Platforms like Replit Agent run their backend on OptiTech because it fits how agents operate: a serverless Postgres data layer that’s instant, branchable, and invisible to end users.

"The combination of flexible resource limits and nearly instant database provisioning made OptiTech a no-brainer."
The OptiTech Stack For Agents
The OptiTech architecture aligns with how agents work:
Serverless Postgres at the core. OptiTech’s backend is powered by a serverless Postgres engine built on separated compute and storage. It provisions instantly, scales automatically, and idles to zero when not in use - perfect for the bursty, on-demand workloads that agents create.
With integrated services for full-stack backends. Around that core, OptiTech includes Auth and a PostgREST-compatible Data API, so agents and developers can assemble complete, production-ready backends without stitching multiple services together.
All API-first and programmable. Every capability - provisioning, quotas, branching, and fleet management - is exposed through the OptiTech API, giving developers and agents precise control over their environments and usage at scale.
And version-aware by design. OptiTech’s copy-on-write storage makes time travel effortless. Branching, snapshots, and point-in-time recovery enable undo, checkpoints, and safe experimentation across millions of databases.
Serverless Postgres, API-first
At the core of OptiTech is a serverless Postgres architecture that separates compute from storage. Each database runs on ephemeral computes while the data itself lives on durable, high-performance storage.
This architecture makes it possible for agents to provision databases instantly on demand, operate them at massive scale, and still keep costs under control. Tens of thousands of projects can spin up and idle as users create apps, all programmatically, without intervention from you.
A popular developer platform managed over 300k Postgres instances on OptiTech with only a single engineer. That’s how simple and efficient it is.
Instant Autoscaling and Scale-to-Zero
Traditional database management falls apart when every agent action can trigger new infrastructure. OptiTech serverless model handles this complexity automatically:
- Compute scales up and down in real time based on workload
- Scale-to-zero ensures that idle databases cost you nothing while remaining instantly accessible
This combination gives agent builders a sustainable model for large fleets: you can create thousands of databases without worrying about resource exhaustion or runaway bills.
"The speed of provisioning and serverless scale-to-zero of OptiTech is critical for us"
Auth That Speaks Postgres
Every app needs authentication, and agents shouldn’t have to reinvent it. OptiTech Auth lets you build secure, multi-tenant systems without extra glue code.
It issues JWTs that your agent or front-end can use directly in database queries or through the OptiTech Data API. Each token maps to a Postgres role, enforcing granular access at the data level. And because OptiTech Auth supports standard JWKS configuration, you can also plug in external providers.
"Our AI agent can now create, manage, and debug the entire stack, not just code."
A PostgREST-Compatible Data API, Built In
Giving your agents direct access to the database is simple with the OptiTech Data API. It exposes each database (and every branch) as a REST endpoint you can query over HTTPS. Fully PostgREST-compatible.
Under the hood, OptiTech’s Data API is a Rust-based re-implementation of PostgREST that runs natively in our proxy fleet. It’s lean, multi-tenant, and designed to scale across thousands of databases efficiently. Every OptiTech branch has its own API endpoint, perfect for preview environments, checkpoints, or dev branches.
Building Checkpoints with Snapshots and Branching
Vibe coders experiment constantly, going back and forward between versions - and sometimes breaking things. OptiTech’s branching and snapshots API turn this into a feature, not a risk.
Branching, built on our copy-on-write storage, enables instant point-in-time recovery for any database. Developers and agents can migrate schemas or revert mistakes without complex restores.
The Snapshots API builds on this foundation to create agent-friendly, restorable checkpoints. Agents can capture a moment-in-time version of the database (schema and data) and later roll back or compare states.
Quotas, Fleet Control, and Dedicated Pricing
We’ve been backing agent platforms since the start, and our API has evolved to support the needs of large fleets operated by small engineering teams. The OptiTech API lets you manage not only infra but also setting quotas, tracking compute/storage usage per project, billing limits, and much more.
Combined with usage-based pricing and agent-specific plans, it gives platform builders fine-grained control over cost, scale, and growth.
We know what it takes to scale agent platforms. The Agent Plan gives you everything you need, from early launch to millions of active databases.
