Heap alternatives: 4 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Small, explicit event analytics with funnels and retention, hosted on infrastructure you control.
licenseMIT
runsyour machine or their cloud
installCreate an Umami Cloud account or deploy the Node application with Docker Compose and PostgreSQL
dataA self-hosted deployment stores analytics and account data in PostgreSQL; Umami Cloud stores it in Umami's managed service
the catch vs HeapIt is lightweight explicit-event analytics with no equivalent to Heap's automatic capture and retroactive history.
setupNone for hosted signup; self-hosting requires Docker or Node hosting and a PostgreSQL database

Explicit events, funnels and retention without being forced to autocapture the rest of a person's life.
licenseMIT
runsyour machine or their cloud
installCreate a PostHog Cloud project or use the hobby self-host script on a Linux server
dataThe self-hosted stack splits analytics, transactions, queues and recordings across ClickHouse, PostgreSQL, Kafka, Redis and object storage; cloud data lives in PostHog's managed regions
the catch vs HeapIt can autocapture, but its retroactive data engine and schema-governance workflow are less polished than Heap's.
setupNone for hosted signup; self-hosting is an unsupported, resource-heavy multi-service stack requiring serious operations work

Event analytics and user timelines without automatic snooping; ClickHouse administration is the trade.
licenseAGPL-3.0
runsyour machine or their cloud
installCreate a hosted account or run the self-host installer and Docker stack
dataA self-hosted deployment uses PostgreSQL for account data, ClickHouse for event data and Redis for cache and queues; hosted data lives in OpenPanel's service
the catch vs HeapIt depends on explicit events and does not provide Heap's automatic capture history for retroactive questions.
setupNone for the hosted free tier; self-hosting requires Docker, DNS or a reverse proxy and several persistent services
facts verified 2026-08-10
A transparent event stream with funnels and retention, free up to a million monthly events.
licenseproprietary, free
runstheir cloud
installCreate a hosted project and add a Mixpanel SDK or tracking snippet
dataStructured events and user profiles are stored in Mixpanel's managed cloud
the catch vs HeapIt requires deliberate event instrumentation and cannot recreate Heap's retroactive analysis of automatically captured interactions.
setupThe software installs cleanly, but meaningful use starts with designing an event taxonomy and instrumenting the product

People still pay for Heap because teams pay because analytics must keep collecting and remain trustworthy while the product changes underneath it. The recurring cost buys event schemas, bot filtering, identity, late data, retention, query cost, privacy, backups, and always-on ingestion, not just the visible interface.
Is there a free alternative to Heap?
Yes: Umami, PostHog, OpenPanel and 1 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Heap?
Our verdict is NO TANTO. A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Heap, instrument explicit first-party events and avoid automatic capture of unrelated user behavior. The hard boundary is automatic capture engine, identity graph, data science, governance, and enterprise operations, plus data pipeline reliability and analytical depth. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/heap.
