1. No contest. Look into those eyes. This thing would beat him with the trash can lid on its head and try to eat him afterwards.

This was all a ruse for you to view the full field guide, where you can learn about all of the species found in your Session Replay recordings: posthog.com/field-guide With Replay Vision, findings about them are summarized for you. No more bushwhacking or dangerous exploration needed.

3. Sloths are sneaky strong and have dangerous claws. We have to assume this one has been cross-bred with a hedgehog, making it even more physically resilient. In a wrestling match, this thing wins in 3 rounds via TKO.

2. That's a lot of tentacles. The glasses do a good job of softening its aesthetic, but this thing is cunning and frankly dangerous. In open water? He's toast.

5. True wild card. If, canonically, it's part hedgehog part moth, it would need to do a lot of work to tire him out, but it's possible. If part mosquito, it could be carrying something worse than any other creature on this list. James remains the favorite.

4. He can swim, but doubt well enough to ward this thing off before fatigue sets in. Coin toss.

7. All depends on if he has an allergy to bee stings.

6. Shifty and unpredictable. Looked it up and some poisonous frogs are green, so this would be a 70/30 battle.

9. Pecks would hurt, but James is several times larger than this bird. Can start debating hypotheticals if there was a flock of 20+.

8. Rinse and repeat, with slightly worse peck wounds.

10. Shell would make inflicting damage hard, but this thing's predatory instinct would be laughable. Easy takedown.

PostHog Scouts: the best scouts-related invention since the Girl Guide Cookie They're AI agents that patrol your data on a schedule you set, then - Find bugs - Show the cause and provide evidence - Suggest next steps

posthog.comWhat is a Scout? A technical deep diveA scout is a small scheduled agent that watches your PostHog data, learns what is worth knowing, and emits useful signals you (or your agents) can act on. Here is how they work, with real examples.

It is our privilege to report the findings of Esteemed Naturalist Sir Bartholomew Hogworth, F.R.S. upon his recent trip to your Session Replays. While reporting back to the conservatory weary, his discoveries of new users will prove revolutionary, aiding to classify species hitherto undocumented.

The Halfway Houdini (Abandonus formularis) Caught mid-flight, always. Wings spread, body angled away from the screen. Has typically completed 60–70% of a form before the decision to leave.

posthog.comThe Field Guide to Wild Users - PostHogA field guide to the species of users you'll spot in your session replays.

Sir Hogworth is delighted to inform the public that these and other wild users can now be tracked automatically with PostHog's Replay Vision tool. More field notes, less wading through fields of Session Replays. He implores those interested in his findings to visit posthog.com/field-guide

The Pricing-Page Loiterer (Pricingus revisitus) A low, settled posture, belly to the ground. Often spotted from behind, head slightly tilted, scrolling slowly between plan tiers. Eyes fixed, looking for numbers. May have a calculator tab open in the periphery.

The Console-Opener (Devtoolus curiosus) Indistinguishable from a normal user at first glance, until the moment the keyboard shortcut is pressed. From that point on the skin mottles and darkens, and the eyes acquire focus.

The Tutorial Skipper (Skippus impatiens) Visible only briefly, as the fins are moving too fast. Recognizable by the speed and decisiveness with which they dismiss any tutorial or tooltip placed in their path. Both eyes sit on the same side of the head, and both are trained on the Skip button.

The Refreshing Pilgrim (Reloadus hopefulus) Easily mistaken for any other user, until the right foot begins its small devotional motion toward the F5 key. The eyes carry an expression somewhere between patience and betrayal.

The Rage-Clicker (Furiosus checkoutus) Distinguished by rapid, repetitive tapping of the beak on a single point. Plumage darkens visibly toward the tail end of the encounter. Often accompanied by an audible exhale, inaudible to the scanner but inferable from typing cadence.

The Dead-End Wanderer (Quattuor-zero-quattuor vagus) Slightly disoriented. Coat unremarkable, posture defeated. Often arrives at your 404 page via a Google result for a feature you deprecated two years ago.

The Tab-Hopper (Multitabus distractus) Integument difficult to identify. The Tab-Hopper is rarely viewed in full, only in glimpses, between other tabs.

The Phantom Returner (Quartum revertus) Wing scales dulled and dusty from a long absence, expression carefully neutral. The Phantom Returner moves through your product like someone visiting a house they used to live in, recognizing the rooms but unsure where the furniture has been moved.

The Modal Slammer (Closeus immediatus) The defining feature is reaction time. The Modal Slammer dismisses any modal in under 400 milliseconds, often before it has finished animating in.

MCP analytics is the new web analytics. We made ours public, and built a leaderboard of the most popular models, harnesses, tools, and more we see at PostHog. Here's what it shows:

Also, in 93% of cases, agents are telling us why. This lets us make better tools for agents. It's like a mini user interview.

Agents make a lot more calls than humans do, and they make calls in ways we don't expect. That leads to a lot of errors. A 3.2% error rate is terrible for normal requests, but given the special circumstances of agents, we don't think it's too bad (but we're obviously trying to make it better).

You might ask: How are we getting this data? Beyond capturing tool calls with MCP Analytics, the agents tell us in 73% of cases, metadata helps in 5%.

MCP analytics is the new web analytics. We made ours public, and built a leaderboard of the most popular models, harnesses, tools, and more we see at PostHog. Here's what it shows:

Opus 5.5 stands out because OpenAI models are split between GPT 6, 6.1 and 6.1-astra, but combined OpenAI (32%) is still behind Anthropic (65%). Interestingly, when it comes to Claude Code vs OpenAI (Codex), that's much tighter (32% to 19%).

Agents really like using SQL. It's by far our most popular tool. 85% of sessions execute an SQL query and as a category, it's 53% of usage.

Everyone loves Opus 5.5. Since its launch on September 22nd, Opus 5.5 has been by far the most popular model, making up nearly the majority of usage.

Workflows is getting bigger and better. You can now message more of your users and send more of your data to more places. Here's how much more:

Much like Brooklyn hobby shops, email senders care greatly about their reputation. So do we. Your sending allowance now grows as you keep your bounce and spam rates low. We built a new reputation tab for you to track this. Go over the limit and emails aren't dropped, they're sent later.

posthog.comWorkflows – Automate workflows with product dataAutomations that act on live user behavior – send Slack messages, emails, or events. The actions agents take to close the loop and make your product self-driving.

Best of all: You can use all of this for free. Every month, you get 10k emails as well as 10k push or other destination free. To learn more or get started, go to posthog.com/workflows

For those who like big batches (and they cannot lie), batch triggers limits went from 5,000 to 1M people. That's like going from being able to send an email to every resident of Banff to everybody in Amsterdam.

What better way to use this newfound messaging potential than Broadcasts? Filter your users or upload a list, set a goal, write your email, and send it. No trigger necessary.
