The short version

  • Only Thunkable 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.; Thunkable every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • They diverge on capability: Appian covers Low-code process designer, Thunkable covers Block-based logic editor.
  • Prices and features above were last checked on 1 September 2026.

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.

Thunkable

  • Every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • Only the Builder tier and above allow a live published app at all in useful numbers, so the entry-level paid plan cannot actually get an app onto the store in a meaningful way.
  • Block-based logic becomes unwieldy for apps with genuinely complex business rules, and there is no clean escape hatch to written code within the platform.
  • Native integrations and performance-sensitive features (heavy graphics, background processing) are limited compared to a coded framework, so the tool has a real complexity ceiling.
  • App ownership and export options are more restrictive than an open source framework; leaving the platform typically means rebuilding rather than exporting a portable codebase.

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.

Thunkable: Can I publish an app on the free plan?

The free plan is aimed at building and testing; live publishing capacity in a meaningful way starts on the Builder plan.

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.

Thunkable: What happens if I run out of AI tokens?

AI-assisted generation stops working until the next billing cycle or an upgrade; manual block-based editing still works.

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.

Thunkable: Is this suitable for a complex business app?

No. It is built for simple to moderately complex apps; heavy custom logic and native integrations are better served by a coded framework.
