The short version

  • Each has a real cost: Appsmith the free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories; Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • They diverge on capability: Appsmith covers Drag-and-drop builder, Atlantis covers Pull request plans.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Appsmith

  • The free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories
  • Workflows, custom roles and audit logs all require the Business plan at $15 per user per month
  • SAML and OIDC single sign-on need Enterprise, which starts at $2,500 a month with a 100 user minimum
  • Embedding an app privately is Enterprise only; the lower tiers embed publicly
  • Managed hosting is an Enterprise add-on rather than an included option

Atlantis

  • There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
  • It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
  • It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
  • Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

Answered from the vendors’ own pages

Appsmith: How much does Appsmith cost?

Appsmith offers a free plan for up to 5 users, a Business plan at $15 per user per month (up to 99 users), and an Enterprise plan starting at $2,500 per month for a minimum of 100 users with unlimited users available at that rate.

Source
Atlantis: Is there a company behind Atlantis?

No. It runs as a series of LF Projects under the Linux Foundation and is maintained by volunteers. There is no vendor to buy support from and no service level agreement.

Appsmith: Does Appsmith have a free version?

Yes, Appsmith's Free plan provides access for up to 5 users with 5 workspaces, 3 Git repos, and community support at no cost. All plans offer unlimited apps.

Source
Atlantis: Is it a CNCF project?

No. It uses a channel in the CNCF Slack, which is often misread as membership, but the project sits under LF Projects rather than the CNCF.

Appsmith: What does the Business plan include compared to Free?

The Business plan at $15 per user per month supports up to 99 users, provides unlimited workspaces and Git repos, includes workflows and reusable packages, premium integrations, custom roles, and access controls with email and chat support compared to the Free plan's community support only.

Source
Atlantis: Does it work with OpenTofu?

Yes, there is a dedicated integration guide alongside Terraform, and it also has configuration for working with hosted Terraform backends.

Appsmith: How are Appsmith users counted for billing purposes?

Appsmith counts any user who builds or edits applications as a standard user for billing. Developers and builders are treated the same as other users and all users count toward the per-user billing model without separate developer seat charges.

Source
Atlantis: What does it not do that a paid platform does?

Drift detection, cost estimation, a managed state and run interface, and a real policy engine. Atlantis does pull request plan and apply well and stops there.
