SaaS

The SaaS version is the fastest way to get started — no infrastructure to manage, sign up and start writing prompts in under a minute.

Key characteristics

	Detail
Identity	Clerk (email/password, Google, GitHub, SSO on enterprise plans)
Data plane	DynamoDB, AWS-hosted
Cache layer	Redis (graceful degradation if unavailable)
AI features	Prompt optimization via Azure OpenAI
Email	SMTP for org invites
SLA	Per agreement; standard tier is best-effort
Region	US-East default; ask about multi-region

Authentication model

The SaaS authorization model is simpler than on-prem:

1. The API key is validated.
2. The key is checked for user_id.
3. The project's organization is loaded, but not matched against the key — the project itself enforces org-scoped access.

If you're on the SaaS build, you don't need to think about the multi-org membership model described in on-prem(. Each key just works against the projects you have access to.

See Authentication( for the full model.

Install the SaaS SDK

pip install --extra-index-url https://elsai-core-package.optisolbusiness.com/root/elsai-prompts-sass/ elsai-prompts==2.0.0

The SaaS build of the SDK hardcodes the hosted URL — you don't need to set base_url.

from elsai_prompts.prompt_manager import PromptManager

pm = PromptManager(
    api_key="YOUR_KEY",
    project_id="YOUR_PROJECT_ID",
    environment="development",
)

When to choose SaaS

You want to start in minutes

No infrastructure setup, no deployment. Sign up, create a project, write a prompt.

No data-residency requirements

SaaS runs on AWS US-East by default. If you need EU residency or strict data-locality, talk to us — or use on-prem.

Managed upgrades

We upgrade the platform without you doing anything. New features land automatically.

Smaller teams

For teams under ~50 active prompt authors, SaaS is the right default.

When to consider on-prem instead

• Regulatory or contractual data-residency requirements
• Air-gapped or restricted-network environments
• Compliance posture that mandates self-host (SOC2 Type II + specific controls)
• Volume / latency SLAs that benefit from in-VPC deployment

See On-Prem(.

Migrating between SaaS and on-prem

The SDK API is identical between the two. Migration is:

1. Re-create your projects and prompts on the target platform (or use the export/import tooling if available — ask support).
2. Update your application's .env:
   • SaaS → on-prem: add PROMPT_MANAGER_API_URL=https://prompts.your-company.com.
   • On-prem → SaaS: remove that env var.
3. Reinstall the SDK from the appropriate index URL.

No application code changes.
