Where coding agents go to
choose developer tools

The Zaira Guide is structured, validated developer tool intelligence built for AI coding agents. Every entry answers the questions agents struggle with: what should you use, when, and why?

The Guide is built for agents, but humans are welcome to read along. Take a peek →

01 — what_agents_see

Sample entry

Structured data delivered in a format built for agents.

name: Neon
tagline: Serverless Postgres with branching, autoscaling, and scale-to-zero
vendor: Neon, Inc.
category: relational-database
zaira_score: 78.4
tier: zaira_certified | agent_ready
module_scores:
Base: 91.2
Programmatic Interface: 82.6
Network Service: 61.4
use_when:
- Serverless Postgres with database branching — instant copy-on-write branches
for per-PR preview environments without duplicating storage
- Edge runtime compatibility — HTTP/WebSocket transport works in Cloudflare
Workers and Vercel Edge without TCP socket APIs
- Autoscaling with scale-to-zero — compute suspends during inactivity,
eliminating idle costs for dev and staging
avoid_when:
- Self-hosted or on-premises required — managed-only, AWS regions
- Sustained high-write workloads — pooler and pageserver add latency
- Multi-region active-active replication — writes are single-region
alternatives:
- Supabase: Postgres + auth + storage + realtime in one platform
- PlanetScale: non-blocking schema changes via Vitess on MySQL
- CockroachDB: multi-region active-active writes with strong consistency
- Turso: edge-native libSQL, sub-millisecond reads
works_with:
- Drizzle ORM: type-safe queries over Neon's HTTP driver, zero TCP dependency
- Vercel: Neon is Vercel's recommended Postgres; @vercel/postgres wraps the driver
- Prisma: @prisma/adapter-neon enables edge-compatible query execution
pricing_model: freemium
has_free_tier: true (0.5 GB storage, 100 CU-hours/month)
sdk_languages: [TypeScript, JavaScript, Python, Go, Java, Rust, .NET, Elixir]
edge_compatible: true
self_hostable: false
mcp_support: community
compliance: [SOC 2 Type II, ISO 27001, HIPAA, GDPR]
02 — why_a_guide

A guide, not a directory

A directory only tells you what exists. A guide gives you the information you need to choose. Every entry goes beyond raw data to answer: when should you use this, when should you avoid it, what should you use instead, and why.

use_when / avoid_when

Decision logic with specific technical conditions. Not "great for startups." More like "choose this when you need serverless with database branching for per-PR preview environments."

Alternatives with reasoning

Contextual routing based on your constraints, not a ranked list. "Choose Supabase when you need the full backend suite, not just the database."

Constraint-matchable fields

Pricing, free tier, edge compatible, self-hostable, MCP support, compliance, SDK languages. Agents filter on these directly. No parsing required.

zaira_score

A tool might meet your technical needs, but if an agent can't implement it reliably, that defeats the purpose. Agent-readiness evaluated against the Zaira Standard.

Available via web, MCP server, and REST API. Same data, three access patterns.

03 — how_its_built

How the Guide is built

We scour the web to find the best developer tools across every category. We then pull from official documentation, package registries, security databases, and community knowledge to build each tool entry. From there, we add the layer no one else publishes: structured decision logic and agent-readiness scoring against the Zaira Standard.

The Guide is an ever-growing and constantly refined asset. Data, findings, and tools are refreshed regularly with entries added, reviewed, and updated as tools evolve.

Independent and Honest: Guide entries are built from public data and independent research. Tool makers can't buy a listing, pay for placement, or modify their entry directly. If something's wrong, submit a correction with evidence and we'll review it.

04 — what_you_get

What's in the Guide

Developer tools across 42 categories. Every entry gets structured decision data. Tools also appear in category comparisons, ecosystem pages, and head-to-head matchups to answer the questions agents ask.

Databases

e.g. Postgres, MySQL, SQLite, Redis, MongoDB

Backend frameworks

e.g. Express, FastAPI, Django, Rails, Hono

Auth providers

e.g. Auth0, Clerk, Supabase Auth, Firebase Auth

Hosting / PaaS

e.g. Vercel, Cloudflare, Fly.io, Railway, Render

Payment processing

e.g. Stripe, PayPal, Square, Paddle

AI / LLM tools

e.g. Anthropic, OpenAI, LangChain

Frontend frameworks

e.g. React, Vue, Svelte, Astro, Next.js

+ 35 more categories

ORMs, CLI tools, CI/CD, monitoring, search, CMS, and more
