T3 Stack vs Next.js SaaS Starters 2026

TL;DR: compare ownership, not “free versus paid”

Choose create-t3-app when you want a configurable application scaffold and are prepared to implement the product modules it does not claim to provide. Choose ShipFast or Supastarter only after the current edition's first-party feature matrix matches your required auth, billing, email, organization, admin, and deployment surfaces.

The purchase price is one input. The larger decision is ownership: which modules arrive implemented, which remain yours, what rights the license grants, and what the repository must change to meet the product backlog. This is a conditional comparison based on verified current features, current commercial terms, and measured implementation work.

Key Takeaways

create-t3-app is a configurable scaffold documented by the T3 project; it is not a complete SaaS product layer.
At access time, npm and GitHub latest release both identified create-t3-app 7.40.0. Before publication, recheck all three products.
ShipFast Starter $199 and Supastarter Solo $299 were the entry offers shown on 2026-08-23. Because promotions, plan scope, and terms change, recheck immediately before publication.
create-t3-app MIT evidence comes from its official registry and repository. Commercial starters remain governed by current commercial terms.
Public repository counters are omitted. They are a point-in-time repository signal, not comparable community, adoption, or quality evidence.
For implementation cost, estimate from your own scoped backlog. There is no reproducible comparison receipt for setup time, hours saved, dependency count, or year-one cost.

create-t3-app: a scaffold with explicit choices

The T3 documentation describes create-t3-app as a way to initialize an application with selectable technologies. Treat that as the product interface. Verify the current prompt and generated repository at version 7.40.0 rather than copying an old stack diagram.

For an evaluation, generate a disposable project and record:

selected technologies and package versions;
generated environment and database setup;
auth, API, ORM, and validation modules actually present;
missing billing, email, admin, organization, and deployment work from the product backlog;
the license of every added package or template.

The official registry and repository report create-t3-app MIT. That license does not describe third-party code added later.

ShipFast: evaluate the current edition

ShipFast's official product and documentation pages are the authority for what the currently sold edition includes. The checked page displayed ShipFast Starter $199, All-in $249, and a combined offer at $299 on 2026-08-23. Promotion and availability wording is volatile.

Do not infer a database, auth provider, API style, admin depth, or update right from an older article or code sample. Inspect the current page, checkout terms, documentation, and the purchased repository. Record each required product module as present, partial, absent, or unverified.

Supastarter: keep plan and edition scope explicit

Supastarter's checked page displayed Solo $299, Startup $799, and Agency $1,499 as one-time offers. Those plans have different scope. Verify project rights, seats, updates, refunds, frameworks, and included modules in the current terms before purchase.

Keep every integration claim edition-specific. A feature shown for one framework, plan, or release cannot be transferred to another. The same rule applies to auth, API, ORM, database, payment, email, admin, internationalization, and organization features.

Feature evidence table

Use this matrix as an audit template, not a claim that every row is already implemented:

Required surface	create-t3-app evidence	ShipFast evidence	Supastarter evidence
Framework and runtime	Current T3 docs and generated project	Exact current product page and repository	Exact current product page and repository
Authentication	Verify selected/generated package and app wiring	Verify provider, callbacks, recovery, and route protection	Verify provider, tenant context, recovery, and route protection
Billing	Add from the scoped backlog unless generated project proves otherwise	Verify checkout, webhook, reconciliation, and plan model	Verify checkout, webhook, reconciliation, and plan model
Organizations and roles	Product code unless generated project proves otherwise	Verify current edition	Verify current edition and plan scope
Email	Product code unless generated project proves otherwise	Verify provider, templates, and failure handling	Verify provider, templates, and failure handling
Admin and support tools	Product code unless generated project proves otherwise	Verify current edition	Verify current edition
Deployment	Test generated project against target	Test current repository against target	Test current repository against target

A first-party feature matrix should link every checked cell to the exact current product page, documentation page, or purchased source line. “Included” is not enough; record configuration, dependencies, and test coverage.

Pricing and license matrix

Values accessed 2026-08-23:

Product	Checked price signal	License or usage identity
create-t3-app	Open-source package; no purchase price	MIT in official npm and GitHub records
ShipFast	ShipFast Starter $199; All-in $249; combined offer $299	Current commercial terms govern use, projects, updates, and refunds
Supastarter	Solo $299; Startup $799; Agency $1,499	Current commercial terms govern plan and edition scope

Prices and plan names change. Recheck immediately before publication and again at checkout. Do not calculate a synthetic year-one total without the actual workload, labor assumptions, hosting plan, and purchased rights.

Maintenance and availability signals

The create-t3-app registry, repository, and latest-release endpoint, plus the ShipFast and Supastarter product and documentation pages, were reachable at access time. That is not a support or maintenance guarantee. Public tags and private product updates are different evidence types.

Use a maintenance record that distinguishes:

package version and release identity;
purchased edition and update entitlement;
documentation access;
security notices and upgrade instructions;
repository changes required by your application.

Implementation cost: use the backlog

Estimate from your own scoped backlog:

list the required product modules;
mark each candidate's module as verified, partial, absent, or unverified;
write acceptance tests before estimating the gap;
include migration, deployment, support, and security work;
record uncertainty for private code you have not reviewed.

There is no reproducible comparison receipt for implementation duration or dependency count across these products. The starting point, product scope, versions, developer experience, and definition of done all change the result.

Best fit cards

Choose create-t3-app when

You want to own the product architecture, the current selectable stack fits the team, and the backlog includes time for billing, email, admin, organizations, and other required modules.

Choose ShipFast when

The current edition's verified modules match a small product's requirements and the commercial terms fit the intended projects and update plan.

Choose Supastarter when

The current edition and plan document the required B2B surfaces, and the team accepts the plan scope and repository architecture after inspection.

Build a small canary before deciding when

A critical feature, license term, runtime, or migration path remains unverified. Test the narrowest risky surface instead of choosing from a marketing matrix.

Methodology

This refresh uses current T3 documentation, npm, GitHub repository and release data, plus ShipFast and Supastarter product/documentation pages accessed 2026-08-23. It preserves product identities and removes unsupported implementation times, dependency counts, private-code judgments, community comparisons, and rankings.

Affiliate and data disclosure

StarterPick does not rank these products from affiliate payouts or a private performance dataset. Commercial links are editorial references. Purchase rights, pricing, promotions, and product features must be verified against the current vendor terms.
