DejaVu keeps a rolling 5 to 25 minute buffer of your screen on disk and saves a clip when you press one key. Unlike ShadowPlay it never turns itself off, and because the buffer lives on disk instead of RAM, a crash becomes a recovered clip on the next launch instead of a loss. Discord voice is excluded from clip audio by default. Works on any GPU with a hardware encoder and records AV1 on modern cards. One exe around 160 KB. No account, no uploads, no telemetry.

Discord Nitro lets you pick a profile theme color, but the banner Discord actually renders isn't that hex — it gets blended ~40% toward black or white depending on brightness. There's no built-in preview, so most people just guess and re-upload until it looks right.
