2026-06-16Pricing — monthly subscription replaces the lifetime founder seat

StackPatch is now a monthly subscription from $9/mo, with a 14-day free trial

New pricing: Free (3 servers, up from 1) · Solo $9/mo (3 servers) · Pro $29/mo (10 servers) · Team $79/mo (unlimited). Annual billing is 2 months free. Every paid plan starts a 14-day free trial with no card required.
The $99 one-time lifetime founder seat is closed to new signups. The 50 founders who bought it keep lifetime access to everything, forever — no rug-pull, no price hike, no V2 paywall on what they bought.
Why: a one-time price on a tool with ongoing per-server scan cost does not sustain the product, and the indie patch-ops market (SysWard, LinuxPatch) is priced monthly. A low monthly with a no-card trial converts the free-scan traffic into recurring support for the product.
Mechanics: monthly/annual Stripe Checkout with a no-card trial, a single pricing source of truth, and tier-based server limits provisioned automatically on signup. Verified end-to-end before ship.

2026-06-02V2.0 — exploitability prioritization (CISA KEV + EPSS)

Every scan now tells you which CVEs are actually being exploited — not just which exist

Added CISA KEV (Known Exploited Vulnerabilities) overlay: any matched CVE that is being actively exploited in the wild is flagged "Actively exploited", sorted to the top of your results, and ransomware-linked CVEs are called out separately. A KEV match bumps the finding to at least high severity — because a confirmed-behind version of an actively-exploited CVE is the single highest-priority thing on a box.
Added FIRST EPSS (Exploit Prediction Scoring System) scores: every finding shows its 0–100% probability of being exploited in the next 30 days, so a long list of CVEs becomes a ranked "patch these first" order instead of an undifferentiated wall.
New one-line summary on vulnerable scans — e.g. "Patch these first: 2 actively exploited (CISA KEV), 1 ransomware-linked · 3 with >10% 30-day exploit probability." This is the prioritization layer commercial scanners charge for, built entirely from free public data.
Both feeds refresh daily on the server; the scan payload is unchanged (still just your distro/kernel/package list, no signup). Clean boxes stay clean — the overlay only annotates real, confirmed-vulnerable findings.

2026-06-01V1.9 — free quickscan goes multi-distro + EOL detection + posture grade

The free curl|bash scan now covers 5 distros, flags end-of-life OS, and gives an A–F grade

Free quickscan now auto-detects your package manager and scans Debian/Ubuntu (apt), Alpine (apk), and Rocky/AlmaLinux (rpm) — previously apt-only. Verified end-to-end against real Ubuntu, Alpine, and AlmaLinux containers (clean boxes correctly report 0 findings; deliberately-old packages correctly flagged).
Caught and fixed an RPM epoch bug before it shipped: dropping the package epoch made every epoch-0 install look older than an epoch-1 advisory, producing ~16 false positives on a stock AlmaLinux 9 box. The collector now sends the real epoch.
Added end-of-life OS detection — the scan flags releases whose security support has ended (e.g. Ubuntu 18.04, Debian 10, RHEL/CentOS 7) with the EOL date, because an unsupported base means new CVEs are never fixed.
Added a reboot-required check — flags when installed security updates (often a kernel) need a reboot to take effect, because a patched-but-not-rebooted box is still running the vulnerable code.
Added an A–F posture grade + one-line summary to every scan (A = clean and supported; F = a critical issue or an EOL OS) — a fast, shareable read on where a server stands.

2026-05-31V1.8 — quickscan accuracy + free-scan-first landing

Two matching-accuracy fixes shipped; /patch now leads with the free quickscan

/patch hero now leads with the free quickscan (copyable curl one-liner, no signup, read-only, source is readable). The $99 lifetime founder seat moves to the upgrade slot — the free scan is the way in.
Fixed a CVE-2026-31431 (algif_aead "Copy Fail") false positive: the kernel check previously flagged ANY 3.x–6.x kernel as a confirmed HIGH vuln, but patch status cannot be determined from `uname -r` (distros backport the fix without changing the version string). Reframed to an honest medium-severity heuristic advisory ("verify patch status"; the modprobe blacklist remains a safe, no-downside mitigation), and Microsoft/WSL kernels are no longer flagged (they are not apt-updatable).
Fixed misleading remediation commands for Ubuntu Pro (ESM) advisories: fixes shipped only via +esm versions now show `sudo pro enable esm-apps esm-infra` plus an honest note, instead of a plain `apt upgrade` that silently no-ops without Pro enabled.
GitHub Action scaffold added (runs the same quickscan in CI and annotates the build; reuses the existing quickscan API). Not yet published to the Marketplace.

2026-05-13V1.7 — free tier opened + weekly digest

Freemium activated end-to-end; 3 new dev.to articles live; IndexNow + reciprocal SEO

/patch free tier flipped from "coming soon" to "open now" — Free tier card gets "Open now" badge + "Sign up free" CTA scrolling to #waitlist anchor
Welcome email subject + body rewritten — "you are on the waitlist" → "you are on the free tier"; added plaintext fallback for clients that strip HTML; copy commits to weekly digest landing every Monday
stackpatch-weekly-digest.py shipped (Mondays 14:00 UTC cron) — matches each signup's distro hint to advisories newly arrived in past 7 days, top-8 personalized digest via Resend, idempotent on (email, ISO-week) — fulfills the welcome-email promise
3 fresh dev.to articles published — matcher internals (canonical to /patch/how-to-patch-linux-cves), Vuls/Trivy/Grype comparison (canonical to /patch/scanners-comparison), $7/mo VPS security stack (canonical to /patch/free-cve-scanner); each verified HTTP 200
devto_poster.py shipped — YAML-frontmatter POST.md → dev.to API → audit-log record. Two real-world fixes during execution: default Python-urllib UA was WAF-blocked (added explicit UA); dev.to canonicals are one-shot per platform (each draft re-canonicalled to a distinct /patch subpage)
indexnow_submit.py shipped — 25-URL priority surface set pushed to api.indexnow.org + bing.com/indexnow (both 200 OK). IndexNow ownership key live at /ee109f53b8946494344c14aa5cdb1f3e.txt
/patch "Latest writeups" section added between Pricing FAQ and Final CTA — 4 outbound dev.to cards (reciprocal SEO, canonical-back to distinct subpages)
/scan.sh CTA copy updated — stale "Join the waitlist (your distro)" → "Sign up free (1 server, weekly digest)"

2026-05-01V1.6 — distribution + checkout polish

Apple Pay enabled at checkout, dev.to launch shipped, full V1 copy parity, JSON-LD on every comparison page

Apple Pay domain `mindsparkstack.com` registered with Stripe — Apple Pay now appears at /patch checkout for iOS users (was previously only enabled on Stripe-hosted buy.stripe.com)
dev.to build-log article published — first real distribution into the indie-dev community, canonical to /patch
/patch hero badge updated to V1 status with live distro / CVE counts; secondary waitlist card no longer claims "MVP launches in 7-14 days"
Welcome email body rewritten — drops the never-wired "Pro free 30 days" and time-bound MVP claim, leads with V1 live + LTD founder seat
Homepage Free quickscan bullet + site-wide meta description now list all 5 distros (Ubuntu/Debian/Alpine/AlmaLinux/Rocky) — was 2-3 distros
JSON-LD WebPage + SoftwareApplication schemas on /patch/vs-vuls, /patch/vs-trivy, /patch/vs-grype, /patch/vs-snyk — Google rich-results uplift on competitor-search queries

2026-04-30V1.5 — autonomous loop completion

Full PRD shipped: paid activation loop, funnel instrumentation, SEO surfaces

Per-CVE pages now have JSON-LD Article schema + dynamic title/description from cached data — every cached USN/NVD record is now a unique SEO surface
Sitemap is now dynamic, enumerates 100 most-recent USN + 100 most-recent NVD records (was static 23 entries)
/security page — plain-language data handling reference (what we collect/don't, where it lives, retention, breach response, how to verify)
/changelog page — this page
/status page + /api/stackpatch/status — public service health dashboard reading poller state files directly
/patch/usn-8222-1 — second high-search-volume CVE landing (OpenSSH cluster fix)
/patch/cve-2026-31431 — dedicated SEO landing for the kernel local-priv-esc
/patch — pricing FAQ block (6 cards: 3-server limit, after 50 seats, refund, RHEL/Alpine, auto-apply, ESM)
/patch/scan — trust panel + curl|bash one-liner above the form
/patch/audit/[server] — top-level status badge (clean/action_needed/critical/stale), share-with-customers copy block, what-this-doesn't-certify caveats, JSON/CSV export
/patch/onboarding/success — server-side validates Stripe session, idempotent customer + token creation, install command + trust panel

Founder seat counter on /patch reads filesystem (real "X / 50 claimed", no faked scarcity)
Result-conditional quickscan endings — vulnerable/clean/unsupported each get different CTA
Email alert dispatcher cron @ :40 — new findings + stale-host (24h threshold + 72h re-alert dedup)
Stripe customer_id persistence — unblocks future Customer Portal
Stripe payment_link updated to redirect to /patch/onboarding/success?session_id={CHECKOUT_SESSION_ID}

2026-04-30V1.0 — pivot complete

Killed VaultAgent + Fleet Pilot + Fleet Architect; StackPatch is the only product

Header/nav/footer chrome cleanup — was still pitching retired SKUs on every page
Homepage rewritten — announcement bar, hero, FeaturedProducts, FinalCta all StackPatch-only
