While frameworks like LangChain and Haystack are powerful, building your own custom framework gives you complete control over architecture, performance, and business logic. Perfect for specialized use cases.
Existing Frameworks vs Custom
Using Existing Frameworks
- ✓Fast to start: Pre-built components, documentation, community support
- ✓Battle-tested: Production-ready patterns and edge cases handled
- ✗Limited control: Constrained by framework's architecture and opinions
- ✗Dependencies: Framework updates may break your code
- ✗Overhead: Includes features you don't need, larger bundle size
Specialized Requirements
Your use case has unique needs that existing frameworks don't address well. Custom framework lets you optimize for your specific domain.
Performance Critical
Need maximum speed and minimal overhead. Custom framework eliminates unnecessary abstractions and gives you direct control.
Deep Integration
Tight coupling with existing systems, databases, and internal APIs. Custom framework integrates seamlessly with your tech stack.
Learning & Control
Understand every piece of your agent system. Building from scratch teaches you exactly how agents work under the hood.
What We'll Build
1. Core Agent Loop
The fundamental observe → reason → act cycle that powers agent decision-making and execution.
2. Tool Registry & Execution
Dynamic tool registration, schema validation, and safe execution environment with error handling.
3. Memory System
Short-term context management and long-term storage with retrieval for maintaining conversation state.
4. Production Patterns
Logging, monitoring, error handling, rate limiting, and deployment strategies for real-world use.
💡 Framework Design Principles
- •Simplicity first: Start minimal, add complexity only when needed
- •Composable design: Small, reusable components that work together
- •Type safety: Use TypeScript/Python type hints for reliability
- •Testability: Design for unit testing from the start
