The short version

  • Each has a real cost: PostHog the free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts; Robot Framework the keyword abstraction hides control flow, so debugging a failing test means tracing through library keywords rather than reading a stack trace, and experienced developers frequently resist maintaining suites written this way.
  • They diverge on capability: PostHog covers Product analytics, Robot Framework covers Keyword-driven syntax.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier

Robot Framework

  • The keyword abstraction hides control flow, so debugging a failing test means tracing through library keywords rather than reading a stack trace, and experienced developers frequently resist maintaining suites written this way.
  • The syntax is space-separated and whitespace-sensitive, which produces confusing failures for newcomers and makes editor configuration a prerequisite rather than a convenience.
  • Parallel execution is not built in and requires Pabot or a CI-level split, so scaling a large suite to run in minutes is work the team has to design themselves.
  • Test quality depends entirely on library choice, and the older Selenium-based library behaves very differently from the Playwright-based Browser library, so advice found online often does not apply to the setup in front of you.
  • Editor and IDE support is thinner than for mainstream languages, with refactoring, find-usages and type checking across keywords all weaker than a code-first framework provides.
  • Foundation governance means no vendor is accountable for a fix, so a defect in a widely used library is resolved on community time unless you buy support from a consultancy.

Answered from the vendors’ own pages

PostHog: What does PostHog's free tier include per month?

PostHog free tier includes: 1M analytics events, 5K session replays, 1M feature flag requests, 100K error tracking exceptions, 1,500 survey responses, 1M data warehouse rows, 10K data pipeline events, 100K AI observability events, 500 PostHog AI credits, 10K workflow messages, and 10GB log ingestion.

Robot Framework: Do testers need to know Python?

Not to write tests, which are keyword calls. Somebody on the team needs Python to write new keywords and debug library behaviour.

PostHog: How much data retention does PostHog provide on paid plans?

PostHog free tier provides 1-year data retention. Pay-as-you-go plans offer 7-year data retention across all projects, enabling longer historical analysis. Source: https://posthog.com/pricing

Source
Robot Framework: Is it still a reasonable choice against Playwright or Cypress?

For web-only automation owned by developers, usually not. For suites spanning APIs, desktop, hardware and web, where non-programmers must read the tests, it still has no close equivalent.

PostHog: What percentage of PostHog users stay on the free tier?

PostHog states that 97% of companies use PostHog for free, indicating extensive free tier adoption. However, specific per-unit pricing rates for overages on paid plans are not published. Source: https://posthog.com/pricing

Source
Robot Framework: Who controls the project?

The Robot Framework Foundation, funded by member companies. There is no owning vendor, no paid tier and no entity able to relicense it unilaterally.

PostHog: When does PostHog provide priority support on paid plans?

PostHog provides email or Slack support for accounts exceeding $2,000/month on pay-as-you-go plans. Specific response times and support SLAs are not detailed on their pricing page. Source: https://posthog.com/pricing

Source
Robot Framework: How do I run tests in parallel?

With Pabot or by splitting suites across CI jobs. The core runner is sequential.
