Custom architecture resources
Free tools, blueprints, and technical resources for systems architects evaluating custom software development.
What does ERPStack publish for systems architects?
In short: free architecture tools, downloadable blueprints and technical resources for systems architects and CTOs evaluating custom ERP and software development. 2 interactive tools that need no account, 1 Systems Architecture Blueprint generated from 3 answers, and 3 technical manuals on ERP, CRM and DevSecOps topics written on request.
Interactive tools & guides
Both run in the browser with no account. They are also indexed together on the engineering decision tools page, with the constants behind each one written out in full.
Architecture Audit Grader
Evaluate your legacy ERP database designs, Next.js routing patterns, and API gateways against SOC 2, HIPAA, and GDPR compliance standards. Get an immediate architectural score, gap analysis report, and remediation checklist.
Systems Architecture Blueprint
Download our reference design guide detailing multi-tenant schema-level PostgreSQL isolation, Edge middleware JWT validation, Drizzle ORM optimization patterns, and automated DevSecOps pipelines.
Technical Whitepapers & Design Manuals
Written for evaluations, one request at a time — tell us which manual you need and a senior architect prepares it against your stack. No gated forms, no generic PDFs.
The Strangler Fig Migration Manual
A step-by-step technical handbook detailing how to progressively migrate legacy SAP and Oracle NetSuite architectures to modern decoupled Next.js enclaves. Learn how to design routing filters at the proxy level to extract database routines and domain queries without taking systems offline.
Request this manualB2B SaaS Multi-Tenancy Partitioning Patterns
An exhaustive comparative analysis between tenant-key data segregation, schema-level partitioning, and fully isolated PostgreSQL database clusters. Includes performance benchmark charts, connection pool scaling strategies via PgBouncer, and Row-Level Security configuration templates.
Request this manualDevSecOps Systems Verification & Compliance Blueprint
A reference manual mapping out continuous security verification for regulated platforms. Details the exact setup needed for automated Semgrep static scanning, Arcjet edge rate-limiting, and Playwright system execution suites in pre-merge integration pipelines to pass SOC 2 and HIPAA procurement audits.
Request this manualQuestions about these resources
The tools return a result in about 5 minutes; the 13-section Systems Architecture Blueprint is generated from 3 answers and a work email; the manuals are written by a senior architect against your own PostgreSQL, Next.js or legacy stack. The technology stack and the ERP ROI Calculator sit behind everything listed above.
Which custom resource should you start with?
Start with the Architecture Audit Grader if you already run an ERP or CRM: 5 questions, about 5 minutes, and a score out of 100 that names the structural gaps in hosting, authentication, multi-tenant isolation and release cadence. Start with the Systems Architecture Blueprint if you are specifying something new, because it turns 3 answers about your sector, scale and role into a 13-section custom document. Start with the ERP ROI Calculator if the open question is budget rather than architecture. Most evaluations run all 3, in that order, over about 20 minutes.
How do these custom resources relate to each other?
They are 3 views of 1 reference architecture. The grader scores your current system against it, the blueprint writes it out for your profile, and the calculator prices the move to it against 3 years of per-seat SaaS licensing at $1,188 per user. The technology page lists the 24 components that architecture is built from, Next.js, React, TypeScript, PostgreSQL, Redis, Terraform, AWS and Microsoft Azure among them, and the pricing page states what a custom ERP build costs.
Are these custom architecture resources free?
Yes, all of them. Both tools run without an account and show a result immediately. The Systems Architecture Blueprint asks for 3 inputs and a work email, because the 13-section document is generated against your answers rather than pulled off a shelf: 96 editions exist across 6 sectors, 4 scales and 4 roles. The 3 technical manuals are prepared on request against your own custom stack, whether that is SAP, Oracle NetSuite, Odoo or a legacy in-house ERP.
Do you publish generic PDF whitepapers?
No. Every manual listed among these architecture resources is written against the requesting company's own stack, which is why the page asks you to name the one you need instead of offering a library of downloads. A generic PDF on multi-tenant PostgreSQL partitioning repeats what is already free elsewhere. A document that reads your schema, your tenancy model and your SOC 2, HIPAA or GDPR scope is the part that is actually scarce, and it takes an engineer rather than a template. The 3 manuals above cover migration strategy, multi-tenant database design and DevSecOps verification.
Who writes these custom architecture resources?
The same engineers who deliver the engagements, working from the reference architecture the blueprint page calls the design deployed on every engagement. ERPStack is remote-first, so a request routes to a senior architect rather than to a content team, and the custom manual cites the standards, patterns and tooling a real build would use: PostgreSQL with Row-Level Security, Drizzle ORM, Terraform, Semgrep SAST, OWASP ZAP and RBAC enforced below the API.
