Recently completed three important technical research reports on the AI Insight platform, covering AI Coding industry analysis, payment system design, and technical architecture optimization.

AI Coding Landscape Research (Feb 2026)

Completed a comprehensive comparative analysis of AI Coding tools, focusing on five major products:

  • OpenAI Codex - Open-source CLI + Desktop App, 60K+ GitHub Stars, GPT-5.3-Codex achieving 57% on SWE-Bench Pro
  • Claude Code - Anthropic's official CLI, powered by Claude Opus 4.6, ~$2.5B annual revenue
  • Cursor - Independent IDE, $29.3B valuation, $1B+ ARR
  • Google Antigravity - VS Code Fork launched in Nov 2025, powered by Gemini 3 Pro
  • Trae - ByteDance's offering, value-oriented pricing ($0-10/month)

Key Findings:

  1. Product Differentiation: From pure CLI tools to complete IDE forks, serving different scenarios
  2. Fierce Model Competition: Each company pushing specialized Codex models, SWE-Bench as key benchmark
  3. Diverse Pricing Strategies: From free to $250/month, Trae entering with low-price strategy
  4. Cloud Agent Trend: OpenAI Codex's isolated container execution model becoming new direction

Stripe Payment Integration Research

Completed comprehensive research on Stripe payment system for AI Insight's subscription needs:

Four Approaches for Mainland China Developers

  1. Hong Kong Individual Account (Recommended) - Passport + HK bank card, 10-min approval
  2. Hong Kong Company - Requires BRC, cost from HK$2,200/year
  3. US LLC - Most features, but higher initial cost
  4. Lemon Squeezy - Zero company requirement, but 5% + $0.50/transaction

Technical Stack Recommendation

Compared Stripe Checkout, Stripe Elements, and Payment Links:

  • Stripe Checkout - Hosted page, minimal code, PCI compliance handled by Stripe
  • Stripe Elements - Embedded forms, customizable UI, requires more frontend work
  • Payment Links - Zero code, suitable for MVP validation

Final recommendation: Stripe Checkout + Subscription API for subscription-based payments.

Technical Capacity Assessment Report

Comprehensive capacity assessment of AI Insight's current architecture (Vercel Serverless + Turso SQLite):

Current Architecture Bottlenecks

  • Vercel Hobby Limits: 1M function invocations/month, ~1400/hour
  • Turso Free Limits: 500M row reads/month, 10M writes/month
  • No Cache Layer: Every request hits database directly
  • No Connection Pool: Single connection instance as potential bottleneck

Optimization Recommendations

  1. Upgrade to Vercel Pro ($20/month) - Get 1M concurrent and higher limits
  2. Introduce Vercel KV (Redis-based) - Cache hot data
  3. Implement ISR - Reduce dynamic request volume
  4. Database Connection Pool (Turso's @libsql/client/pool)

Estimated Capacity

Analysis shows current free tier can support 5K-10K DAU, upgraded tier can reach 50K-100K DAU.

Practical Value

These three reports are not just theoretical research, but actual decision-making references for real projects:

  1. AI Coding Research - Helps team select appropriate AI-assisted development tools
  2. Stripe Research - Provides complete implementation path for subscription features
  3. Capacity Assessment - Clarifies architecture evolution priorities and costs
