|---|---|---|
| Overview | ||
| Core approach | Application and customer portfolio management across all four SPI pillars. | Independent cloud availability testing using distributed agents, redundant accounts and manual event verification. |
| Best fit | Agencies, managed service providers and developers; applications built with Lovable are a focus. | Buyers investigating cloud provider availability and network performance across locations and providers. |
| Operational performance | ||
| Health checks | Website availability and response time checks every 15 minutes. | Homepage says five-minute tests; August 2025 methodology says ten-minute tests. |
| Supabase monitoring | Checks resources, service status, database connections, error logs, backups and database version in your Supabase projects. | Not stated publicly |
| Lovable awareness | Recognises Lovable Cloud apps, records each publish, and prices monthly credit usage from uploaded Settings and Usage screenshots. | Not stated publicly |
| Error logs | Combines Supabase error logs, groups repeats and masks email addresses; acknowledged errors stay quiet until newer occurrences. | Reviews test command errors during manual outage verification. |
| Alerts | Audited warning/critical alerts with acknowledgement comments; alert emails to each team member (opt out or critical only), plus optional SIGNL4 on-call alerting per organisation using its own SIGNL4 webhook, where alerts open and close in SIGNL4 automatically; AI retirement alerts clear after a successful re-scan verifies the issue is resolved. | Not stated publicly |
| History timeline | Releases, alerts, log errors, fixes and AI model additions, lifecycle changes, removals and verified alert clearing. | Stores historical test measurements and manually verified outage records. |
| Public status pages | Optional public status page per app with your logo, live state, response time, 24-hour/30-day/90-day uptime, a 90-day bar strip, automatic incidents (opened after two failed or slow checks, resolved after recovery) with manual updates, scheduled maintenance excluded from uptime, double opt-in email updates for visitors and a footer badge; built from existing 15-minute checks, so no code is added to the app. | Public cloud availability view hosted outside the providers being monitored. |
| Security and compliance | ||
| Advisories and security | Security and compliance checks cover software, hosting, backups, ageing access keys, code flaws and AI model retirement. | Not stated publicly |
| Code vulnerabilities | Checks code libraries daily for known security flaws; fixed findings close automatically and findings can be exported. | Not stated publicly |
| AI model inventory | Weekly linked-GitHub scans identify models, source files and direct-key or Lovable AI use; filter by application. | Not stated publicly |
| AI model lifecycle | Active, Deprecated or Retired; retirement countdowns, suggested replacements and alerts at 90/30/14/7 days and retirement. | Not stated publicly |
| Risk register | Accept risks with reasons and review dates; new severity or expired review dates reopen them. | Not stated publicly |
| Backups and publishing | Tracks last successful backup and publish dates, with configurable age limits and alerts. | Not stated publicly |
| Branding and social previews | Daily checks for default titles, icons and sharing images, plus a 404 page check; single-page apps that send status 200 can be accepted as a risk with a review date. | Not stated publicly |
| Cost and profitability | ||
| Cost tracking | Per-app component costs with exchange rates; ingest forwarded emails or upload PDF invoices, extract supplier, dates, amounts and lines with AI, then review and confirm project cost allocations. | Not stated publicly |
| Cost per licence and margin | Customer licence plans show cost per licence, break-even licence counts and margins per application and customer. | Not stated publicly |
| Capacity and growth | ||
| Weekly capacity review | Reviews seven days of readings per project, with plain-English summaries, costed upgrade recommendations and recent trends. | Not stated publicly |
| Multi-tenant and agency use | One portfolio across customers and applications, with separated customer data and role-based access. | Not stated publicly |
| Free tools | Free public checkers, no sign-up: Lovable security, link preview, CORS, DNSSEC and 404 page (with a picture of the page). | Not stated publicly |

Where SaaS Sentinel is different
Application operations
SaaS Sentinel: checks application availability and Supabase resources every 15 minutes, combines error logs and records Lovable publishing events. Cloud Looking glass equivalent: Tests cloud provider availability and network performance rather than documenting these application integrations.
Model security oversight
SaaS Sentinel: includes AI model inventory, lifecycle tracking and retirement alerts under security and compliance, clearing alerts only after successful re-scans verify resolution. Cloud Looking glass equivalent: Not stated publicly
Invoice cost allocation
SaaS Sentinel: accepts forwarded supplier invoices and direct PDF uploads, uses AI to extract invoice details and line items, and requires user-confirmed project allocations before recording costs. Cloud Looking glass equivalent: Not stated publicly
Licence profitability
SaaS Sentinel: calculates cost per licence, break-even licence counts and profit margins per application and customer. Cloud Looking glass equivalent: Not stated publicly
Capacity planning reviews
SaaS Sentinel: reviews seven days of project readings weekly and provides plain-English summaries, upgrade recommendations with costs and recent trends. Cloud Looking glass equivalent: Not stated publicly
Where Cloud Looking glass is stronger
Independent cloud testing
Cloud Looking glass: tests availability across 26 providers using globally distributed agents and redundant accounts, with full service testing currently limited to Amazon Web Services us-east-1 and networking tests across 25 other providers.
SaaS Sentinel: Checks applications and their Supabase projects and links provider status to dependent applications.
Network investigation
Cloud Looking glass: offers live network tests within and between cloud locations, across providers and towards a user's internet connection.
SaaS Sentinel: Checks website availability and response times every 15 minutes.
Manual outage verification
Cloud Looking glass: manually reviews detected events, compares failures across accounts and checks provider reports or support channels before documenting confirmed outages.
SaaS Sentinel: Automatically opens public status incidents after two failed or slow checks and resolves them after recovery, with manual updates available.
Common questions
- Are these products checking my applications or the underlying cloud?
Cloud Looking glass: Cloud Looking glass tests underlying cloud availability and network performance across providers, with full service testing currently live in Amazon Web Services us-east-1.
SaaS Sentinel: SaaS Sentinel checks your applications and connected Supabase projects every 15 minutes, records Lovable releases and links provider status to affected applications.
- How does AI model monitoring differ from cloud availability monitoring?
Cloud Looking glass: Cloud Looking glass measures cloud availability through repeated tests and manually verifies outages; AI model monitoring: Not stated publicly.
SaaS Sentinel: SaaS Sentinel includes bounded weekly scans of linked source-code repositories under security and compliance, identifying model references rather than measured production usage and tracking lifecycle events in application history. SaaS Sentinel synchronises OpenAI retirement dates when supplied, uses administrator-maintained dates for other providers, and clears retirement alerts only after a successful re-scan verifies removal or that the retirement condition no longer applies.
- What pricing and trial information can I use to budget?
Cloud Looking glass pricing and trial terms: Not stated publicly. SaaS Sentinel publishes prices at https://saassentinel.co.uk/pricing and offers a 14-day no-card trial, with Starter costing £18/month for 5 projects before tax.
