animate: an open-sourced "Level 4" from a YouTuber with 180k subscribers, 1,500 stars in a month

On 2026 Oct 6, YouTuber Chase Hannegan posted a 14-minute video titled "Claude Now Does Video (FOR FREE) Thanks To JavaScript". The first resource in the description says "Free animate skill", and the repo is linked there. By 11-06, the video had 218k views and the repo had 1,562 stars and 202 forks. It took off on the author's own channel, plus Anthropic's official Claude Motion launch two days later. Followers can't borrow either of those.

What it is

An open-source skill (plugin) for Claude Code. You type one line, /animate a 45-second history of the bicycle, cut paper (a 45-second paper-cut history of the bicycle), and it draws the animation frame by frame on a web <canvas> page, synthesizes a soundtrack with code, then uses a headless browser to capture frames and ffmpeg to encode an MP4. No video-generation model is involved anywhere in the process. Claude writes the code that draws every frame, and the same frame comes out identical every time.

Ships with 7 styles: paper cut, pen crosshatch, riso print, sketchbook, manim-style math explainers, pixel art, and isometric line art. The README also has an "eighth style": give it a few reference images or a video, and it measures the palette, line weight, texture, and edit rhythm, saves the result as a new style, and you can reuse it.

Its most careful feature is "confirm before drawing." Before it starts, you approve three things: the story outline (how many parts and what each covers; it checks facts online), two to four style frames, and the full storyboard. Only after all three are approved does it start animating. After rendering, it reviews its own output: whether cuts land on the beat, whether text gets clipped, whether the loudness is high enough. It can also add ElevenLabs narration with word-level timing, cut to the beat of a song you provide, drop real screenshots of your product page into the animation, and export one asset in four aspect ratios: 9:16, 1:1, 4:5, and 16:9.

Why it took off

First, the author is the channel. Chase AI has 183k subscribers and focuses on Claude Code. Over the past two months, most of his videos got between 50k and 420k views, and his description links to his paid community. That 10-06 video walks through making videos with Claude Code in four parts. Part one is just a prompt (he ran the same prompt at low, high, and extra-high thinking effort, said the extra-high run took about 8 hours, and noted that low and high were already enough). Part two adds a loop of screenshots and review. Part three feeds in reference images. Part four packages the whole workflow as a skill, which is this repo. By views, roughly every 150 views turned into 1 stars (estimate).

Second, two days later the official launch pushed the topic onto the trending charts. 10-08 Anthropic launched Claude Motion, first for Team and Enterprise plans, and 10-09 opened it to all plans. "Claude can make videos" instantly became a web-wide topic, and a TikTok explaining Claude Motion got 340k views. People who wanted something "free, local, with custom styles" searched and found animate. Trendshift's daily data shows its first wave of stars landed on 10-09 (+41) and 10-10 (+145). 10-10 also reached #17 on Trendshift's JavaScript chart, and that was its only appearance for the whole period.

Third, the README's hero image is built to be reposted. The first image is one frame from each of the 7 styles, tiled together, with one install command below it. Instagram and TikTok accounts running "comment ANIMATE and I'll DM you the link" promoted it from 10-09 to 10-21: githubsignals' TikTok got 22.9k views, a Vietnamese account, ainativelab, got 14.6k views, and Pedro | AI Technologist named cth9191 directly on Instagram.

Fourth, it got revived again in early November. From 10-15 to 10-29 it gained only 16 to 39 stars a day. From 10-31 to 11-05 it was back to 56 to 103 a day. Over the same period, anidoodle, another style-focused skill, gained only 7 to 22 a day, so the whole category wasn't surging. The timing matches several "Comment "animate" to get my Claude Video Editing Masterclass + Skills" posts the author put up on Instagram (@chase.h.ai) between 11-02 and 11-05. I couldn't verify whether the DMs sent this repo (inference).

The product is complete enough that people who watched the video and installed it stuck around: forks make up 13% of stars, so plenty of people actually installed it. But that isn't what drove the growth. The repo has had no commits since 10-05, no releases, and no merged PRs. The stars climbed while the author stopped updating entirely.

Who it's competing with

Crowded. After 9-22 Opus 5.5 launched, "drawing animation frame by frame in JS" first went viral in a batch of viral videos, then the official team turned it into a feature. Numbers come from GitHub and Trendshift, 11-06.

In this table, animate sits in the middle. It has the fewest styles; its strengths are its narrative rules (8 short-film structures, rules like "put the loudest moment right after silence") and the three confirmation gates.

The last row is worth a closer look. Around 11-01, Mr omi posted "How to Make Viral Animated Shorts Using Claude", which got 5k views in 629 days. His repo picked up over a thousand stars within days, using the same playbook as animate. In this category, whoever has the video audience gets the stars.

Could I follow it?

Building a "Claude code animation" skill today probably won't get you this kind of traction. Three reasons: first, the category already has several projects with tens of thousands of stars, plus an official feature; second, animate's traffic came from its author's own channel, which followers don't have; third, the wave from the official launch has been over for almost a month.

Single-style small skills already exist and haven't done well: 0xS4N4TG/papercut-explainer only does paper cut and has 139 stars; YIAN6557/eian-riso-broll only does riso and has 358 stars. Both were created in mid-October.

What you can take is the playbook: a tutorial video and a free repo, with the repo as the final part of the video, plus a "see everything in one image" hero image that accounts can repost after a screenshot.

If it were you

C: worth learning from, but copying it isn't a great deal. It took off on the author's own 180k-subscriber channel and on the timing of an official launch, and you can't borrow either. Several similar projects already have tens of thousands of stars, plus an official feature. What's worth learning is the "video + free repo" combo. Use it again with a different topic next time.

Who it suits: people who already have a content channel. Creators on YouTube, Bilibili, Xiaohongshu, or Douyin with tens of thousands of followers who cover AI tools, already have a workflow they use, and are willing to package it as an open-source skill.

Who it doesn't suit: people with no audience of their own who plan to rely only on organic GitHub traffic; people who want to build another general-purpose "multi-style code animation" skill (projects with 66, 36, and 32 styles already exist); people who want to break in with a single style (both of the projects above have stalled at a few hundred stars).

How to do it:

• Change the ecosystem, not the style. There's already huashu-art-motion in Chinese; I haven't seen a substantial equivalent in Japanese, Korean, or Spanish-speaking communities (inference, I didn't check each one). Sample videos that narrate in the local language and cover local topics will do more for you than adding more styles.
• Build the part it didn't finish. The README says "coming soon" for a WebGL dynamic-design style (raymarching 3D, motion blur, glow). It hasn't shipped, and the project itself admits the gap.
• Or build one specific use case and do it best: store preview videos for apps, 1-minute summary animations for papers, vertical knowledge cards for Xiaohongshu. These are easier to pitch than a general "can draw anything" tool, and easier to repost.
• Whatever you build, put a collage of all the finished outputs in the README hero image, with one install command below it.

How to get users: video first, then the repo. Record a 10 to 15 minute tutorial in parts (from "just write a prompt" to "package it as a skill"), with the last part being your repo, and put the link in the first line of the description. Cut three to five vertical clips for TikTok, Instagram, and Xiaohongshu, each with a line like "comment a keyword to get the link." Send them directly to accounts like githubsignals that repost GitHub projects. When the buzz fades after two or three weeks, post another keyword lead-magnet round and re-promote the old videos. That's how animate's second wave happened (inference).

When to launch: one to two weeks before or after the next major model release or official video feature. Animate's video went out two days before Claude Motion and rode the search demand from the official launch. That wave is over now, so don't rush to catch up. Prepare sample reels and videos, and wait for the next moment.

Signs you've misread the situation: ① Before mid-December, someone without their own channel, relying only on GitHub and Reddit posts, gets a similar skill past 1,000 stars. That would show the category can earn stars from the product alone, which makes it worth building. ② Animate keeps gaining at least +30 a day through December, even though its author has stopped promoting it. That would show real demand, not just viewers clicking along. ③ Claude Motion builds custom styles, your own music, and multiple aspect ratios into the official feature. In that case, there's little room left for an open-source skill on this path.
