer advantage when the purchase is also about developer operations.
| Capability | Amplitude | PostHog | Buyer implication |
|---|---|---|---|
| Error tracking | Replay Error Analytics, not a general issue product | Issues, traces, source maps, breadcrumbs, ownership, and alerts | PostHog stronger |
| Logs | No first-class general log store documented | OpenTelemetry-oriented search, patterns, and alerts | PostHog may replace a narrow log workflow, not every observability tool |
| AI observability | Early-access Agent Analytics connects traces to outcomes | Prompts, tokens, cost, latency, tools, and traces | Compare maturity and cost |
| Automation | Activation, monitoring, alerts, and analytical agents | Workflows with triggers, conditions, delays, branches, and actions | PostHog for engineering-owned automation |
| Self-hosting | No supported full platform | OSS edition is hobbyist-oriented, limited-parity, single-machine, and unsupported | Do not treat OSS as cloud-equivalent enterprise deployment |

Detailed pricing notes
At verification, PostHog published separate allowances and rates for flags, exceptions, logs, warehouse rows, pipelines, surveys, AI-observability events, workflows, and Group Analytics. Amplitude’s effective cost depended on event volume, Accounts, experiments, replay, Guides and Surveys, Activation, governance, and enterprise terms. Treat all amounts as a dated snapshot and model expected and stress-case usage.
The matching one-decimal rating does not choose a winner. Product scope, customer mix, implementation maturity, and the relevance of each review matter more.
Which should you choose?
| Choice | Choose it when | Implementation caveat |
|---|---|---|
| Amplitude | Governed product insight and cross-functional product operations are primary | Budget for event design, administration, and package ownership |
| PostHog | Engineering wants to connect analytics, release controls, diagnostics, data, and automation | Set boundaries around modules, meters, and maturity |
| Use both temporarily | You are migrating or testing a separated architecture | Keep one metric and identity owner |
Where Hymetry fits
Hymetry is narrower account-centric product intelligence for B2B SaaS. It does not replace Amplitude’s analytical suite or PostHog’s engineering platform.
| Decision | Consider Hymetry when | Choose Amplitude or PostHog when | Hymetry’s limitations |
|---|---|---|---|
| Primary job | Company-level usage is the default view | Broad analytics, experiments, flags, or developer operations are primary | Less analytical and engineering breadth |
| B2B workflow | Companies, Users, Visits, adoption breadth, and concentration belong together | You can build account analysis from general group primitives | Smaller ecosystem and fewer integrations |
| Evidence | Customer teams inspect Visits behind account signals | You need deeper general replay or diagnostics | No comparable independent review base |

Frequently asked questions
Which has stronger product analytics?
Amplitude generally has stronger governed self-service analysis and enterprise metric workflows. PostHog provides flexible funnels, retention, paths, cohorts, and HogQL while connecting them closely to flags, replay, errors, and engineering context.
Which is better for B2B accounts?
Both require paid packaging and reliable group keys. Amplitude’s Accounts package fits its broader analytics suite; PostHog’s Group Analytics supports companies or workspaces but has documented limitations across some analyses. Validate event-time account context.
Which has stronger session replay?
Amplitude connects replay to its analytics workflow, with native mobile replay still beta at verification. PostHog connects replay to persons, flags, experiments, exceptions, and developer diagnostics. Verify mobile parity, masking, retention, and pricing.
Can PostHog be self-hosted?
An open-source edition exists, but official guidance describes it as hobbyist-oriented, single-machine, limited-parity, and unsupported. Do not treat it as equivalent to PostHog Cloud or as a supported enterprise deployment without accepting the operating burden.
Which has the better free plan?
Amplitude listed 2 million monthly analytics events and 10,000 replays. PostHog listed 1 million analytics events plus separate allowances for replay, flags, errors, logs, warehouse, surveys, and other products. The better offer depends on which meters your workload uses.
Can Amplitude replace PostHog Error Tracking and Logs?
No direct equivalent was verified. Amplitude Replay Error Analytics helps investigate replay errors, while PostHog provides first-class Error Tracking and Logs. A buyer should still compare either with specialist observability tools for production-critical needs.
