Does anyone know what the context for this is? Because https://github.com/PostHog/posthog exists as well

The sheer number of files in the root of that project is making my OCD itch like crazy. That would drive me insane.

Very interesting but why would they do this?

The AGENTS.md is interesting, apparently the primary most important principle is, "Avoid em-dashes like the plague". That's an odd request. I always use my own voice for certain things, such as posting to hacker news, or writing my thoughts on a proposal. But for other things such as writing up a bugfix, if I'm getting an AI to write it, I'd rather not hide the fact I've done so. In fact I usually go out my way to mark it as AI written, to give a heads up to any human reader so they don't waste their time if they don't want to read it. edit: I'm not sure why my comment is attracting downvotes, perhaps it's being interpreted as anti-AI. I'm not against AI writing, but there are contexts where people would like to know whether something is AI written or not. I would rather it was well identified than hidden, so people can make their own judgement whether to gain insight into a human writing or whether it's just process they can skim or feed through their own agent. "Avoid em-dashes" just seems like a crude attempt to avoid AI writing coming across as such.

Last time I checked, Posthog self hosted was basically unusable. They have a hobby deployment script which just pulls the latest build from master which varies from “somewhat works” to “completely broken”

Congratulations!

It's hard for me to express how much I dislike their marketing website. Sometimes when you have a "cool idea" you should sit with it a moment and then pull back.

I have a weird memory of PostHog. I remember applying sometime ago, not really knowing what they did. They then spammed me with marketing mail, now they're open-sourced and had received a (supposedly marketing) job posting? Granted in this entire history I had no idea what their product was. Seems flakey, but I haven't used it.

in the youtube video, by 'product' do they mean 'website' ? I feel I'm missing some basics as to what this can do for me or what problem it solves. edit so it's like google analytics .

um... we've had this posthog-foss repo for years now. No idea why it made front page. This is not news. Source: I was there To clarify: PostHog has been MIT licensed since day 1, with the exception of the `ee/` folder. This `posthog-foss` repo is a mirror of the main `posthog` repo with the `ee/` folder removed. We've had it for ages.

Looks like they created mess with AI and then open sourced it. I remembered I had to shift from them to metabase because they closed sourced their deployments docker/kubernetes I guess it was 3 years back. But now AI screwed them over so they come with their own open-source spaghetti.

I just recently switched to posthog self hosted and it works fine

I used to like their product but now they too many modules and knobs that I find it difficult to understand and navigate. I think is a bit of product slopification.

Needs (2020) I guess?

PostHog has always been open source. Please update title accordingly.

I recently had to turn off posthog on my app, it was collecting so much information that wasn't needed that it was making my app unusably slow. I'm sure i'm missing some knob, but the fact that after an hour long claude code session i couldn't figure out how to fix it means posthog has gotten too fiddly.

I'm surprised - weren't they always OSS?

raffraffraff

Lol, is github down again?

Open sourced ?! I believe it was open source from day one.

What the actual fuck is going on with web development nowadays? Look at the sheer number of ancillary files in this repo: .agents .claude .config .cursor .dagster_home .depot .flox .github .husky .idea .interface-design .pi .posthog-code .run .semgrep .stamphog .vscode .zed agent-os bin cli common devenv docker docs frontend funnel-udf livestream nodejs packages/quill patches playwright posthog products proto rust services share terraform tools .cursorignore .cursorrules .dockerignore .editorconfig .env.development .env.example .env.local.example .env.services .envrc .git-blame-ignore-revs .gitattributes .gitignore .kearc .mcp.json .nvmrc .oxfmtrc.json .oxlintrc.json .stylelintignore .stylelintrc.js .test_durations .test_quarantine.json .watchmanconfig .worktreeinclude .worktreelink AGENTS.md AI_POLICY.md CHANGELOG.md CLAUDE.md CONTRIBUTING.md Dockerfile Dockerfile.llm-analytics Dockerfile.ml-mirror-image-scrub Dockerfile.node Dockerfile.playwright Dockerfile.recording-rasterizer Dockerfile.sandbox LICENSE README.md conftest.py dagster_cloud.yaml depot.json dist-workspace.toml docker-compose.base.yml docker-compose.dev-full.yml docker-compose.dev.yml docker-compose.hobby.yml docker-compose.multinode-clickhouse.yml docker-compose.playwright.yml docker-compose.profiles.yml docker-compose.sandbox.yml greptile.json hogli.yaml manage.py otel-collector-config.dev.yaml package.json pnpm-lock.yaml pnpm-workspace.yaml postcss.config.js posthog.json pyproject.toml pytest.ini tach.toml tsconfig.dev.json tsconfig.json tsconfig.kea-typegen.json turbo.json unit.json.tpl uv.lock What percentage of those files are actually directly related to the source code of the software? 1%? How can anyone in their right mind look at this kind of setup and feel good about it?
