PostHog Free Plan (universal monthly free tier) — Observability & Product Analytics high confidence
Every PostHog product ships with a monthly free allowance that resets each month; same allowance whether or not a card is on file; usage stops at the limit so you cannot be overcharged. Exact free limits (US Cloud, current as of 2026-10-22): Product Analytics 1,000,000 events; Session Replay 5,000 web + 2,500 mobile recordings; Feature Flags 1,000,000 requests (Experiments billed with feature flags); Error Tracking 100,000 exceptions; Surveys 1,500 responses; Data Warehouse Sources 1,000,000 rows + free historical syncs; Destinations 10,000 trigger events + 1M rows; AI Observability (ex-LLM Analytics) 100,000 events; PostHog AI 500 credits (~$5); Logs 10 GB ingested; Replay Vision 2,500 credits (~$25); PostHog Desktop 2,000 credits (~$20); Workflows 10,000 messages/channel; Inbox Beta 3 PRs; Emails 10,000. Free plan = 1 project, 1-year data retention (session recordings kept ~1 month), unlimited team members, community support, SSO (Google/GitHub/GitLab), API access.
Eligibility
Open to everyone — students and startups included. No .edu email required, no credit card required, no region restriction (US Cloud default; EU Cloud available). Not a trial: it is a perpetual free tier that 'renews every month... forever.'
How to claim
Sign up at app.posthog.com or posthog.com/pricing ('Get started – free'); install SDK / add tracking code. Free allowance auto-applies every month, no application or card step needed.
Expiry
Perpetual; the free allowance renews every month. No expiry or annual review on the base free tier.
Gotchas
It is explicitly 'not a trial, no credit card' — a true perpetual free tier, not a 14-day trial. Free plan is capped at 1 project; adding a card (Pay-as-you-go) unlocks 6 projects and 7-year retention, not a higher free tier. Beyond the free caps you pay usage-based, and you can set per-product billing limits to prevent surprise bills. Logs custom retention beyond the free allowance is charged ($0.05/GB-month).
Error Tracking free tier (Monitoring front) high confidence
Generous free tier of 100,000 exceptions/month, GA (out of beta April 2025). No credit card required; you can set billing limits. After the free 100K: tiered pricing 100k–325k $0.000370/exception, 325k–10M $0.000140/exception, 10M+ $0.000115/exception. Bill is driven by ingested $exception events (suppression rules drop future matching exceptions pre-ingestion and are not billed).
Eligibility
Anyone on the PostHog free tier — students/startups, no .edu or card required.
How to claim
Included automatically in the free tier once error tracking SDK is enabled; no separate application.
Expiry
Perpetual monthly free allowance; renews each month.
Gotchas
Exception autocapture on by default can over-capture; you can trim captured types client-side. Merging/resolving/suppressing existing issues does not reduce the bill; suppression only saves on future matching events.
PostHog for Startups — $50,000 in free credits medium confidence
$50,000 in free PostHog credits for 12 months for early-stage teams (page headline: '$50K in credits for early-stage teams'). Official eligibility stated on the pricing page: company younger than 2 years and total funding raised under $5M. Credits are applied on top of/within a pay-as-you-go account so usage can far exceed the free tier.
Eligibility
Startup (not education): founded <2 years ago, <$5M total funding raised. No .edu requirement; aimed at VC/startup founders.
How to claim
Apply at posthog.com/startups ('Get started – free' → app.posthog.com/signup). The page's application/claim steps were not fully readable in this fetch; apply via the startups page. Note: the base free tier needs no card, but redeeming $50K of usage credits effectively puts you on a pay-as-you-go account (card requirement for that account not explicitly confirmed on the page).
Expiry
12-month credit window.
Gotchas
Credits are for 12 months (time-boxed), not perpetual. The eligibility caps (<2 yrs, <$5M raised) mean a more mature startup is not eligible. Do not confuse with the separate Y Combinator offer below.
Y Combinator Startup Program — $50,000 free credits/yr, renewable high confidence
Y Combinator-backed companies get $50,000 in free PostHog credits per year, renewable while the company's total funding raised stays under $25M (separate, YC-specific program listed on the pricing page).
Eligibility
Y Combinator companies (or a company that raised via YC); total raised must stay < $25M to keep the renewal. No .edu.
How to claim
Applied through PostHog's YC/startup program (posthog.com/startups and pricing page); YC-backed teams claim the annual $50K.
Expiry
Renews annually while raised < $25M.
Gotchas
Renewal is gated on the $25M raised ceiling — once raised funding exceeds $25M the renewable credits stop. Distinct from the general <2yr/<$5M startup program.
Non-profit discount (adjacent to student/startup audience) high confidence
Registered non-profits receive 15% off purchases under $25k; an additional 5% stacks on top of standard volume discounts in the $25k–$100k range. This is a discount (not a free tier), but is one of PostHog's stated offers alongside the startup discounts.
Eligibility
Registered non-profit organization (no .edu, no startup age cap).
How to claim
Noted on the pricing page; apply the discount when setting up a paid account.
Expiry
Ongoing discount; no expiry stated.
Gotchas
It is a percentage discount on spend, not free usage; the free tier (finding 1) already covers most non-profit baseline needs at $0.
Education / student license — no dedicated program found medium confidence
No dedicated PostHog education, student, or .edu license/program exists in the official site. A direct fetch of posthog.com/education returns 404 (no page), and the FAQ/pricing pages do not list a student-only offer. Effectively, the 'education' front is served by the universal free tier: students can use all products free (1M events, 5K replays, 100K exceptions, 10GB logs, etc.) with NO .edu email and NO credit card, so classroom/student projects are covered at $0.
Eligibility
No .edu email required, no institutional agreement, no special license — the free tier is open to any student. (No evidence of a distinct education-specific benefit.)
How to claim
Same as the free tier: sign up at app.posthog.com; no separate education application exists to claim.
Expiry
n/a (no dedicated program; rides on the perpetual free tier).
Gotchas
Because there is no dedicated education program, there is no .edu-verified perk or extended data-retention for students; students get the same 1-project / 1-year-retention free tier as everyone else.
Uptime & CDN fronts — no dedicated PostHog product medium confidence
PostHog does not sell a standalone uptime-monitoring service or a CDN, so there is no free offer specifically in those two fronts. Its 'monitoring' coverage comes through the free tier's Observability stack: Error Tracking (100K exceptions free), Logs (10 GB free), Web Vitals / performance capture, and alerts. 'Monitoring' in the uptime-sense (ping/SLO uptime checks) and any CDN/edge delivery are out of scope of PostHog's product list (analytics, session replay, feature flags, experiments, error tracking, logs, surveys, workflows, AI observability, data warehouse, destinations, inbox, PostHog AI).
Eligibility
n/a — no uptime or CDN product to claim.
How to claim
n/a. For uptime/CDN you would need a different vendor; PostHog's free value is in error tracking + logs + analytics, not uptime pings or a content/edge network.
Expiry
n/a.
Gotchas
Don't list a 'free uptime monitoring' or 'free CDN' as a PostHog offer — none exists. Web-vitals/performance data inside analytics is the closest monitoring feature, and it is covered under the 1M-event free analytics allowance.
2025-2026 changes that matter for the 'free offer' claims: (1) In 2025 PostHog raised several free-tier limits — a third-party (metacto, updated 2025-10-24) reports Surveys free allowance increased from 250 → 1,500 responses/month, and Data Pipelines free quota changed to 10K events + 1M rows (previously 1M events). These 'after' values match today's official pricing page (1,500 surveys; 10K destination trigger events + 1M rows); the 'before' values are third-party (medium confidence). (2) A new AI/LLM product launched in 2025 with 100K free events/month, initially named 'LLM Analytics' (per the 2025 metacto article) and now shown on the 2026 pricing page as 'AI Observability' — i.e., the 100K free-events figure is a 2025 addition / rebrand, not part of the original 2024 free tier. (3) Context from 2024: PostHog cut session-replay and analytics-event prices, and in 2025 cut data-pipeline and survey prices — so the free tier has generally been expanding, not shrinking. (4) Error Tracking went GA (out of beta) around April 2025 with its 100K free-exceptions tier; before that it was a beta. (5) No student/education program or startup/YC program was sunset in 2025-2026: the $50K startup program (<2yr, <$5M), the YC $50K/yr program (<$25M raised), and the 15% non-profit discount all remain live on the current pricing page. (6) Tangential: 2025 self-hosting guidance changed (support for new Kubernetes/Helm installs ended) — affects self-hosted users, not the cloud free tier. Net: every 'known so far' claim (free error tracking, session replay, logs, 1M events, no credit card) is CONFIRMED and current; nothing in the free-offer set was removed, only some limits were raised.
