32+ TikTok video ideas for coding & software

Concrete coding & software video ideas you can film today — each one works on TikTok, Instagram Reels, and YouTube Shorts. Copy an idea, pair it with a strong opener from the coding & software hooks library, and post.

  4. 4.Show the exact git commands you use to recover from a bad commit
  5. 5.Solve one leetcode problem out loud, from brute force to the optimal answer
  6. 6.Show your editor setup and the three extensions you'd never code without
  7. 7.Walk through a merge conflict from scary to resolved in real time
  8. 8.Break down a real interview question and what it's actually testing
  9. 9.Let an AI tool write a function and fact-check every line it produces

  26. 26.Show the keyboard shortcuts that shaved real minutes off your day
  27. 27.Explain an off-by-one bug by walking the loop index out loud
  28. 28.Take a slow function and profile it live to find the actual bottleneck
  29. 29.Show how you write a README so a stranger can run your project
  30. 30.Do a self-taught path video: what you learned in order and what you'd skip
  31. 31.Explain one edge case that broke your code in prod and how you caught it
  32. 32.Answer whether beginners should learn Python, JavaScript, or something else first

Making these work in coding & software

  • Screen-record your editor at a readable font size and zoom into the exact lines. Devs pause to read code, so tiny text or a cluttered screen loses them in the first second.
  • Name the exact error, command, or complexity in your hook. This audience is allergic to fluff and rewards precision; 'use a hashmap' lands where 'optimize it' gets skipped.
  • Only post hot takes you can back with code. Comments will stress-test any claim, and getting corrected on your own hook kills the video's reach and your credibility.
  • Lead with the after, the fix, the one-liner, the passing test, then rewind to the messy before. Nobody watches a slow build-up when the payoff isn't promised up front.
