I empathize that this is a sane choice for PostHog to make as a business. But - if you can't deploy and dogfood your changes, are you truly able to maintain a fork with customizations? And if you can't use your own changes, is the software open-source, or source-available?
Perhaps the punchline is that any scalable & performant web analytics platform must necessarily be a distributed system of ingestion and storage services, and that complexity is like oil and water with the classic "you should be able to swap out the dependencies on your systems with ones you fork" open-source ethos.
PostHog had an opportunity to break this trend, to innovate and invest in those automations they correctly said didn't exist - and I was cheering them on. I've been saddened to see them move in the opposite direction.
Agreed, I tried self-hosting it a couple of month ago and it was impossible. I spent the day on it but the setup process was broken because of a recent change which was made for their cloud offering. Managing both a codebase both adapted to a cloud deployment with a huge amount of users and to a self-hosted way small deployment is very hard and requires a lot of resources. It's hard to justify investing this much time and money in making it work well for a self-hosted setup, and it seems like they stopped doing so.
It's still great to make the code open, but it's not usable anymore for a self-hosted setup.
I think posthog is one of these businesses where the COSS model does not work well.
COSS works well when there is a large distribution advantage of being OSS. This could be bacuse a large portion of users (need to) self-host the solution. This is true for databases, people will always need to self-host dbs (e.g. as part of their docker compose in dev, etc...). These people are also hard core engineers that will 1) talk about the db and 2) contribute to the project. So an OSS db have a large network effects and distribution advantage.
Posthog had a distribution advantage from OSS in their beginnings -- their beachhead was the self-hosting oss community. Now, it does not add much value -- It's unlikely Github adds much for their distribution. So, it does not make sense for them to do much more than just maintain it lightly. In fact, they try to push you from self-hosting by having great free tiers and startup programs.
They want you to buy their hosted service, that's where the convenience is sold. If they give you a one liner script you can paste in or a docker compose that does everything from scratch they cannot sell their hosted services.
Would love for you to try Amplitude. We've put a lot of work into making sure the core is usable. We've also started to fix a lot of the most common complaints about our pricing.
They've been using AI to shove a lot of AI into their product and trying to force everyone to use AI. I really don't understand the why of any of it. The product was working great for what it needs to do. I don't need AI to make guesses about data for me and I especially do not want _yet another product_ trying to write features in my codebase (which is their latest push).
I remember around 2 years ago give or take, we used it at a company for A/B testing. The UI was sensible enough. But fast forward to a couple of weeks ago, I opened an account and I just could not understand what I saw. I remember it being pretty good, too bad the UI got crappified with AI.
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.
If you are on react/next.js, defer the client side initialization until after your app has painted. PostHog (especially with their session recording feature) likes to initialize a little before the rest of your app loads through either their context provider or instrumentation.ts (if you are on next.js). It's generally insignificant except if you are building a B2C web app where the extra 100ms makes a difference in retention.
On the server side, queue all analytics call and run them after the main request completes (on next.js it would be within an after() function on the server side).
You can paste this comment into Claude and it should handle the refactor just fine.
Note with the changes in analytics scheduling, you will lose out on real time analytics in favor of better time to first load. So keep the trade-off in mind.
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'm a fan of the posthog product but agree with the site. I appreciate the retro styling and all but opening all the windows for everything is disorienting and kinda breaks web navigation that we have all gotten used to for the past 30 years.
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.
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 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.
Hey, Rafa from PostHog here :)
We've always been open source, so I'm not sure I understand what this is about! This is linking to our `posthog-foss` repository which has been a thing for years now, it's simply the main repository without the `ee/` folder - which is not a folder we have a lot inside anyways, we've never tried hiding anything behind it intentionally.

Open sourced ?! I believe it was open source from day one.
Does anyone know what the context for this is? Because https://github.com/PostHog/posthog exists as well
From the repo's about section: PostHog FOSS is a read-only mirror of PostHog, with all proprietary code removed. NOTE: This repo is synced automatically from the main PostHog repo. Please raise any issues and PRs there.
My assumption is that its based on that repo but with the "ee/" folder removed, per https://github.com/PostHog/posthog#open-source-vs-paid
Presumably so folks can be sure they're not accidentally pulling in proprietary code.
From the repo you linked:
> This repo is available under the MIT expat license, except for the ee directory (which has its license here) if applicable.
> Need absolutely 100% FOSS? Check out our posthog-foss repository, which is purged of all proprietary code and features.
The PostHog Enterprise license (the “Enterprise License”)
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”
It's also worth noting that in 2023 they abandoned their Kubernetes support which was relied upon by a full 3.5% of their users: https://posthog.com/blog/sunsetting-helm-support-posthog
In their rationale for this:
> We also learned that the tools to do that automation just don't exist. We kept finding new failure modes. When onboarding a new customer we would have to vet their engineering team for Kubernetes experience so that we'd be confident they could help us debug issues in their PostHog deploy.

It seems like an odd thing to run locally with so many dependencies.
we went from batteries not included to BYOAi
Would love for you to try Amplitude. We've put a lot of work into making sure the core is usable. We've also started to fix a lot of the most common complaints about our pricing.
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.
They've been using AI to shove a lot of AI into their product and trying to force everyone to use AI. I really don't understand the why of any of it. The product was working great for what it needs to do. I don't need AI to make guesses about data for me and I especially do not want _yet another product_ trying to write features in my codebase (which is their latest push).

founder here, what specifically do you use posthog for that you now find hard to find?
I just recently switched to posthog self hosted and it works fine
Spent a day trying to get it running 2-3 weeks back. Gave up after a day.
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?
PostHog has always been open source.
Please update title accordingly.
What the actual fuck is going on with web development nowadays?
Look at the sheer number of ancillary files in this repo:
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?
Do people normally check in dot files? I find that strange but perhaps I am in the minority here.
The sheer number of files in the root of that project is making my OCD itch like crazy. That would drive me insane.
The AGENTS.md is interesting, apparently the primary most important principle is, "Avoid em-dashes like the plague".

Needs (2020) I guess?
Very interesting but why would they do this?
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.
Lol, is github down again?
Congratulations!
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 .
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?
