On October 2, 2026, Supabase raised $150M and agreed to buy Turso. Pick **Supabase** for a full backend, **Neon** for Postgres that scales to zero, and **Turso** for thousands of tiny SQLite databases where an idle one costs only storage. Nothing changes for Turso users yet. 13 min read3 databases comparedPublished October 19, 2026 ## Key takeaways * Supabase announced $150M in funding and an agreement to acquire Turso on October 2, 2026; the price was not disclosed. * Nothing changes for Turso users yet: databases, APIs and workflows keep running, and Turso Database stays open source. * Supabase says about 70% of its new databases are created by AI agents or AI-driven tools, and it adds over 4 million databases a month. * For thousands of small, mostly idle databases, Turso is cheapest: idle databases cost only storage, and Developer is $4.99 a month for unlimited databases. * Neon (part of Databricks) scales Postgres to zero after 5 minutes idle; Supabase Pro is $25 a month and bundles auth, storage and realtime. ## Why do AI agents need a database each? The way databases get created has flipped. Supabase says about 70% of its new databases are now created by agents or AI-driven tools, and that it adds more than 4 million databases a month. AI app builders spin up a backend for every generated app; coding agents create sandboxes to test against; products give every user or every task an isolated store. That changes what a database has to be good at. Raw performance matters less than how fast a new one starts, how little an idle one costs, and how cleanly it can be thrown away. The three here answer that differently. ### Isolation by default One database per agent, user or task means one cannot read or corrupt another's data, with no row-level rules to get wrong. ### Cleanup is one delete When the experiment, preview or task ends, the whole database goes with it — no orphaned rows to hunt down. ### Idle has to be nearly free Most of these databases sit unused most of the time. A model that bills always-on compute per database does not survive contact with thousands of them. ### A path to grow up The one experiment that turns into a product needs real Postgres, backups and a team around it, without a rewrite. **The honest limit:** thousands of databases are thousands of schemas to migrate, back up and monitor. Many products are better served by one database with good row-level security. Database-per-agent pays off when isolation or cleanup is the hard problem, not by default. **Do you need this yet?** If you are building one SaaS app, no — pick a database for the app and skip the per-agent question. It matters if you build an AI app builder, a coding agent, a multi-tenant product with strict isolation, or anything that creates databases from code. ## Quick Verdict ![](https://appstackbuilder.com/supabase.svg)Supabase Postgres plus auth, storage, realtime and edge functions in one project.

Embedded replicas and sync for local-first apps. Joining Supabase. 100 DBs freeSQLite, not Postgres TL;DR No single winner — pick on the shape of your data. One app that needs auth, storage and a database → **Supabase**. Postgres per user, per preview or per branch, idle most of the time → **Neon**. Thousands of tiny databases, one per agent or task, or local-first sync → **Turso**. ## What does the Supabase–Turso deal change? Less than the headlines suggest, for now. Here is what each company has actually said, and what is still open. ### Stated * Turso "keeps running"; databases, APIs and workflows continue as they do today. * Turso Database stays open source and under active development. * A path from SQLite to standard Postgres through Supabase, and later Multigres for very large scale. * Glauber Costa becomes Supabase's Head of Agentic Services; Pekka Enberg and the team join too. * Deeper integration "in the coming months". ### Not yet stated * The purchase price and a closing date. * Whether Turso's pricing or plans will change, and when. * How Turso will be packaged inside the Supabase dashboard and billing. * The long-term role of libSQL, the earlier MIT-licensed fork, now that development centres on Turso Database. If you run Turso in production today, there is nothing to migrate. Keep your exports current, pin the client library versions you test against, and read the integration announcements as they land. ## How do Supabase, Neon and Turso compare on price? Plans and list prices as published on each vendor's pricing page in October 2026. Auth, storage, realtime included ![](https://appstackbuilder.com/supabase.svg) ### Supabase Postgres plus a whole backend $0 Free · $25/mo Pro Team from $599/mo; Enterprise custom * Free: 2 active projects, 500 MB database, 50,000 MAU * Free projects pause after 1 week of inactivity * Pro: 8 GB disk per project, 100,000 MAU, 250 GB egress * Pro includes $10/month compute credit (one Micro instance) * Overage: $0.125/GB storage, $0.09/GB egress, $0.00325/MAU * Branching, edge functions and file storage built in * CaveatEach project has its own always-on compute, so a project per agent gets expensive fast. For many tenants, use one project with row-level security, or watch for the Turso-based agent services Supabase is building. Best for: Apps that need a database, auth, file storage and realtime from one vendor. Scales to zero after 5 min ![](https://appstackbuilder.com/neon.svg) ### Neon Serverless Postgres, from Databricks $0 Free · usage-based paid Launch $0.106/CU-hour; Scale $0.222/CU-hour * Free: 100 projects, 100 CU-hours and 1 GB per project, 20 GB total * Paid storage $0.35/GB-month, unlimited * Launch: 100 projects, 10 branches each, autoscale to 16 CU * Scale: 1,000 projects, 25 branches each, up to 56 CU fixed * Extra branches $1.50 per branch-month * No monthly minimum; billed hourly * CaveatProject and branch limits cap how many databases you can hand out: 100 projects on Launch, 1,000 on Scale. Past that, the per-branch fee adds up, and Scale's compute rate is double Launch's. Best for: Postgres per user, per preview deployment or per agent session, where most sit idle. Idle databases cost only storage ![](https://www.google.com/s2/favicons?domain=turso.tech&sz=128) ### Turso SQLite by the thousand $0 Free · $4.99/mo Developer Scaler $24.92/mo; Pro $416.58/mo * Free: 100 databases, 5 GB, 500M rows read, 10M written * Developer: unlimited databases, 9 GB, 2.5B rows read * Scaler: 24 GB, 100B rows read, 100M written * Overage from $0.75/GB storage, $1 per billion rows read * Point-in-time restore and branching at no usage cost * Runs in Turso Cloud or your own cloud (BYOC) * CaveatIt is SQLite, not Postgres: different SQL dialect, extensions and tooling. Fine for per-agent state and local-first apps; plan the path to Postgres if one of those databases becomes your product. Best for: Thousands of small, isolated databases — one per agent, task or user — and offline-first sync. ## What do 1,000 agent databases cost? Two workloads, list prices from October 2026\. Your numbers will differ; the shape usually does not. | Workload | Supabase | Neon | Turso | | --------------------------------------------------------------- | ----------------------------------------------------------- | -------------------------------------------------- | -------------------------------------------------- | | One SaaS app: 5 GB, steady traffic | \~$25 (Pro, includes auth and storage) | \~$15–21 (Launch: 0.25–0.5 CU plus $1.75 storage) | $4.99 (Developer, inside 9 GB) | | 1,000 agent databases, 10 MB each, each active \~1 hour a month | Not the model — one project with row-level security instead | \~$60 (Scale: 1,000 projects, 250 CU-hours, 10 GB) | $4.99 (Developer: unlimited databases, 10 GB fits) | **These are not like-for-like:** Supabase's $25 buys a whole backend, not just a database. Neon and Turso are databases only; add auth and file storage elsewhere. And Turso is cheapest partly because it is SQLite — if your agents need Postgres features, the comparison is Supabase versus Neon. ## Feature comparison Capability ![](https://appstackbuilder.com/supabase.svg)Supabase ![](https://appstackbuilder.com/neon.svg)Neon ![](https://www.google.com/s2/favicons?domain=turso.tech&sz=128)Turso Engine Postgres Postgres SQLite Databases on free plan 2 projects 100 projects 100 Idle cost Always-on compute Storage only Storage only Branching ✓ ✓ ✓ Auth and file storage built in ✓ ✗ ✗ Local-first sync ✗ ✗ ✓ Cheapest paid plan $25/mo Usage only $4.99/mo Owner Independent Databricks Joining Supabase ## Challengers worth knowing ![](https://appstackbuilder.com/cloudflare.svg)Cloudflare D1 and Durable Objects SQLite databases that live next to Workers code, with Durable Objects giving each object its own SQLite store.

On October 2, 2026 Supabase announced $150 million in new funding led by GIC and an agreement to acquire Turso, the SQLite-based database company. The price was not disclosed. Turso founder Glauber Costa joins Supabase as Head of Agentic Services, along with co-founder Pekka Enberg and the Turso team. ### What happens to Turso users after the Supabase acquisition? For now, nothing. Turso says its platform keeps running and that existing databases, APIs and workflows continue as they do today, and that Turso Database stays open source and under active development. Both companies say deeper integration with Supabase will come in the coming months, including a path to standard Postgres for apps that outgrow SQLite. No pricing changes have been announced. ### Supabase vs Neon vs Turso: which is best for AI agents? There is no single best one; they suit different agent workloads. Supabase is a full backend (Postgres, auth, storage, realtime) and is where many AI app builders create projects. Neon is serverless Postgres that scales to zero after five minutes idle and branches instantly, which suits a database per user or per preview. Turso runs SQLite databases where an idle database costs only its storage, which suits thousands of tiny databases, one per agent or task. ### Who owns Neon? Neon is part of Databricks; its site describes it as coming "from Databricks". The serverless Postgres service, its free plan and its usage-based Launch and Scale plans continue under that ownership. ### Is Turso Postgres? No. Turso is built on SQLite: first libSQL, an open-source fork, and now Turso Database, a rewrite of SQLite. It speaks SQLite’s SQL dialect, not Postgres’s. That is why the Supabase deal emphasises a path to Postgres for apps that outgrow a lightweight database. ### Which is cheapest: Supabase, Neon or Turso? For many small or idle databases, Turso: the free plan includes 100 databases and 5 GB, and Developer at $4.99 a month allows unlimited databases with 9 GB. For one app database, Neon’s usage-based Launch plan can cost less than Supabase Pro at low traffic because compute scales to zero, while Supabase Pro at $25 a month includes auth, storage and realtime that you would otherwise pay for separately. ### Why do AI agents need their own databases? Agents and AI app builders create apps, sandboxes and experiments on demand, and each one needs somewhere isolated to keep state. Giving each its own database avoids one agent reading or corrupting another’s data and makes cleanup a single delete. That only works if idle databases are nearly free, which is why scale-to-zero and per-database cost now matter as much as raw performance. Supabase says about 70% of its new databases are created by agents or AI-driven tools. ## Sources Prices and plan limits were read from each vendor's pricing page on October 19, 2026. * [Supabase: $150M in new funding and Turso acquisition (press release, Oct 2, 2026)](https://www.prnewswire.com/news-releases/supabase-announces-150m-in-new-funding-and-turso-acquisition-302896752.html) * [Turso: Turso is joining Supabase](https://turso.tech/blog/turso-is-joining-supabase) * [SiliconANGLE: Supabase raises $150M and buys Turso](https://siliconangle.com/?p=849239) * [Supabase pricing](https://supabase.com/pricing) * [Neon pricing](https://neon.com/pricing) * [Turso pricing](https://turso.tech/pricing) ### Related Articles [Neon vs Supabase vs PlanetScalePostgres for a classic SaaS app](https://appstackbuilder.com/blog/neon-vs-supabase-vs-planetscale-2026)[Supabase vs FirebaseThe backend-as-a-service decision](https://appstackbuilder.com/blog/supabase-vs-firebase-for-startups)[Best AI Agent MemoryWhat agents remember between runs](https://appstackbuilder.com/blog/best-ai-agent-memory-2026) ### Explore More [All Blog Posts](https://appstackbuilder.com/blog)[Database Tools](https://appstackbuilder.com/categories/database)[Neon vs Turso](https://appstackbuilder.com/compare/neon-vs-turso)[Stack Generator](https://appstackbuilder.com/build-stack)
