The short version

  • Only WeWeb has a free tier, so it costs nothing to try first.
  • Each has a real cost: Appian cost multiplies on three axes at once, users, apps and month, so deploying several apps to overlapping user populations produces a bill that is not obvious from any single per-user headline figure.; WeWeb there is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.
  • They diverge on capability: Appian covers Low-code process designer, WeWeb covers Backend agnostic.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Appian

  • A regulated enterprise (financial services, government, insurance) automating case management processes that need a full audit trailnot WeWeb
  • A company deploying RPA bots alongside low-code apps and wanting both in one licensed platformnot WeWeb
  • An organisation whose process data volume is large enough that the Standard tier's 4 million row cap is a real constraint worth planning fornot WeWeb
  • A business wanting embedded AI actions inside workflow steps rather than bolted on separatelynot WeWeb

WeWeb

  • Building an interface over data that already lives in Supabase or PostgreSQLnot Appian
  • Agency work where the client contract requires an application that runs without the vendornot Appian
  • Replacing the front end of a no-code application that has outgrown its original platformnot Appian
  • Internal tools for staff where the database and its permissions already exist and must not be duplicatednot Appian

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Appian

  • Cost multiplies on three axes at once, users, apps and month, so deploying several apps to overlapping user populations produces a bill that is not obvious from any single per-user headline figure.
  • Each tier has hard caps on data rows, RPA bots and monthly AI actions, so a workload can force a tier upgrade purely from data or automation volume growth, independent of user count.
  • No dollar figures are published anywhere on Appian's own site; every real price point comes from a sales negotiation, making early-stage budget comparison against OutSystems or Mendix difficult.
  • The platform's strength in process orchestration and case management is less useful for teams that mainly want simple departmental data apps, where the pricing and capability are overkill.
  • Exceeding the 200,000 (Standard) or 1,000,000 (Premium) monthly AI action allowance requires a renegotiation, so AI-heavy workflows carry real usage risk beyond the base subscription.

WeWeb

  • There is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.
  • Self-hosting and the more useful delivery options sit on higher tiers, so on entry plans you are hosting with WeWeb and depending on its uptime for a production application.
  • The learning curve is closer to a front-end framework than to a drag and drop builder; collections, bindings and state assume you understand how data flows through an interface, which defeats non-technical buyers.
  • Output is web only. There is no native mobile build, so anything that must appear in the App Store needs a wrapper or a different tool entirely.
  • It is a small European vendor competing against far larger platforms, so procurement teams that assess supplier viability, support depth and long-term roadmap will need convincing before signing.

Answered from the vendors’ own pages

Appian: Does Appian publish its prices?

No dollar figures are public. It discloses the pricing mechanism, per user per app per month across three tiers, but actual rates are negotiated.

WeWeb: Do I need another product to use WeWeb?

Yes. It builds the front end only. You need a backend such as Supabase, an existing database or an API before the application does anything useful.

Appian: What happens if we exceed the data row cap?

Exceeding a tier's data row, RPA bot or AI action cap requires upgrading to the next tier or negotiating an add-on, regardless of user count.

WeWeb: Can I host the app myself?

On the higher tiers, yes. That is one of the main reasons agencies choose it, because the delivered application can run without the vendor in the path.

Appian: Is Appian a general app builder like OutSystems?

It can build general apps but is oriented more toward process automation and case management, with RPA and AI embedded as core features.

WeWeb: Is it suitable for someone who cannot code?

Less so than most no-code builders. You do not have to write code, but you do have to think like a front-end developer about state, collections and bindings.
