The short version
- Each has a real cost: 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.; Deno Deploy smaller ecosystem compared to AWS Lambda with fewer third-party integrations
- They diverge on capability: Atlantis covers Pull request plans, Deno Deploy covers Edge Functions.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Deno Deploy
- Smaller ecosystem compared to AWS Lambda with fewer third-party integrations
- Less mature than established serverless platforms; newer company and platform
- 1GB deployment size limit may restrict larger applications
- 512MB memory limit lower than some competitors for memory-intensive workloads
- Smaller user base and community compared to Lambda or Netlify

Questions people ask
- Is Atlantis or Deno Deploy better?
- Neither clearly leads. Atlantis starts at Free and Deno Deploy at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Atlantis or Deno Deploy?
- Atlantis starts at Free and Deno Deploy at Free.
- Does Atlantis or Deno Deploy run on more platforms?
- Atlantis runs on Linux, Docker, Kubernetes, Self-hosted. Deno Deploy runs on Cloud/Web.
- Can I use Atlantis for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Atlantis best used for?
- Atlantis is most often used for making terraform review meaningful by putting the actual plan output in front of the approver, removing local applies and the credential sprawl that comes with every engineer holding production keys, getting pull request driven infrastructure without paying a per-user subscription for a hosted platform, enforcing conftest policies as a blocking check before an apply can run. Of those, making terraform review meaningful by putting the actual plan output in front of the approver and removing local applies and the credential sprawl that comes with every engineer holding production keys are not what Deno Deploy is typically brought in for.

- Atlantis covers Pull request plans, Comment driven apply, Workspace locking, Policy checking. Deno Deploy covers Edge Functions, Deno KV, Automatic HTTPS, Global Distribution.
Answered from the vendors’ own pages
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.
Deno Deploy: What does Deno Deploy's free tier include?
Deno Deploy free tier includes 1 million requests per month, 100 GB of outbound bandwidth, 50 milliseconds of CPU time per request, 50 custom domains, 1 GiB of KV storage, and up to 5 team members.
SourceAtlantis: 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.
Deno Deploy: What are Deno Deploy's Pro plan features and pricing?
Deno Deploy Pro costs $20/month and removes request limits, increases KV storage to 5GB, and includes priority support. Additional storage beyond 5GB costs $0.75/GiB.
SourceAtlantis: 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.
Deno Deploy: What are the deployment size and memory limits for Deno Deploy?
The total size of all files within a deployment (source files and static files) should not exceed 1 gigabyte. Applications have a maximum memory allocation of 512MB.
SourceAtlantis: 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.
Deno Deploy: Does Deno Deploy support TypeScript natively?
Yes. Deno Deploy runs TypeScript natively with zero-configuration TypeScript support. Code can be written in TypeScript or JavaScript and runs on the same V8 engine.
SourceDeno Deploy: What security features does Deno Deploy provide?
Deno Deploy features an opt-in permission system to mitigate supply chain attacks. Permissions can be explicitly granted for file, network, and environment access, running code securely by default.
