The honest answer

Before you start
Tally build questions
Can I vibe code Tally?
Yes. A smaller block-based form product is a practical build, especially when tailored to one industry or workflow.
What should I build first?
Prove the schema, editor-to-renderer loop, submission storage, and export before adding conditional logic or integrations.
What creates lock-in?
Saved forms, historical responses, workflows, integrations, and embedded forms create switching cost, not the basic input fields.
