Select a USP to explore

Shadow DOM Isolation

Zero CSS Leakage. Period.

Widgets that sit in your main application DOM often get broken by your app's global stylesheets (e.g. huge font sizes, color changes, layout issues). NanoLog isolates all styles using a native Web Component Shadow DOM.

Developer First Impressions

Praise from Closed Beta Testers

Read what early SaaS engineers and technical founders say about our CSS isolation and bundle footprint.

"We run a historic vinyl store in Rotherham, and we wanted a frictionless way to let our regulars know when new collectible shipments land without spamming their inbox. NanoLog's inline changelog widget works perfectly as a blog announcement feed. Setup took less than 5 minutes and fits our vintage dark-mode theme beautifully!"

Jason Sayles

CEO @ Riverside Records (Rotherham)

"Keeping our members updated on weekly karaoke nights, pub quizzes, and members-only events is vital for Swinton House. Using the NanoLog widget as a live, interactive announcement feed directly on our homepage has driven incredible engagement. Our weekly event attendance is up noticeably!"

Club Manager

Manager @ Swinton House Club

"The cryptographically secure HMAC validation was a firm requirement for our enterprise customers to prevent duplicate voting or feedback spam. Setting it up was simple and standard. Highly engineered solution."

Live Production Spotlights & Case Studies

Riverside Records

Storefront

Rotherham's premier independent vinyl, memorabilia, and soul record store.

The Challenge: Announcing rare collectibles, fresh vinyl arrivals, and special shop orders without building a custom database and email newsletter loop.

The Solution: Implemented the NanoLog widget on their main store page. Using categories like "Announcement" and "New Arrival", their visitors click the trigger to inspect lists of new vinyl immediately.

35% Higher Release-Day Store ClicksZero Site Weight impact

Swinton House Club

Heritage Venue

A beautifully restored Grade II listed historic venue and community club in Rotherham, UK.

The Challenge: Promoting local live music events, members dining pricing, karaoke nights, and historic celebrations natively without cluttering their website layout.

The Solution: Implemented the NanoLog widget to host their weekly social schedules and announcements, pinning key parties (like Valentine's Day events) for absolute visibility.

The Premium Choice

How NanoLog compares

Why settle for heavy, overpriced tracking scripts or waste expensive engineering hours building in-house changelogs?

Capabilities	NanoLog Widget	Legacy Widgets	In-House Builds
CSS Style Isolation Encapsulation inside native Web Component	✓ 100% Shadow DOM isolated	✗ Leaky styling / Heavy Iframes	! Requires high CSS upkeep
User Cohort Targeting Deliver personalized feature release notes	✓ Advanced JSON rulesets	✗ Basic filters or none	! Requires database redesign
Unified 3-in-1 Suite Changelog + Roadmap + Feedback tabs	✓ Included in one single bundle	✗ Separate subscriptions	! Months of custom frontend coding
Widget Bundle Footprint Load times, SEO impact, and speed score	✓ Ultra-lightweight <19.2 KB (Brotli)	✗ Heavy tracking scripts (>120KB)	✓ Low overhead, high dev effort
Price & Engineering Cost Monthly cost or custom developer resources	✓ From $0 to $49/mo	✗ $99 to $249+ every month	✗ $10,000+ initial salary allocation

The Financial Breakdown

Competitor Pricing & Drawbacks

Unlike others who practice predatory feature-gating or scale aggressively based on tracked users, NanoLog keeps pricing transparent, zero-bloat, and developer-friendly.

Provider	Entry Price	Pro / Scale Tier	3-in-1 Unified?	The Biggest Drawback
NanoLog	$0/mo	$49 Pro / $149 Scale	Yes (Unified)	None (Developer-first, Shadow DOM isolated, <19.2 KB Brotli bundle)
Beamer	$49/mo Starter	$99/mo Pro	No	Bloated scripts; requires expensive paid add-ons for feedback/NPS surveys.
Canny.io	Free (25 tracked users limit)	$19+ Core / $79+ Pro (usage-based floor)	Yes	Punishing usage-based pricing scaling automatically per "tracked user"; locks Jira/Linear PM integrations behind Pro plan.
AnnounceKit	$79/mo Essentials	$129/mo Growth	Yes (Gated)	Aggressive feature gating (e.g., simple custom CSS styling requires their $339/mo tier).
Frill.co	$25/mo Startup	$49/mo Business	Yes	Lacks enterprise-grade security like HMAC user verification and advanced rules-based audience targeting.

Our Transparent Core Pricing Philosophy

We don't charge you for styling your own widget, nor do we penalize you with steep price increases as your active user base scales. We believe enterprise security (like HMAC verification) and style isolation should be standard engineering standards—not luxury upgrade metrics.

Developer-Centric Engineering

Real-World Production Scenarios

See how simple it is to programmatically solve cohort targeting and performance challenges using NanoLog.

Scenario A

The Selective Beta Rollout

Deliver pre-release logs, UI warnings, or experimental feature alerts solely to developers or users with `betaTester: true` in their context payload. Protect standard users from confusing beta changelogs.

Scenario B

Targeted Enterprise Incidents

Broadcast critical security patches, migration roadmaps, or server-maintenance warnings strictly to `role: "admin"` users inside specific corporate tenants. Keep basic readers focused on standard product value.

Scenario C

Zero-Bloat Core Web Vitals

Stop penalizing your site speeds. Compiling into a native, standalone Web Component under 19.2 KB (Brotli) allows your pages to load asynchronously with zero main-thread parsing locks. Keep your Lighthouse score perfect.

The B2B SaaS Advantage

Secure, compliant feedback loops.

We built NanoLog specifically for modern B2B SaaS teams who need deep, two-way client communication without exposing sensitive customer data or bloating their codebase.

GDPR & HIPAA Privacy Shield

Ensure absolute compliance. NanoLog gives your clients interactive, paint-style blackout tools to mask sensitive PII directly inside visual feedback.

Before visual screenshots ever leave a user's browser, they can paint solid black redaction blocks over private charts or account details. Combined with automated text filters that mask emails and phone numbers, sensitive customer info never reaches your databases or engineers.

Deep Diagnostic Context

Stop guessing why a feature broke. NanoLog acts as a lightweight client diagnostics bridge, packaging rich developer parameters at the exact moment feedback is sent.

Every submission captures the user's viewport screensize, active browser & operating system (OS), current URL, and real-time client console error logs/exceptions. Securely diagnose and fix SaaS product issues without asking clients for raw HAR files.

Zero-Bloat 3-in-1 Platform

Keep your SaaS page speeds pristine. NanoLog consolidates changelogs, interactive roadmaps, and inbound feedback boards under a single, unified package.

Unlike legacy tools that exceed 120KB and leak styles, our native Web Component delivers a zero-dependency, <19.2 KB (Brotli) Shadow DOM widget delivered via edge CDN. Protect your Google Lighthouse scores and Core Web Vitals at a perfect 100/100.
