Introducing Agentic Postgres Free Plan: The Fastest Way to Experiment with AI on Postgres

TLDR: A new chapter for Postgres starts today: Agentic Postgres, the first database for agents, brings new architecture for the age of agents, and free access for everyone who builds with them.

We're launching a free tier. No credit card, no time limit, no catch.

AI development moves at the speed of thought. You’re constantly experimenting, testing a vector search strategy, forking a database to try a new schema, or spinning up an instance for a weekend project. The friction of “will this cost me money?” shouldn’t slow you down.

Today, we’re launching the Tiger Free Plan, a fully managed Postgres built for how AI development actually works: experimental, iterative, and increasingly agent-driven. It’s the same Tiger managed cloud experience developers already love, now free for every idea.

The Tiger Free Plan should be the database you reach for every time you want to test an idea. 

What Makes This Free Plan Different

Most free database tiers are built for yesterday’s users. They gate core features, expire trials, or remind you what you don’t get. We built ours for how development actually happens today.

Because the database has a new user. Developers aren’t working alone anymore. They’re building alongside agents that write code, run migrations, and query data through APIs. That changes what experimentation means. You don’t just need a place to store data, you need a system where your tools, scripts, and agents can spin up, fork, and reason over automatically.

The Tiger Cloud Free Plan is built for that reality. It’s not designed for production. It's designed for progress, for the 90 percent of work that happens before you know if something is worth scaling.

Other free tiers optimize for control. Ours optimizes for momentum. When you’re experimenting, you shouldn’t have to think about limits, billing, or setup. You should be able to fork your database, test a schema, or try a new retrieval strategy in seconds, whether you’re doing it yourself or your agent is doing it for you.

That’s why it includes the tools modern AI workflows actually rely on. You can fork your database to test safely and recover fast, run vector search to compare retrieval and embedding strategies in real time, and analyze live data with built-in time-series and columnar features so you can see what’s happening as it happens. Because Tiger Cloud runs the same APIs across every plan, moving from free to production is instant: no migration, no rework, no context lost.

This isn’t a teaser or a trial. It's part of a new architecture for Postgres, one built for builders: humans and agents alike. 

What’s Included

Compute & storage:

• Shared compute
• Up to 750 MB of storage per service
• Limit of 2 free services per account
• Available in us-east-1 (EU expansion coming soon)

Features that matter:

• Database forks: Branch your database like your code. Test safely, recover fast, or try something bold.
• AI-native retrieval: Build RAG and other AI-powered features with native hybrid and vector search support (pgvectorscale + BM25).
• Real-time analytics: Hypertables, continuous aggregates, and columnar storage. Run analytics in Postgres without extra systems.
• Insights: View performance on a per-query basis over time, and get optimization recommendations, so you spend less time guessing. 
• Automated Management: Upgrades, tuning, and maintenance handled for you, so your database always runs at its best.
• 50+ Postgres Extensions. All your favorite extensions, from PostGIS to pgvector, built in and ready to go.
• Connection management: Simplified, secure handling that just works.

What Happens When You Hit the Limits

At 750 MB, your service switches to read-only mode. You’ll get warnings as you approach the limit, and you can:

• Fork to an earlier point in time (PITR - 24-hour point in time recovery)
• Clean up data
• Or upgrade to a paid plan and migrate in minutes

Free services can be upgraded directly. When your project grows, you can quickly convert it in place to remove storage limits. Your free services coexist perfectly with your paid ones, so you can test safely alongside production.

Connection poolers are not included in the Free Plan. Dedicated support is not included either, but Free Plan users are encouraged to join our community Slack to ask questions, share ideas, and see what others are building.

Built for the builders: Developers and agents alike

If you're new to Tiger, you can start with the free plan or take a 30-day performance trial. If you're already a customer, you can add two free services right inside your existing account for testing, sandboxing, or side projects.

The Free Plan is our way of lowering the floor for experimentation. We want more developers and agents building together on postgres without friction. It's a small change with a big goal: making it effortless to start, learn, and build.

   1. Connection pooler
   2. Compute resizing
   3. Dedicated support (community Slack available)
   4. High-availability configurations
   5. Advanced security features
   6. Advanced enterprise features
3. What are the specs of a free service?
   1. Each free service includes:
      1. Shared compute
      2. Storage: Up to 750 MB for user data
      3. Backup: 24-hour point-in-time recovery for forking

6. Can I upgrade free services?
   1. Yes. If your project outgrows the Free Plan, you can:
      1. Switch to a Performance or Scale plan
      2. Convert your free service to a standard service to remove storage limitations and get access to higher levels of compute
7. What is the difference between Free Plan and Performance Plan?
   1. Performance Plan offers:
      1. Scalable compute (starting at 0.5 CPU / 2 GB RAM, up to 16 CPU / 128 GB RAM)
