Nostalgia Utils

A love letter to the computers of the past. Boot a real PC in your browser, listen to a 56k modem handshake, watch the screensavers of your childhood, and more; no time machine required.


90s Website Maker
Build a gloriously retro homepage with tiled backgrounds, marquee text, and a hit counter, then download the HTML.
Blue Screen Maker
Craft a pixel-perfect retro blue screen or error dialog with your own text. Go fullscreen or download it as an image.
Cassette Mixtape
Play your own songs on a virtual tape deck with spinning reels, tape hiss, and a printable J-card label.
CRT / VHS Filter
Give any photo scanlines, RGB bleed, curvature, and VHS tracking glitches, then download the retro result.
Defrag Simulator
Relive the oddly satisfying block-shuffling of a 90s disk defragmenter. Completely useless, completely mesmerizing.
Dial-Up Simulator
Hear the full 56k modem handshake again, from dial tone to connection, with an authentic "Connecting..." dialog.
Fake Install Wizard
Click Next through a pitch-perfect 90s setup wizard, complete with a joke EULA and a progress bar that hangs at 99%.
Pager Code Translator
Decode classic beeper codes like 143 and 07734, and spell words on an upside-down calculator display.
Punch Card Generator
Encode a line of text on an 80-column punch card with authentic IBM 029 keypunch holes, then download it.
Retro PC
Boot a real x86 PC in your browser and land at a genuine DOS prompt. Actual emulation, not a mock-up.
Retro Screensavers
Starfield, bouncing DVD logo, mystify lines, matrix rain, and more classic screensavers in fullscreen glory.
T9 Keypad
Text like it's 1999 on a classic phone keypad. Multi-tap your way to a message and remember why texts used to be short.
TV Sign-Off
Color bars with the 1 kHz tone, a test card, analog static, and the full end-of-broadcast-day sequence.
Virtual Pet
Hatch and raise a pixel pet that lives in real time. Feed it, play with it, and don't let it get grumpy.
