Factual comparisons
These tables compare documented product attributes only. They are not endorsements, not reviews, and not rankings. Attributes we cannot state factually are marked "varies".
CRM Dedup Kit vs manual spreadsheet cleanup
| Attribute | CRM Dedup & Migration Cleanup Kit | Manual spreadsheet cleanup |
|---|
| Normalization | Built in: emails, E.164 phones, domains, company suffixes, nickname canonicalization | Manual formulas; varies by author |
|---|
| Duplicate detection | Fuzzy matching with confidence tiers + union-find clustering | Eyeballing + exact-match functions; varies |
|---|
| Merge safety | Dry-run merge plans reviewed before anything changes; 54/54 tests pass | Undo history only; no dry-run model |
|---|
| Change audit trail | Machine-readable change logs (JSON + CSV) with before/after values | Varies; usually none |
|---|
| Export | Import-ready CSV export | Manual CSV export; varies |
|---|
| Time model | One-time setup, then automated runs | Hours scale roughly linearly with row count; varies |
|---|
| Error risk | Low-confidence matches flagged for human review | Human error; varies |
|---|
| Privacy / offline | Fully offline; data never leaves your machine | Local spreadsheet: also offline; cloud spreadsheet: varies |
|---|
| Pricing structure | $149 one-time, single-seat perpetual | Your labor cost; varies |
|---|
Limitation: the kit works on CSV exports, not live CRM APIs.
One-time-license utility vs recurring SaaS
This compares the model, not any specific SaaS product.
| Attribute | Payload one-time utilities ($49–$149) | Recurring SaaS alternative |
|---|
| Pricing structure | Single payment; single-seat perpetual license; 14-day refund if not as documented | Recurring (monthly/annual); varies |
|---|
| Ongoing cost | $0 after purchase | Varies with tier and seat count |
|---|
| Data locality | Local: tools run on your machine or browser; no accounts | Typically cloud-hosted; varies |
|---|
| Offline capability | Yes: StableLedger, CRM kit, and the scanners run fully offline; the Chrome extension is 100% client-side | Usually requires a connection; varies |
|---|
| Updates | Current shipped version; no ongoing delivery obligation | Continuous; varies |
|---|
| Managed hosting | Not included — these are local utilities, not managed services | Usually included; varies |
|---|
Choose the one-time utility when the job is bounded and local. Choose SaaS when you need managed hosting, collaboration, or ongoing delivery — things these utilities do not provide.
MCP Launch Readiness Audit vs a basic open-source scanner
| Attribute | MCP Launch Readiness Audit | Basic open-source scanner |
|---|
| Checks covered | 48 documented rules: tool poisoning, hardcoded credentials, server exposure, over-privileged tools, SSRF, missing auth/hardening | Varies by project |
|---|
| Fix guidance | Every finding ships with a concrete remediation (code snippet or config change) | Varies; often detection-only |
|---|
| Report output | Branded audit report; findings logged with outcomes | Varies |
|---|
| Hardened templates | Included | Varies |
|---|
| Stress-test harness | Included: reliability harness under hostile traffic | Varies |
|---|
| CI wiring | CI workflow included | Varies |
|---|
| Pricing structure | $79 one-time, single-seat perpetual | Varies (often free) |
|---|
| What it is not | An audit, not a certification; not penetration testing | Varies |
|---|
We cannot state what any specific open-source scanner does or does not cover — evaluate each project on its own documentation.
