Last Updated: 2025-11-15 Target: Production-Ready 1.0.0 Release

⚠️ TODO - Before Finalization

This roadmap is currently in DRAFT status. Before implementation begins, the following steps must be completed:

  • 1. Discuss and agree roadmap - Review with core maintainers and community stakeholders
  • 2. Align issues with roadmap - Create/update GitHub issues to match roadmap phases
  • 3. Create project board - Set up GitHub project board for tracking roadmap progress

Once these steps are complete and the roadmap is agreed upon, this DRAFT marker will be removed and implementation can begin.

Executive Summary

LLM4S is a comprehensive framework for building LLM-powered applications in Scala. While the project has made significant progress with multi-provider support, agent frameworks, RAG capabilities, and observability features, several key areas require attention before reaching production readiness.

This roadmap outlines a structured path to achieve production-grade quality across seven key pillars: Testing & Quality Assurance, API Stability, Performance & Scalability, Security & Compliance, Documentation & Developer Experience, Observability & Operations, and Community & Ecosystem.

Current Status: v0.1.x (Pre-Production) Target: v1.0.0 (Production-Ready) Estimated Timeline: 6-9 months

Current State Assessment

Strengths

✅ Active Development: 158+ commits in 2025, strong momentum ✅ Cross-Platform Support: Scala 2.13 and 3.7 with full cross-compilation ✅ Multi-Provider Architecture: OpenAI, Anthropic, Azure OpenAI, Ollama ✅ Comprehensive Features: Tool calling, agents, RAG, multimodal support ✅ Type-Safe Design: Leveraging Scala’s type system with Result[A] pattern ✅ CI/CD Pipeline: Automated testing, formatting, and release workflows ✅ Good Documentation: Detailed design docs, migration guides, API specs ✅ Community Engagement: GSoC participation, active Discord, regular talks ✅ Maven Central Publishing: Proper artifact distribution ✅ Configuration Management: Centralized ConfigReader with Scalafix enforcement

Identified Gaps

❌ Test Coverage: ~21% test files (target: 80%+ statement coverage) ❌ Integration Testing: Limited end-to-end and integration test scenarios ❌ Performance Benchmarking: No formal performance testing framework ❌ API Stability Guarantees: Still in 0.x versions, no backward compatibility policy ❌ Production Error Handling: Limited patterns for retries, circuit breakers, bulkheads ❌ Security Auditing: No formal security review process ❌ Monitoring in Production: Limited guidance beyond tracing ❌ Deployment Patterns: No reference architectures for production deployments ❌ Breaking Change Process: Unclear migration path for major API changes ❌ Chaos Engineering: No resilience testing framework
