Supabase features and specs

  • Real-time capabilities
    Supabase offers real-time database features that allow you to subscribe to database changes and sync data with your frontend seamlessly.
  • PostgreSQL foundation
    Supabase is built on PostgreSQL, a robust, mature, and highly extensible SQL database, providing strong data integrity and reliability.
  • Open-source
    Supabase is open-source, which means you can inspect, modify, and contribute to the source code. This fosters community engagement and transparency.
  • Ease of use
    Supabase provides an intuitive dashboard and auto-generated APIs, making it easy for developers to manage databases without extensive backend knowledge.
  • Authentication and Authorization
    Supabase includes pre-built authentication and authorization modules, supporting various sign-in methods like email, OAuth, and more, simplifying user management.
  • Scalability
    Supabase is designed to scale with your application, offering plans that can handle from small to large-scale traffic and data operations.

Possible disadvantages of Supabase

  • New and evolving
    As a relatively new platform, Supabase is still evolving, which means it might lack some features found in more mature solutions and could have occasional bugs or stability issues.
  • Limited integration
    Currently, Supabase has fewer third-party integrations compared to other established backend-as-a-service (BaaS) providers, which might limit its utility in diverse tech stacks.
  • Learning curve
    Despite its user-friendly interface, there could be a learning curve for those unfamiliar with PostgreSQL or real-time database concepts.
  • Pricing for advanced features
    While Supabase offers a free tier, advanced features, and higher usage plans come with a cost. This might be limiting for startups or hobby projects with tight budgets.
  • Limited geographic presence
    Supabase's infrastructure might have limited geographic data centers compared to larger cloud providers, potentially affecting latency and performance for users in certain regions.

TmpState.dev features and specs

  • Simple Concept
    A service focused on temporary state storage suggests a lightweight, single-purpose tool that could be easy to integrate into development workflows without unnecessary complexity.
  • Useful for Prototyping
    Tools designed for temporary state management are often valuable for quick prototyping, testing, or short-lived data needs where a full database setup would be overkill.
  • Developer-Focused
    The '.dev' domain and naming convention suggest this is targeted specifically at developers, potentially offering a tailored experience with relevant features like API access or CLI tools.
  • Potentially Low Setup Overhead
    Temporary state services typically aim to minimize configuration, allowing developers to quickly store and retrieve data without extensive setup procedures.
  • Niche Utility
    By focusing on a specific use case (temporary state), the tool may excel at that particular function rather than trying to be an all-purpose solution.

Questions & Answers

As answered by people managing Supabase and TmpState.dev.

What makes your product unique?

TmpState.dev's answer:

TmpState is a tokenless temporary JSON database. One curl tmpstate.dev creates a real database and returns its URL - and that URL is the only credential. No signup, no API keys, no .env, no OAuth.

  • Zero credentials by design. The database URL is a capability (30+ characters of entropy, hashed at rest), the same trust model as an unguessable Google Docs share link. Nothing to provision, rotate, or leak into a repo.
  • Agent-native. It is also a zero-key remote MCP server, so an AI agent can create and use its own backend with no auth handshake - it self-onboards from llms.txt.
  • Ephemeral by default. Databases are free for 24 hours and expire automatically unless you keep them, so nothing lingers or bills silently.
  • Honest, transparent pricing. Free for 24h, one-time extensions from $1, always-on Pro at $8/month. Every charge is disclosed before it is billed.

Why should a person choose your product over its competitors?

TmpState.dev's answer:

Compared to jsonbin.io, npoint.io, json-server, or standing up Firebase/Supabase, TmpState removes the entire setup step:

  • No account and no keys - you get a working database from a single request, versus signing up and managing credentials elsewhere.
  • Faster to first write - one curl, not a dashboard, a project, and a connection string.
  • Built for agents - a native MCP server means your AI agent wires up its own storage instead of you pasting secrets into it.
  • Safe to abandon - deletion by default means no orphaned data or surprise bills; you only pay ($1 extension or $8/month Pro) when the data actually matters.

Best for throwaway and prototype state. It is honest about when not to use it: it is not meant to be your permanent production database.

How would you describe the primary audience of your product?

TmpState.dev's answer:

Developers and the AI agents working on their behalf. Primarily:

  • Builders using AI coding agents (Claude Code, Cursor, and similar) who want their agent to provision its own backend.
  • Indie hackers and solo builders prototyping quickly across several projects.
  • Hackathon participants who need a backend in the next ten minutes and will not sign up for anything.
  • Anyone who needs disposable, short-lived JSON storage without the ceremony of a full database.

What's the story behind your product?

TmpState.dev's answer:

TmpState came out of a recurring frustration in agent workflows: AI agents constantly need somewhere to keep state, but you cannot hand them your real cloud credentials, and wiring up a database mid-task kills the flow. So the model was inverted - build a database where the URL itself is the only credential, so an agent (or a person with one curl) can create its own backend instantly, with nothing to sign up for and nothing to leak. It is a solo, founder-built, agent-first product, launched in July 2026.

  • Opus vs GPT on Real Ops, Part 2: One Drove, One Was Driven
    Opus, zero nudges.
