App Builder Index

The rankings

Every builder, every axis, 2026

The default order is our weighted overall rating. Click any column heading to sort by that axis instead, which is the honest way to use this table: the overall number is a summary, and the axis that matters to you is the one that should decide. Weights are published on how we review and are identical for every tool. All ratings are out of five to one decimal. Most recent verification: 6 September 2026.

Every column sorts. The default order is the published rank, which is the weighted overall rating described on how we review. Axis abbreviations, in column order: Rel. is Reliability, Integ. is Integrations, SEO is SEO and GEO, Design is Design quality, Agent is Agent performance, Speed is Speed, Value is Value, Scale is Scalability, API is API and MCP access, Own. is Code ownership.

Prices are shown in the currency each vendor publishes, never converted. Sorting by price groups the currencies and orders within each one, so it is not an exact cross-currency comparison.

n/a means the axis does not apply to this tool. It builds internal software behind a login, a native store app or an API, so there are no public crawlable pages to test. The axis is left out of the overall rating and the remaining weights are renormalised, rather than the tool being scored down for something we did not test.

Who leads each axis

No tool leads more than three of the ten. That is the most useful fact on this page, and the reason we publish axes rather than one number.

What each axis measures

Reliability 16%
Does the thing keep working. We count failed builds, broken deploys, silent data loss, agent runs that end in an unrecoverable state, and how often a finished feature stops working after an unrelated change. Weighted highest because a builder that is fast and broken is worth less than one that is slow and dependable.
Integrations 16%
How much of a real product you can assemble without leaving the tool. Auth, database, payments, email, file storage, webhooks, third-party APIs. We score both breadth and how much manual wiring each connection actually takes.
SEO and GEO 13%
Whether the output can be found. Server rendering, crawlable markup without JavaScript, metadata and canonical control, structured data, sitemaps and robots, page speed, and whether the pages are legible to answer engines and large language models as well as to classic crawlers.
Design quality 12%
How the default output looks and behaves before a designer touches it. Typography, spacing, responsive behaviour, dark and light handling, accessible contrast and focus states, and whether every project comes out looking like the same template.
Agent performance 10%
How well the agent understands a brief, plans multi-file work, recovers from its own mistakes, and holds context across a long session. Measured with a fixed set of briefs run three times each, scoring completion, regressions introduced, and prompts needed per finished feature.
Speed 9%
Time to a first running screen, time to a deployed URL, and iteration latency once the project has real files in it. We measure wall-clock time on identical briefs, not marketing claims.
Value 9%
What a finished feature actually costs. We record real spend across our test builds, including credits and tokens burned on failed attempts, then compare it against what the tool delivered. Cheap tools that need three retries are not cheap.
Scalability 7%
What happens as the project grows: background jobs, scheduled tasks, queues, migrations, file volume, concurrent users, and whether you can reach the underlying infrastructure when the defaults are no longer enough.
API and MCP access 5%
Whether the platform is programmable from outside: documented REST or GraphQL access, webhooks, CLI, and an MCP server so other agents and scripts can drive it. Increasingly the difference between a tool and a component.
Code ownership 3%
Can you leave. Full source export, real two-way version control, no proprietary runtime required to run the result, and a realistic self-hosting path. Weighted lowest of the ten because most buyers never exercise it, and weighted at all because the ones who need it need it badly.
