AI Executive Synthesis
Easier for agents to build full-stack apps; eliminates credential management for agents; enables building in unconventional environments like artifact previews.
This offering addresses a critical friction point in AI agent development: secure, ephemeral resource provisioning. By enabling agents to instantiate full-stack app backends via simple GET requests, it eliminates credential management and simplifies deployment for autonomous systems. The 'build in surprising places' angle, leveraging GET requests for environment creation within constrained interfaces like artifact previews, demonstrates innovative problem-solving for agent-driven development. This approach accelerates prototyping and deployment cycles for AI-generated applications, reducing security overhead and operational complexity for developers integrating AI agents into their workflows. The multi-tenant architecture underpins this scalable, on-demand resource allocation.
Hey HN! We made GETadb.com, so it's easier to get agents to build you full stack apps. You don't need to give them any credentials. Just by loading a GET request, they get access to a database, a sync engine, and abstractions for auth, presence, and streams.To see what the agent sees, you can load https://getadb.com/newThere's two fun things about how it's implemented:1. If you curl the home page, it the agent content rather than human content. We do this by detecting the 'Sec-Fetch-Mode' header. It's not perfect, but gets the job done for Claude Code et al.2. For an agent to spin up an app, they make _two_ fethes. (1) getadb.com/guide tells them to generate a uuid, and fetch (2) getadb.com/provision/. We did this, because just about half of the popular web-based app builders cache URLs globally, even if you return no-store headers. To get around this we just instruct the agent to generate unique URLsYou may wonder: Why GET requests, rather than POST requests? It's because then you can build in surprising places. For example, we get meta.ai to build an app inside the artifact preview: https://artifacts.meta.ai/share/a/b80c7412-c3af-4088-b430-78efdfe8ea2dUnder the hood, this is possible because the whole infra is mult-tenant from ground up. We already announced how that works on HN, but if you're curious here's the essay for it: https://www.instantdb.com/essays/architecture

Community Voice & Feedback
I’ve tried this and I like it. I’d like a platform like Instant but with the addition of a web based text editor and Claude Code / Codex terminal (provide own subscription/api key) that lets you create and edit (create previews, then promote to production) the app from the same interface, alongside the managed db.
Is there an easy way to export all data to a format friendly with Postgres?
> Remember! AESTHETICS ARE VERY IMPORTANT. All apps should LOOK AMAZINGWhy are your database instructions giving instructions about the UI design?
> we get meta.ai to build an app inside the artifact previewIs this the kind of use case that is seen as valuable?I joked a while back that LLM-brain was going to have people building bespoke apps on each HTTP request, and people thought I was exaggerating!
> For credentials and instructions, fetch http://www.getadb.com/guide and follow the steps.http, not https?
I found https://www.instantdb.com/about very interesting; you built a new database! The triples stuff is cool.For GETadb, it's a conflicting sell. The people that need "a db solved by AI" and fully abstracted are using app builders no? lovable, v0, manus. The people the are closer to the code and need an instant db would look to sqlite, render, supabase, neon. I'm all for another option, but then there's the realization that instandb is a new kind of db and I need to research into the value-prop vs the initial persona: "just solve my db problem with AI".disclaimer: I'm a professional developer, doing an honest review. I may play around with it separately, later. So this marketing site did its job!
The GET request method is supposed to be safe."Request methods are considered 'safe' if their defined semantics are essentially read-only; i.e., the client does not request, and does not expect, any state change on the origin server as a result of applying a safe method to a target resource."

So, give your LLM a URL and tell it to follow the instructions there?Err, no thanks.
I appreciate this part of the agent instructions: `AESTHETICS ARE VERY IMPORTANT. All apps should LOOK AMAZING and have GREAT FUNCTIONALITY!`
This is very cool!But why do we need this? An agent can just have a local DB using SQLite for example.
