Caspio: The AppSheet Alternative
Google's no-code app builder shines for mobile field apps on Workspace data. When compliance, data volume, and user counts get serious, teams look here.
Caspio is an AI platform for building custom business apps and the AppSheet alternative for teams that need annually certified HIPAA, SOC 2 Type II, and GDPR compliance, unlimited users on every plan, and a SQL Server data core built for growing data volumes.
HIPAA You Can Start With, Not Engineer Yourself
AppSheet has a HIPAA path: it sits on Google Workspace's HIPAA Included Functionality list (as of May 14, 2026), and covered entities can accept Google's BAA from a Workspace super administrator account. Then the work begins. Google's own implementation guide makes compliance configuration your job end to end: classify PHI fields as sensitive so they are obscured in audit logs, keep PHI out of app definitions, data source names, and view names, and keep it out of support tickets. There is no published HIPAA package or price, and the enhanced application security and governance controls regulated deployments lean on sit in the Enterprise Plus tier, managed by your Workspace administrator.
Caspio's HIPAA compliance controls are independently certified every year, HIPAA coverage is available with every plan through a compliance add-on on separate compliant infrastructure, and Caspio's HIPAA-eligible AI features operate under signed Business Associate Agreements (BAAs). Compliance is built into the platform, rather than assembled through customer-managed configuration.

Unlimited Users on Every Plan
AppSheet charges per user on Starter, Core, and Enterprise Plus, so every field worker, contractor, and customer who signs in is a billable seat. The exception, Publisher Pro, is priced per app but supports only public applications with no sign-in and no security filters; Google's own guidance is to assume all the data in such an app is visible to anybody.
Caspio includes unlimited users on every plan, signed-in and secured, at one flat platform price. Roll an app out to 50 users or 5,000 and the platform price does not move.
A SQL Server Data Core, Not a Spreadsheet Ceiling
AppSheet is spreadsheet-first, and Google's own documentation treats sync latency and large datasets as constraints to be managed with security filters, data partitions, and trimmed virtual columns. AppSheet Database caps at 2,500 rows per database below Enterprise Plus, and a documented community case reported average syncs of about 35 seconds once a table with virtual columns passed 20,000 rows.
Caspio applications run on a SQL Server data core with role-based access and record-level security, built on more than two decades of platform engineering and trusted by 15,000 organizations worldwide. The platform is designed to support large datasets without requiring a shift away from the underlying architecture.
Four AI Capabilities, One Security Model
Caspio offers four AI capabilities, available on every plan tier. All four run against the same SQL Server data core, so AI works on your full dataset, not a synced spreadsheet.

Google AppSheet is a per-user no-code builder, strongest in mobile field apps that live on Google Workspace data. Caspio is an AI application platform with unlimited users, annually certified compliance, and a SQL Server data core. Here’s a side-by-side comparison.
| Comparison area | Caspio | Google AppSheet |
|---|---|---|
| Pricing model | Unlimited users on every plan; published plan pricing | Per-user plans (Starter, Core, Enterprise Plus); Publisher Pro priced per app for public, no-sign-in apps only |
| Compliance | HIPAA, SOC 2 Type II, and GDPR independently certified annually; HIPAA available with every plan via a published add-on | HIPAA-eligible under the Google Workspace umbrella; BAA self-served by a Workspace admin; PHI safeguards configured and policed by the customer; no published HIPAA package |
| AI app generation | Caspi generates applications from a description, including the data model, interface, and roles, plus In-App AI Chat Agent, AI Connector Extensions, and Caspio MCP Server | Gemini for App Creation on all paid accounts; AI Tasks in automations gated to Enterprise Plus |
| Data scale | SQL Server data core with role-based access and record-level security, built for millions of records | Spreadsheet-first; AppSheet Database capped at 2,500 rows per database below Enterprise Plus; sync latency managed with partitions and filters |
| Deployment | A complete Caspio-hosted application or web-native embeddable components on any site, portal, or CMS | Mobile-first apps for signed-in users; public apps require Publisher Pro, with no sign-in and no security filters |
| Support | 24/7 human support on every plan, handled in-house | Email support on Core; priority support reserved for Enterprise Plus; none listed on Starter |
Where AppSheet Is Strong, and Where It Strains
AppSheet’s strengths are real. Gemini for App Creation generates apps from prompts on all paid accounts, and the October 2025 Gemini updates added AI Tasks that extract data from photos and PDFs and categorize requests inside automations. The pairing: AI Tasks are gated to Enterprise Plus, and because every user is a billable seat, costs can increase as adoption expands across more users.
Workspace bundling is the other genuine draw: AppSheet Core is included in most paid Google Workspace plans. The paired truth is that the bundled tier is not the regulated-deployment tier. Enhanced application security, team management, governance controls, and AI Tasks all sit in Enterprise Plus, which requires Google Workspace Administrator status. Organizations should evaluate whether the bundled plan includes the governance and security features their deployment requires.
And for teams asking the HIPAA question directly: AppSheet is HIPAA-eligible, but the implementation responsibilities remain with the customer, from the admin-accepted BAA to PHI hygiene rules you must engineer and police, with no published package price.
Best for, AppSheet: Mobile field apps for signed-in Workspace teams working on Google Sheets data.
Caspio’s HIPAA controls are independently certified annually, published, and available with every plan, alongside 24/7 human support instead of email tiers.
Best for, Caspio: Teams that want AI app building and annually certified compliance on one platform, with unlimited users and serious data volumes at published prices.
Comparing Caspio and AppSheet From the Other Direction?
If you are weighing Caspio against AppSheet, consider three questions: what your per-user bill looks like when the app succeeds and everyone needs access; which platform's compliance is certified, published, and available on the plan you would actually buy; and what happens to performance when your data outgrows a spreadsheet. Caspio's answers are unlimited users, annually certified compliance with every plan, and a SQL Server data core. See why teams choose Caspio for the full comparison across platforms.
Frequently Asked Questions
Caspio is a leading choice among AppSheet alternatives for teams that need certified compliance and unlimited users. Caspio is an AI platform for building custom business applications, with HIPAA, SOC 2 Type II, and GDPR compliance independently certified annually, a SQL Server data core, and no per-user fees on any plan.
AppSheet charges per user, runs spreadsheet-first with row caps below Enterprise Plus, and leaves HIPAA configuration to the customer under Google’s Workspace BAA. Caspio includes unlimited users on every plan, runs on a SQL Server data core, and certifies HIPAA, SOC 2 Type II, and GDPR compliance independently every year. Which is better depends on the workload: AppSheet fits mobile field apps on Workspace data; Caspio fits regulated applications with serious data volumes and user counts.
AppSheet is HIPAA-eligible under Google Workspace: it appears on Google’s HIPAA Included Functionality list, and a Workspace super administrator can accept Google’s BAA. The customer then configures and polices PHI safeguards per Google’s implementation guide, and there is no published HIPAA package or price. Caspio takes a different approach: HIPAA compliance controls independently certified annually, with a published add-on available on every plan.
No. Caspio does not charge per user or per seat. Every plan includes unlimited users, so the app that spreads across your whole workforce costs the same platform price as the pilot. Plans start from $300/month.
Caspio does not offer a free plan, and AppSheet’s free usage is for building and testing with up to 10 test users before licenses are purchased. Every Caspio plan comes with a free 14-day trial, so you can build and test a real application, with real users, before you buy.
Yes. Caspio’s HIPAA compliance controls are independently certified every year, and HIPAA coverage is available with every plan through a published compliance add-on running on separate compliant infrastructure. Details are on the Caspio HIPAA Edition page.
