Most stack problems are interface problems. The repository, database, hosting platform, email provider, billing system, and AI service may each work independently while the customer workflow still fails between them. Build the contracts between systems first.
The seven-stage setup
- 1
Start with the product contract
Write down the users, outcome, critical workflow, information you must store, integrations, risks, and proof that the first release works. A stack is useful only when it supports a defined product.
- 2
Make Git the technical source of truth
Create the repository, protect the main branch, define review and release rules, and keep configuration examples without secrets. Add project and agent instructions before several tools begin changing the same codebase.
- 3
Design the data before choosing the dashboard
Define records, stable identifiers, relationships, ownership, retention, and audit requirements. Use migrations for every schema change. Connect DBeaver or another database client with a least-privilege development role.
- 4
Choose managed infrastructure with clear boundaries
Keep the web application, background work, database, object storage, and secrets as separate concerns. Use development, preview, and production environments. Document rollback and health checks before launch.
- 5
Add services through narrow interfaces
Resend should receive only the information needed for the approved email. Stripe should own payment details while your application stores the customer, plan, entitlement, and event IDs it needs. OpenAI should receive minimized inputs and return editable results for human review.
- 6
Secure every data path
Apply least privilege, tenant isolation, row-level security where appropriate, encryption, secret rotation, request validation, rate limits, audit logs, backups, and tested recovery. Treat connectors as read-only until write access has a specific approved use case.
- 7
Prove the system as a workflow
A successful build is not runtime proof. Test the initiating action, downstream service, stored result, reload or reopen behavior, authorized counterpart view, failure state, and rollback path in the intended environment.
Stack readiness checklist
- Every environment and service has a named purpose and owner.
- Secrets are outside the repository and scoped to the smallest required access.
- Schema changes are versioned, reviewable, reversible, and backed up.
- Payments, email, and AI requests have idempotency, failure handling, and audit evidence.
- Customer data is minimized, isolated, retained for a stated period, and deletable.
- Critical workflows have runtime proof across the systems they touch.
- The team can identify the deployed version and recover from a failed release.
Ask your AI tool for a stack gap analysis
Review the proposed technology stack below as a system. PRODUCT OUTCOME: [Describe the user, problem, and first critical workflow.] PROPOSED COMPONENTS: [List repository, application, database, hosting, email, payments, AI, analytics, and other services.] For each component and interface, return: 1. responsibility and owner 2. data received, stored, and returned 3. authentication and least-privilege requirement 4. failure and retry behavior 5. audit evidence and monitoring 6. test and runtime acceptance criteria 7. unresolved decisions or risks Do not invent configuration, credentials, completed tests, or compliance. Mark unconfirmed choices as proposed and end with the five decisions that should be made first.
Turn the checklist into a saved implementation plan.
The Launch Studio Technology Stack Setup Kit connects these decisions to editable architecture, access, integration, security, deployment, and evidence modules. Studio members can save versions and generate a project-specific working plan.
