Not Another LLM Wrapper
DDL to Data uses smart pattern matching — not AI — for instant, deterministic results. No token costs. No rate limits. No hallucinated data.
DDL to Data
- Milliseconds, not seconds
- Deterministic output
- Flat monthly pricing
- Seed databases directly
- Foreign key integrity built-in
- No prompt engineering needed
- Works offline in CI/CD
🤖
Prompting an LLM
- —2-10 seconds response time
- —Non-deterministic output
- —Pay per token/generation
- —Prompt tweaking required
- —Manual relationship handling
- —May hallucinate invalid data
- —Requires API connectivity
Speed Comparison
DDL to Data~50ms
GPT-4 / Claude~3-5 seconds
ChatGPT wrapper tools~5-10 seconds
Time to generate 100 rows of realistic user data
Cost Comparison
$0
per 100 rows with DDL to Data
(within free tier limits)
$0.02-0.10
per 100 rows with LLM APIs
(varies by model and tokens)
For CI/CD pipelines running hundreds of tests daily, LLM costs add up fast.
When LLMs Make Sense
LLMs excel at generating narrative content — product descriptions, user reviews, article text. For that, check out our Story Mode.
Use DDL to Data (Core) for:
- • Realistic emails, phones, addresses
- • Dates, timestamps, UUIDs
- • Foreign key relationships
- • CI/CD pipeline data
- • High-volume seeding
Use Story Mode for:
- • Product descriptions
- • User-generated content
- • Blog posts and articles
- • Support tickets
- • Demo/presentation data
