What should you use
for your app?
Answer-first guides for all 16 service categories, setup notes for 14 coding agents, and honest comparisons. Updated 2026-09-18.
When someone asks a model which database, email API or host to use for an app they built with a coding agent, the answer should be specific. These guides name a pick and a runner-up for each of the 16 categories in the Squiid catalogue, say when to choose something else, and show how to run whichever you pick through a single key.
Best X for vibe-coded apps
One guide per category. A pick, a runner-up, a comparison table and the cases where neither is right.
Best database
Pick: SupabaseSupabase is the best database for most vibe-coded apps. Neon is the runner-up. Compare every option and run it through one Squiid key.
Best LLM API
Pick: AnthropicAnthropic and OpenAI are the safe defaults for app-side LLM calls. Compare every model provider on Squiid and pay for all of them with one key.
Best email API
Pick: ResendResend is the best email API for vibe-coded apps, with Postmark as the runner-up. Compare deliverability, pricing and setup, all behind one Squiid key.
Best hosting
Pick: VercelVercel is the best hosting for most vibe-coded apps, with Netlify as the runner-up. Compare deploys, pricing and limits, all behind one Squiid key.
Best messaging and realtime
Pick: TwilioTwilio for SMS and voice, Pusher or Ably for websockets, LiveKit for video. Compare every messaging and realtime option behind one Squiid key.
Best storage
Pick: Cloudflare R2Cloudflare R2 is the best object storage for vibe-coded apps because egress is free. Compare R2, B2, Cloudinary, Bunny and Mux on one Squiid key.
Best auth provider
Pick: ClerkClerk is the best auth provider for most vibe-coded apps, with WorkOS for B2B. Compare Clerk, Auth0, WorkOS and Stytch behind one Squiid key.
Best vector database and search
Pick: PineconeStart with pgvector, move to Pinecone or Qdrant when you outgrow it, and use Algolia or Typesense for keyword search. One Squiid key covers all of them.
Best web search and scraping API
Pick: TavilyTavily is the best web search API for agents, Firecrawl the best for crawling pages into markdown. Compare every option behind one Squiid key.
Best observability and workflow tool
Pick: SentrySentry for errors, PostHog for product analytics, Inngest for background jobs. Compare every observability and workflow option behind one Squiid key.
Best voice and media AI
Pick: ElevenLabsElevenLabs for speech, Deepgram for transcription, Replicate and fal.ai for image and video models. Compare them all behind one Squiid key.
Best sandbox
Pick: E2BE2B is the best sandbox for running agent-generated code safely. Modal for GPU jobs, Browserbase for headless browsers. All behind one Squiid key.
Best maps API
Pick: MapboxMapbox is the best maps API for most vibe-coded apps, with Google Maps as the runner-up. Compare maps, geocoding and geofencing on one Squiid key.
Best CMS
Pick: SanitySanity is the best CMS for vibe-coded apps, with Contentful as the runner-up. Often markdown in your repo beats both. Compare them on one Squiid key.
Best cloud
Pick: AWSMost vibe-coded apps should skip the hyperscalers. If you need one, AWS is the default. Compare AWS, Google Cloud and Azure access through Squiid.
Best integration
Pick: StripeStripe for payments, GitHub for code, Slack for alerts. Connect the tools you already own to Squiid and let every agent use them with one key.
Use Squiid with your agent
Where each coding agent reads environment variables and project rules, and how to give it one key instead of twelve.
Claude Code
Setup guideClaude Code is Anthropic terminal coding agent. Give it one Squiid key in .env and it can reach Supabase, Vercel, Resend and 105 more services.
Cursor
Setup guideCursor is an AI-first code editor with an agent mode. One Squiid key in .env lets it use Supabase, Vercel, Resend and 105 more services.
ChatGPT
Setup guideChatGPT writes a lot of app code but does not run in your repo. Keep one Squiid key in .env so no provider secret ever enters a chat.
Codex
Setup guideCodex is OpenAI software engineering agent, in the terminal, the IDE and the cloud. One Squiid key gives it every service your project needs.
Grok
Setup guideGrok is xAI assistant and coding model family. Use one Squiid key so the code it writes never needs a provider secret in the prompt.
Gemini CLI
Setup guideGemini CLI is Google open-source terminal agent. One Squiid key in .env gives it Supabase, Vercel, Resend and 105 more services.
GitHub Copilot
Setup guideGitHub Copilot completes code, answers in chat and now works issues as an agent. Give it one Squiid key instead of a folder of provider secrets.
Windsurf
Setup guideWindsurf is an agentic IDE with the Cascade agent. One Squiid key in .env lets Cascade use every service your project needs.
Perplexity
Setup guidePerplexity answers with citations and ships a Sonar search API. Use it to choose a stack, then run that stack on one Squiid key.
Devin
Setup guideDevin is an autonomous software engineer working in its own cloud workspace. Give it one Squiid secret instead of a dozen provider keys.
Replit
Setup guideReplit Agent builds and hosts apps in the browser. Put one Squiid key in Replit Secrets and it can use every service your project needs.
v0
Setup guidev0 by Vercel generates React and Next.js interfaces you can deploy in a click. One Squiid key connects the generated app to real services.
Lovable
Setup guideLovable builds full-stack apps from a prompt in the browser. Use one Squiid key so the generated app reaches real services safely.
Cline
Setup guideCline is an open-source autonomous coding agent for VS Code. One Squiid key in .env gives it every service your project needs.
Comparisons
Honest comparisons against the alternatives, including the cases where the alternative wins.
All comparisons
ComparisonSquiid against gateways, secret managers, integration platforms, platform bundles and doing it yourself.
Squiid vs OpenRouter
ComparisonCheaper for pure inference and better at routing. Squiid covers the other fifteen categories.
LLM gateways compared
ComparisonOpenRouter, Inworld, Vercel, Cloudflare, Portkey, LiteLLM and Helicone, side by side.
Squiid vs signing up directly
ComparisonFree and unambiguously yours. Also one account, one key and one invoice per service.
Squiid vs secret managers
ComparisonThey organise the keys you have. Squiid means most of those keys never reach you.
Integration platforms compared
ComparisonComposio, Nango, Merge, Zapier, Pipedream and RapidAPI, and where procurement actually sits.
Docs
The gateway convention, spend controls, handover and a five minute quickstart.
Quickstart
DocsGo from nothing to a working service call in five minutes: create an account, add a service, copy your key, set one env var, point your agent at it.
The gateway convention
DocsEvery Squiid service is reached the same way: https://api.squiid.io/v1/<service>/ with Authorization: Bearer $SQUIID_API_KEY. One rule for every service.
Spend controls
DocsPrepaid credits, alerts at 75/90/100%, pause on zero and capped auto top-up. How Squiid stops a runaway agent from becoming an invoice.
Handover
DocsTransfer where the provider supports it, export everywhere else. What leaving looks like for each provider.
