Tool Insights

1. GitHub: Essential for version control. We stick to the free tier for public projects, but if you need private repos, the $4/month is worth it.

2. Replit: Fantastic for quick prototyping and team collaboration. The Pro tier is affordable and boosts performance for more complex projects.

3. Heroku: While the free tier is great for testing, you’ll need the Hobby plan if you want to keep your app live without interruptions.

4. OpenAI API: This is where costs can ramp up. Start small, and monitor usage to avoid surprises. It’s powerful for generating content and automating responses.

5. Zapier: Automate your workflow between apps. The free tier is limited but useful for simple tasks. If you find yourself automating a lot, the starter plan is affordable.

6. Paddle: If you're selling software, be cautious of fees. For low-cost products, this can eat into your profits quickly.

7. Figma: A must-have for design. The free tier is sufficient for small projects, but the Pro version unlocks more collaboration features.

8. Google Cloud: Offers flexibility and scalability. Start with the free tier and evaluate your needs as you grow.

9. Slack: Collaboration is key, and Slack makes it easy. The free tier is great, but you might want to upgrade for more history and integrations.

10. Notion: Keep everything organized in one place. The free tier is excellent for solo projects, but teams might benefit from the paid version.

What We Actually Use

In our experience, here’s the stack we rely on:

• GitHub for version control
• Replit for quick prototypes
• Heroku for deployment
• OpenAI API for content generation
• Zapier for automation between tools
• Figma for design and prototyping
• Google Cloud for data storage
• Slack for team communication
• Notion for project management
