These are the Halloween social media posts from brands in October 2026 that we would show anyone planning next year's. Every pick is a real post from the posts.design library, chosen by hand and grouped by the idea behind it, so each group doubles as a Halloween marketing idea you can borrow.

All 18 were posted on X between October 1 and Halloween, by software companies, games brands and household names from Hello Kitty to KitKat. Few of them are ads in the usual sense: most keep the brand's own logo, mascot or product and change one thing for the season.

01–03

Put the logo in costume

  1. 01

    Carves the Octocat into a real pumpkin and films it glowing on a dark street, while 'happy halloween' types out in white monospace, so the logo is the jack-o'-lantern and the copy is two words.

    Morphs the Vercel triangle into a small window character, then wraps it as a mummy and caps it as a vampire with a red bow tie, so the brand's own shape wears every costume.

  3. 03

    Records the real dub.co homepage and lets small eyes open inside the bowls of the 'd' and 'b', so the seasonal joke is an easter egg in the wordmark with no extra artwork.

Dress up the mascot

  1. 04

    Keeps Hello Kitty's face and bow and changes only the costume and palette: a pumpkin hood, a star-dotted purple bow and a lavender web, so the character stays recognisable as the season changes.

    Puts Razer's snake mascot in a witch hat on a jack-o'-lantern under a full moon, then points the caption at a Halloween sticker pack, so the greeting doubles as a product tie-in.

    Draws the seasonal bat in Notion's own sketched line style, cuts about once a second on black with plain white type, and ends on the logo with the bat peeking in. Posted on October 2.

  4. 07

    Shows one round black character in four costumes, pumpkin, reaper, vampire and ghost, in a single 2x2 grid, so one square carries the range and invites a favourite.

Make the product the joke

  1. 08

    Makes the problem the horror, 'Nothing scarier than a spreadsheet with 47 tabs', with a ghost in one grid cell and the upload box below, so the joke lands on the product.

  2. 09

    Lets one small spider crawl across an otherwise normal project tracker for eight seconds, with a web pun in the caption, so a single animated detail is the whole Halloween treatment.

  3. 10

    Shows a coriander KitKat on a field of coriander and asks whether it is a trick or a treat, so the product is the dare and the replies do the rest. The image itself has no Halloween props.

Hide a game in the product

  1. 11

    Turns the Copilot chat screen into a jumping game: a pumpkin-headed figure climbs platforms collecting candy with a score in the corner, so the post gives a reason to open the app.

    GitHub80.4k+ views on X

  2. 12

    Cuts a horror-game trailer at about a shot a second, from 'Press E to answer' to a corn maze of glowing-eyed skeletons, then dares people to find the game inside Lovable.

Tease a Halloween drop

  1. 13

    Opens the season on October 1 with one glowing jack-o'-lantern face between bursts of glitch static and a three-word caption, so the look announces something before saying what.

  2. 14

    Announces a limited-time Pumpkin Bot for X with a silent six-second loop of one orange pumpkin that squashes and blinks, so a seasonal feature arrives as one shape and one line.

Hand it to creators

  1. 15

    Demos the feature as a costume change: one dusk street scene with a Frankenstein and a furred creature swapped in, and a three-step caption on how to recast yourself.

    Gives the feed to one artist: four glossy 3D scenes of jack-o'-lanterns, stairs and skulls in one purple, orange and pink palette, credited by name in the caption.

Turn the event into an invitation

  1. 17

    Turns a hackathon notice into a Halloween poster with one lilac spider web and 'best costume wins' in the subtitle, while date, venue and sponsors stay readable in fixed bands.

  2. 18

    Sells a masquerade as a physical invitation: an embossed envelope, a masked portrait sliding out and one line, 'You're invited to a secret halloween masquerade', with partners below.

Halloween marketing ideas to borrow

  • Dress the logo, not a stock pumpkin. GitHub, Vercel and Dub kept their own mark and made it the costume.
  • Keep the mascot, change the costume. Hello Kitty and Razer stayed recognisable because only the outfit and palette moved.
  • Make the product the punchline. Airtable's 47 tabs and Superhuman's spider are jokes that end on the fix.
  • Give people something to do. A game, a vote or a recast gets replies that a greeting does not.
  • Start early. Tesla and Notion opened the season on October 1 and 2, four weeks before the night.
  • Keep event details readable. You.com and Boardy let the theme set the mood and kept date, place and partners plain.
