PostHog
Pros
- + Free tier resets monthly and covers real work: 1M events, 5K recordings, 1M flag requests and 100K exceptions per month, with every feature available and no credit card
- + Funnel-to-replay-to-error-trace in one timeline replaced a three-tool debugging loop I used to run across separate user IDs
- + Self-hosting under MIT keeps event data inside your own infrastructure — the practical answer I recommend for regulated teams
- + No seat-based pricing at all; adding engineers, PMs and analysts to my projects never changed the bill
- + Billing limits are hard caps you set yourself, so a runaway autocapture config stops at your ceiling instead of at a surprise invoice
Cons
- - Session replay, not analytics, became the largest cost line in my test project once traffic passed the 5K free recordings
- - The interface packs nine-plus products into one navigation; new users I onboarded needed a full day before finding the right tool consistently
- - Self-hosting is a genuine ops burden (ClickHouse, Kafka, Postgres) and the self-hosted build lacks SAML SSO and granular permissions
- - Identified events cost nearly 4x anonymous events in the first paid band, so user-identification choices move the bill more than event volume does
- - Past a billing limit PostHog drops data until the next period — cost control comes at the price of visibility
Eleos Health
Pros
- + EHR-agnostic browser-extension deployment means no API or HL7 integration project — in my walkthrough it sat on top of a web-based EHR with no custom build.
- + Compliance engine reviews 100% of notes against seven named checks (Uniqueness through Golden Thread) instead of the 5-10% sample rate manual QA teams manage.
- + Speech handling covers 150+ languages including mixed-language speech like Spanglish, which matches the bilingual caseloads common in community mental health.
- + 2026 agent additions (Eligibility Intelligence, Coding Agent) target revenue leakage upstream; early customers report 25% fewer Medicaid clients misclassified as uninsured.
- + Deep compliance posture: SOC 2, HITRUST, ISO 27001/27799/42001 certifications, HIPAA and FERPA compliance.
Cons
- - No self-serve signup, public pricing or free trial; market rates I found run $129/user/month (Documentation) and $119/user/month (Compliance) with $50k annual minimums (Indiana Council purchasing doc, May 2025).
- - Implementation fees in the $10,000-$30,000+ range make the product unreachable for small practices and solo clinicians.
- - Headline outcome stats (70% less admin time, 20% less turnover) are vendor-reported with no independent study I could find.
- - Vendor copy contradicts itself: the compliance page heads a '7-Point Compliance Analysis' but the body claims a 'six-point' review.
- - Group therapy documentation only shipped in September 2025, so that mode is much newer than the individual-session flow.
