Why Version Control Your Prompts?
Just like software developers version their code, prompt engineers should version their prompts. Prompt engineering is inherently iterative — you test, refine, test again, and often need to roll back when something breaks. Without version control, you're working without a safety net.
This tool helps you track every change to your prompts, compare different versions side-by-side, and restore previous versions when needed. It's especially valuable when optimizing prompts for performance, accuracy, or token efficiency.
Benefits of Prompt Versioning
How to Use This Tool
- Enter or paste your prompt — Write your prompt in the editor area. Give it a descriptive name.
- Add version notes — Explain what changed or why you made modifications. Keep notes concise but informative.
- Save the version — Click "Save Version" to create a snapshot. Versions are numbered automatically.
- Compare versions — Select two versions from the history panel to see a side-by-side diff.
- Load previous versions — Click the history icon to restore any saved version to the editor.
- Delete old versions — Remove versions you no longer need to keep your history clean.
Best Practices for Prompt Versioning
Save Before Major Changes
Always create a version before making significant modifications. It only takes a second and gives you a clear restore point.
Write Clear, Actionable Notes
Instead of "updated prompt," write "Added explicit JSON output format to reduce parsing errors." Future you will thank present you.
Make Small, Focused Changes
Change one thing at a time between versions. This makes it easy to identify what improved or broke performance.
Track Performance Metrics
In your version notes, include relevant metrics: accuracy, response time, token count, or user satisfaction scores.
Example Version Notes
v1.0 → v1.1
"Added 'Be concise' instruction — reduced average
response length by 40%"v1.1 → v1.2
"Added explicit boundary: 'Do not discuss competitors'
— fixed off-topic responses"v1.2 → v1.3
"Reverted role definition to v1.0 style — new format
caused degraded code quality"Frequently Asked Questions
Are versions saved permanently?
Versions in this tool are stored in your browser's session. For permanent storage, copy your prompts to a document or use a dedicated prompt management platform.
How many versions should I keep?
Keep at least your last 5-10 working versions. Delete versions that were clearly mistakes or dead ends. Always keep versions that were deployed to production.
Can I compare more than two versions at once?
Currently, you can compare exactly two versions at a time. For complex comparisons, compare pairs sequentially (v1 vs v2, then v2 vs v3, etc.).
Should I version test prompts or only production prompts?
Version both! Test versions help you track your experimentation. When promoting to production, clearly mark it in the version notes.
