Upstash VS TmpState.dev

Upstash

Upstash provides Serverless Redis and Kafka as a service.

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

Upstash features and specs

Scalability
Upstash is a serverless database service that can automatically scale with your application's needs, ensuring high availability and performance without manual intervention.
Cost Efficiency
With a pay-per-request pricing model, Upstash can be cost-effective, especially for applications with variable workloads, since you only pay for what you use.
Ease of Use
Upstash simplifies database management with straightforward APIs and integration with popular platforms like AWS Lambda, making it easy to set up and use.
Low Latency
Being geographically distributed, Upstash offers low-latency access, which can improve the speed of data retrieval for end-users around the world.

Possible disadvantages of Upstash

Limited Database Options
Upstash currently focuses on a limited range of databases like Redis, which may not meet the needs of all projects requiring different types of databases.
Vendor Lock-in
Using a specialized platform like Upstash could lead to vendor lock-in, making it more challenging to migrate to other database providers or solutions in the future.
Feature Parity
Some advanced features found in fully-fledged, self-managed databases may not be supported by Upstash, potentially limiting functionality for complex applications.
Dependency on External Service
Reliance on an external service means that any downtime or service disruption on Upstash's part could directly impact your applications.

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 Upstash 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.
