Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Knack
- Plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off
- API access is capped per day, at 1,000 calls on the entry plan and 10,000 at the Corporate tier, so a scheduled sync or a busy automation can exhaust the day's quota before the working day ends and integrations then fail silently
- The application itself cannot be exported or self-hosted; records can be downloaded but the pages, roles, flows and business logic exist only inside Knack, so outgrowing the platform means rebuilding the app rather than moving it
- Customisation beyond the builder is limited to injected CSS and JavaScript that Knack's support does not cover, so any non-standard interface behaviour becomes yours to maintain against a DOM the vendor can change without warning
- Compliance capabilities that regulated buyers assume are baseline, HIPAA and GovCloud options, advanced SSO, IP restrictions and private environments, are gated to the Corporate and Enterprise tiers, so a small regulated pilot cannot legitimately start on an entry plan
Terraform
- HCL syntax requires learning a domain-specific language with limited GUI alternatives
- State file management is complex, especially at scale with multiple workspaces
- terraform import workflow is fiddly and must be done one resource at a time
- No native error handling or try-catch capabilities like traditional programming languages
- No automatic rollback capability - must manually delete and re-run if needed

Answered from the vendors’ own pages
Knack: Is Knack charged per user?
No. User accounts are unlimited on all plans. Plans are bounded by stored record count, file storage, API calls per day and automation transactions.
Terraform: Is there a free tier?
Yes. The free tier supports up to 500 managed resources and 1 concurrent run. The legacy free tier ends March 31, 2026; remaining organizations auto-convert to the enhanced free tier.
SourceKnack: What happens when I exceed the record limit?
You move to a higher tier or reduce stored records. Because the limit is on data rather than people, apps that accumulate history hit it while apps that track a fixed set of entities generally do not.
Terraform: What clouds does Terraform support?
Terraform supports AWS, Microsoft Azure, Google Cloud Platform, Oracle Cloud, Docker, and HashiCorp's own HCP Terraform managed service, with over 2000 providers available.
SourceKnack: Can I export my application or self-host it?
You can export record data. The application itself, its pages, roles, permissions and flows, is not exportable and cannot be self-hosted, so leaving means rebuilding elsewhere.
Terraform: Do I need HCP Terraform Cloud or can I run locally?
Terraform runs locally by default, storing state on your machine. For team collaboration and production use, remote backends like S3, Azure Storage, or HCP Terraform are recommended for locking and security.
SourceKnack: Is it suitable for public-facing portals?
That is its strongest case, because logins are unlimited and role-based permissions are built in. The constraint is record volume and API throughput, not audience size.
Terraform: Is HCL hard to learn?
HCL is designed to be human-readable and sits between JSON and YAML. It supports comments, variables, functions, and conditional logic. While beginners can get started quickly, mastering advanced features takes practice.
SourceKnack: Can I use it for regulated data?
HIPAA-aligned and government cloud options exist but only on the Enterprise tier, along with private server environments. Lower tiers should not be used for regulated workloads.
