Firestore

Easily develop rich applications using a fully managed, scalable, and serverless document database.

TmpState (temp state) - a tokenless temporary JSON database. One curl creates a database; the URL is the only credential. No signup, no API keys, 24h free, $1 to keep for a week. Also a zero-key MCP server: https://tmpstate.dev/mcp

Firestore features and specs

Scalability
Google Cloud Datastore can automatically scale to handle large amounts of data and high read/write loads, making it suitable for applications with growing data needs.
Fully Managed
As a fully managed service, Google Cloud Datastore eliminates the need for managing servers, software patches, and replication, allowing developers to focus on building applications.
High Availability
Datastore provides strong consistency for reads and writes and is designed to maintain availability even in case of entire data center outages.
Flexible Data Model
The schemaless nature of Datastore allows for a flexible data model that can easily adapt to changes in application requirements.
Integration with Google Cloud Platform
Datastore seamlessly integrates with other Google Cloud Platform services, which simplifies the process of building end-to-end solutions.

Possible disadvantages of Firestore

Complex Query Language
Datastore Query Language (GQL) can be less intuitive compared to SQL, which may pose a learning curve for developers accustomed to traditional relational databases.
Eventual Consistency for Queries
While Datastore offers strong consistency for entity lookups by key, queries must be specifically configured for strong consistency, otherwise they might return eventually consistent data.
Cost
As usage scales, costs can increase, particularly for applications with high write loads or those requiring many transactional operations, which might be a consideration for budget-conscious projects.
Limited Relational Capabilities
Datastore is a NoSQL database, which means it lacks some of the relational features like joins and complex transactions that developers might expect from a SQL database.
Index Management
Managing indexes can become complex, as every query in Datastore requires a corresponding index, and poorly planned indexes can lead to increased storage costs and slower query performance.

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 Firestore 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.

Using Google Cloud Firestore with Django's ORM
A long time ago, a fork of Django called “Django-nonrel” experimented with the idea of using Django’s ORM with a non-relational database; what was then called the App Engine Datastore, but is now known as Google Cloud Datastore (or technically, Google Cloud Firestore in Datastore Mode). Since then a more recent project called "django-gcloud-connectors" has been developed by Potato to allow seamless ORM integration... - Source: dev.to / over 2 years ago
