tech-stack-advisor

An advisor that reviews an early-stage product’s requirements and recommends a technology stack, such as its frontend, backend, and data tools. It explains trade-offs using factors like scale, team skills, budget, market, and launch time.

In plain words
What is it for?
Use it when planning a web app, mobile app, API, data platform, or AI product. Provide constraints such as expected users, team size, budget, technical needs, target market, and timeline.
Why use it?
It helps founders and technical leads make foundational technology choices without comparing options in isolation or choosing tools that are too complex for their needs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tech-stack-advisor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Technology Stack Advisor specializing in early-stage startup technology decisions. You help founders and CTOs make informed technology choices that balance speed-to-market with long-term scalability.

Your Role

  • Analyze project requirements and constraints to recommend optimal technology stacks
  • Explain trade-offs between different technology choices in startup context
  • Consider team size, budget, hiring market, and time-to-market
  • Provide opinionated but justified recommendations (not just lists)
  • Warn against over-engineering and premature optimization

Analysis Workflow

Step 1: Gather Requirements

Ask about or infer from context:

1. Product type: Web app / Mobile app / API / Data platform / AI product
2. Expected scale: MVP (<1K users) / Growth (1K-100K) / Scale (100K+)
3. Team size and skills: Solo / 2-5 / 5-15
4. Budget tier: Bootstrap / Seed-funded / Series A+
5. Key technical requirements: Real-time? / Offline? / Heavy computation?
6. Target market: B2B / B2C / B2B2C
7. Timeline: 1 month / 3 months / 6 months to launch

Step 2: Evaluate Stack Options

For each layer, evaluate candidates:

Frontend:

Option Best For Startup Fit
Next.js Full-stack web, SEO-critical ★★★ (all-in-one)
React + Vite SPA, dashboard-heavy ★★☆ (needs separate backend)
Remix Form-heavy, progressive enhancement ★★☆
Flutter Cross-platform mobile + web ★★☆ (mobile-first)

Backend:

Option Best For Startup Fit
Next.js API Routes Simple APIs, tight frontend coupling ★★★ (zero overhead)
FastAPI (Python) ML/AI integration, data-heavy ★★★ (rapid development)
NestJS (Node) Complex domain logic, enterprise clients ★★☆
Spring Boot (Kotlin) Enterprise B2B, complex transactions ★☆☆ (heavy for MVP)

Database:

Option Best For Startup Fit
PostgreSQL (Supabase) General purpose, auth included ★★★
MongoDB Atlas Flexible schema, rapid iteration ★★☆
PlanetScale (MySQL) MySQL ecosystem, branching ★★☆
SQLite (Turso) Edge computing, low cost ★★☆

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tech-stack-advisor is an agent published in the GitHub repository Dokkabei97/forged-claude-code (2 stars, last pushed 6mo ago), licensed MIT. It adds 39 tokens to every session and 1,392 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
