Xata Overview

Xata is a serverless Postgres platform that adds developer experience features on top of vanilla Postgres. It went through a significant repositioning in 2025, and the product you sign up for today leads with copy-on-write database branching (like Git branches for your schema and data), scale-to-zero compute, and built-in data anonymization for safe development branches. The core platform is now open source, which is a real change from the earlier hosted-only product.

The pitch is "one Postgres, thousands of branches." You get a real Postgres database underneath, but the workflow is built around spinning up an isolated branch for every pull request or every agent, with the data masked so you can develop against production-shaped data without exposing it. That branching model is genuinely useful when you're iterating fast on schema.

Pricing moved to pay-as-you-go. The headline Xata Cloud rate is $0.012 per compute hour plus $0.28 per GB per month of storage, with scale-to-zero so an idle branch stops billing compute. There is also an Open Source plan that is free forever (you run it yourself) and a BYOC tier for teams that want it in their own cloud. Earlier versions of Xata advertised a flat $20 per month Pro plan and a 15 GB free tier with bundled Elasticsearch search; the current pricing page no longer lists that flat Pro plan, so check current pricing before you budget around an old number you may have seen.

Supabase Overview

Supabase is the broader open source Firebase alternative built on Postgres. It gives you a Postgres database, GoTrue authentication, S3-compatible storage, realtime subscriptions, edge functions in Deno, and an auto-generated REST and GraphQL API via PostgREST. Vector search via pgvector is built in.

The hosted product has a generous free tier and the Pro plan is $25 per month. Self-hosting is supported but it's a multi-service Docker Compose deployment that takes real ops work to run well. Most solo developers stick with hosted.

Supabase has become the default Postgres-based platform for serious indie projects. The Row Level Security model is the killer feature once you internalize it. You can build full multi-tenant apps with permissions enforced at the database level, which is hard to replicate elsewhere without a lot of custom code.

Key Differences

Scope of platform is fundamentally different. Xata is a database platform with some extras (search, branching, file attachments). Supabase is a complete backend platform (database, auth, storage, realtime, functions). If you only need a database and you have auth solved elsewhere, Xata's narrower focus is cleaner. If you want one vendor for everything, Supabase covers more ground.

Branching is Xata's standout feature. Database branches per pull request, with full schema and data isolation, is something Supabase only added more recently and still feels less polished. For solo developers who iterate on schema constantly, Xata's branching workflow is a real productivity win. Supabase branches exist but the experience is rougher.

Auth is bundled in one and not in the other. Supabase ships GoTrue with email auth, OAuth, magic links, and JWT token issuance built in. Xata expects you to use Clerk, Auth.js, or roll your own. For a solo developer who wants one less thing to set up, Supabase wins on convenience. For someone who already has an auth provider they like, Xata's lack of auth doesn't matter.

Search and file handling differ in approach. Xata bundles Elasticsearch-powered full-text search and file attachments directly into the row model. Supabase relies on Postgres full-text search (which is good but not Elasticsearch) and a separate S3-compatible storage service for files. For content-heavy apps where search matters a lot, Xata's built-in search is more capable out of the box.

Self-hosting is now possible on both. This used to be a clear split where only Supabase could be self-hosted, but Xata open-sourced its platform in 2025 and now ships an Open Source plan that is free forever to run yourself, alongside the supporting tools pgroll for zero-downtime migrations (6,481 GitHub stars) and pgstream for change capture (1,124 stars). Supabase remains open source and self-hostable through a multi-service Docker Compose deployment. Both are real undertakings to operate. The practical difference for a solo developer is maturity and community size: Supabase has 103,192 stars on its main repo, while the open-source Xata engine repo sits at 858, so you will find far more self-host guides and answers for Supabase.

By the Numbers (2026)

Checked on 2026-05-29 against vendor pricing pages, the npm registry, and the GitHub API.

Adoption and momentum. Supabase is the far larger project. The main supabase/supabase repository has 103,192 GitHub stars, and the JavaScript client @supabase/supabase-js (latest 2.106.2) pulled 19,829,221 downloads in the week of May 22 to 28, 2026. Xata is much smaller. The open-source xataio/xata engine repo has 858 stars, and the @xata.io/client SDK (latest 0.30.1) saw 111,695 downloads that same week, roughly 0.6 percent of Supabase's volume. Worth noting for anyone evaluating Xata's TypeScript SDK: the original xataio/client-ts repository is now archived on GitHub, which fits the platform's 2025 repositioning toward the Postgres wire protocol.

Supabase plan limits. The Free plan is $0 and includes 500 MB database, 50,000 monthly active users, 1 GB file storage, 5 GB egress, and 500,000 edge function invocations. Free projects pause after seven days with no database activity and you can run two free projects at once. The Pro plan is $25 per month and includes 8 GB database (then $0.125/GB), 100,000 monthly active users (then $0.00325 each), 100 GB file storage (then $0.0213/GB), 250 GB egress (then $0.09/GB), and 2 million edge function invocations (then $2 per million). Pro also bundles $10 per month in compute credits, which covers one Micro instance (2-core ARM, 1 GB RAM), and the spend cap is on by default so you do not get a surprise bill unless you turn it off. The Team plan is $599 per month with the same usage allotments plus added support and compliance.

Xata plan rates. Xata moved to pay-as-you-go. Xata Cloud is billed at $0.012 per compute hour plus $0.28 per GB per month of storage, with scale-to-zero so idle branches stop accruing compute. The Open Source plan is free forever if you self-host. BYOC is custom, with instance rates the page lists from $0.012/hr for a micro up to $1.536/hr for an 8xlarge. Xata does not publish a flat solo-tier monthly price the way Supabase does, so your bill depends entirely on how many hours your branches run and how much data you store.

Real Cost at Solo-Dev Scale

The two products bill on completely different shapes, so here is a concrete workload to compare them honestly. Assume a small live SaaS: one always-on production database holding 5 GB of data, a handful of users well under any free-tier user cap, light file storage, and modest traffic.

On Supabase, this is squarely a Pro plan, so the cost is the flat $25 per month. The 8 GB database allotment covers your 5 GB, the $10 compute credit covers the Micro instance, and with the spend cap on by default you stay at $25 unless you blow past the included egress (250 GB), users (100,000 MAU), or storage. For most solo projects, $25 is the whole bill and it stays predictable.

On Xata Cloud, you pay for compute hours plus storage. An always-on production database runs roughly 730 hours a month. At the published $0.012 per hour that is about $8.76 in compute, plus 5 GB of storage at $0.28 per GB which is $1.40, for a total near $10.16 per month at the Cloud rate. The catch is that this assumes a single always-on instance. Xata's model rewards the scale-to-zero pattern, so if your production database genuinely idles, your compute bill drops. But it also means that if you run several branches around the clock, each one bills like another instance and the total climbs past the Supabase flat fee quickly.

The honest read for a solo developer: at the low end with one always-on database, Xata Cloud can come out cheaper than Supabase Pro on raw database cost, roughly $10 versus $25. But that $25 on Supabase is also buying you auth, storage, realtime, and edge functions that you would otherwise wire up and pay for separately. If you only need the database and you keep one instance, Xata's per-unit pricing is attractive. If you want the bundled backend, Supabase's flat fee is doing more work for the money. Always confirm current pricing on each vendor's page before you commit, because both pricing models have changed in the last year.

When to Choose Xata

You want serverless Postgres with first-class TypeScript SDK
Database branching per pull request would change how you work
Built-in full-text search and file attachments matter to your app
You already have an auth solution and don't need one bundled
You like a tighter, narrower product instead of a sprawling platform

When to Choose Supabase

You want one platform for database, auth, storage, and realtime
You'll use Row Level Security for multi-tenant permissions
You want the option to self-host later
You need vector search via pgvector for AI features
You prefer a broader ecosystem with more community and templates

The Verdict

For most solo developers in 2026, Supabase is the better default. The combination of database, auth, and storage in one platform with a free tier that actually carries you to your first paying customers is hard to beat. The Row Level Security model is genuinely powerful once you get used to it, and the broader ecosystem means you'll find templates and answers for almost anything.

Xata is the right pick for specific cases. If you already use Clerk or Auth.js and don't want bundled auth, if database branching would meaningfully change your workflow, and if built-in search matters for your specific app, Xata is a sharper tool. The TypeScript SDK is also genuinely the best in this category.

The deciding factor is usually whether you want one vendor for everything or a focused database tool you'll combine with other best-in-class pieces. For most solo developers shipping their first or second product, one vendor wins on time saved. For solo developers with more established tooling preferences who just want a great Postgres platform, Xata earns its place.
