Core Idea SpecForge is a local-first, spec-driven workflow studio that helps developers convert open-source trend evidence into showcase-worthy project blueprints. It integrates trend radar, scoring engine, and workflow simulation to provide a visual tool covering the entire process from inspiration discovery to project planning.

In the fast-paced tech iteration era, developers often face the dilemma: how to find valuable tech trends and turn them into showcase projects? Traditional methods (passive browsing GitHub Trending or social media) lack systematic ways to evaluate and convert these trends.

SpecForge was born to solve this problem. As a local-first, spec-driven workflow studio, it aims to help developers turn open-source trend evidence into concrete product blueprints. Unlike tools relying on real-time data crawling or LLM API calls, SpecForge uses fixed datasets to ensure demo stability and reproducibility.

Design Philosophy

1. Trend-driven product direction: Identifies key tech directions from high-star open-source repos (4 persistent themes: learning path building, developer knowledge discovery, visual AI workflow builders, spec-driven development tools).
2. Transparent scoring model: Multi-dimensional evaluation (tech depth, demo appeal, feasibility, moat, risk) to calculate a comprehensive portfolio score.
3. Simulation-first workflow: Allows pre-development workflow simulation to assess confidence and risks.

Functional Features

• Trend Radar: Fixed high-star GitHub repo dataset for trend overview (avoids API instability).
• Repo Scoring Engine: Multi-dimensional score calculation.
• Interactive Workflow Graph: Visualizes deterministic build processes.
• Guardrails & Evidence Switch: Adjust constraints/evidence to observe impact on project success.
• Exportable Markdown Blueprint: Generates README-ready project plans for portfolio展示.

Tech Stack

• React 19 (UI framework)
• TypeScript 6 (type safety)
• Vite 8 (build tool)
• Vitest (unit testing)
• Lucide React (icon system)

Code Structure

• src/data/repositories.ts: Fixed dataset with source links.
• src/lib/scoring.ts: Converts multi-dimensional factors into portfolio scores.
• src/lib/workflow.ts: Generates workflow nodes, events, risks, confidence, and delivery scores.
• src/lib/exporters.ts: Exports Markdown project plans.
• src/App.tsx: Connects dashboard, selectors, charts, timelines, and export flows.

SpecForge uses transparent, authoritative data sources:

• GitHub high-star baseline (≥100k stars)
• GitHub AI repos (≥20k stars)
• GitHub MCP repos (≥5k stars)
• GitHub Trending and OSSInsight AI trend pages
• Hacker News discussions on spec-driven workflows and composable agents

Detailed data source info is recorded in docs/RESEARCH.md.

• Tech Learners: Systematic way to find valuable learning directions, prioritize high-value projects.
• Portfolio Builders: Turns scattered tech interests into structured project plans; exportable Markdown blueprints reduce entry barriers.
• Tech Decision Makers: Quantitative trend evaluation; simulate different strategies to assess project success probability.

Planned improvements:

• Add scoring profiles for backend, AI, data, and frontend portfolios.
• Implement CLI exporter for blueprint generation from checked-in configs.
• Add optional real-time GitHub fetcher with cache fallback.
• Support repeatable screenshot and demo video generation.
• Publish example blueprints of real portfolio projects.

SpecForge represents a shift from passive information consumption to active decision framework building. It systematizes the process of trend discovery, evaluation, and conversion, providing developers with a structured thinking tool.

For developers looking to enhance tech sensitivity and project planning skills, SpecForge is not only a usable tool but also a valuable architecture example (local-first design, transparent scoring, exportable workflows).
