The Panic of a Week's Notice
When Teller.io announced its shutdown with only a week's notice, developers who relied on its API for banking data felt a familiar dread. Their apps, built on Teller's endpoints for transaction data, faced an immediate infrastructure crisis. The pain was acute: losing critical functionality with no clear migration path.
Why This Hurts So Much
Teller.io was a developer-friendly banking API that many indie founders and small fintech teams chose over giants like Plaid or Yodlee. Its simplicity and indie-friendly pricing made it the backbone of countless apps. Now, those same developers are scrambling to find a replacement that offers the same endpoints, documentation, and reliability.
The alternatives aren't great. Plaid is powerful but complex and expensive for small projects. Yodlee has a steep learning curve. Building custom bank scraping is fragile and maintenance-heavy. The market is crying out for a drop-in replacement that prioritizes developer experience and long-term stability.
The Opportunity: A Developer-First Banking API
The MVP is straightforward: build an API that mirrors Teller.io's endpoints, allowing developers to switch with minimal code changes. Provide a simple migration guide, clear documentation, and a pricing model that doesn't punish indie developers.
Key features:
- Same endpoints as Teller.io for transaction data, account info, and authentication
- Step-by-step migration guide with code examples
- Transparent pricing: $49/month for indie developers, usage-based tiers for scaling apps
- Long-term stability commitment to prevent future panic
How to Get Started
- Analyze Teller.io's API docs (if still available) to map endpoints
- Build a proxy layer that accepts Teller-style requests and routes to Plaid or direct bank connections
- Create a migration script that automatically updates API keys and endpoints in existing codebases
- Launch on Hacker News in the same thread where developers are panicking
