Heap alternatives: 5 open-source picks
These 5 Heap alternatives replace it for $0, led by Umami, PostHog and OpenPanel. All 5 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
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
facts verified 2026-08-10
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

how to choose a Heap alternative
Easiest to get running
Plausible — a one-click install, no server to maintain.
Most proven
Umami, with 38,073 GitHub stars — the largest community of the 5, which usually means more answers when something breaks.
Works on your phone
PostHog has a mobile app on iOS and Android.
Needs real ops to self-host
OpenPanel is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Heap
- automatic capture engine, identity graph, data science, governance, and enterprise operations
- identity stitching
- session replay
- warehouse connectors
- high-volume global ingestion and support
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Heap
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.
