Scout Review

Written by AI from measured evidence, scored out of 100.

Le Gantt is a focused tool that solves a real problem: project managers who live in Trello or Basecamp but need Gantt charts. The free Trello Power-Up and 14-day Basecamp trial lower the barrier to entry, and the feature set — auto-scheduling, critical path, baselines, milestones — is solid. The landing page is clean and the desktop performance is excellent. But mobile speed lags, security headers are incomplete, and accessibility has contrast and touch target issues. There's no public documentation or help center, which is a gap for a tool with this many features. Overall, it's a competent niche product with a clear wedge, but it needs polish on the technical fundamentals to stand out against broader competitors.

Measure by measure

Usability

Free Trello Power-Up with no account required and a 14-day Basecamp trial lower the barrier. Live demo is a plus, but no public docs or help center found.

Design

Clean, modern landing page with clear platform segmentation. Emoji icons and text-heavy feature grid feel slightly generic, but overall polish is above average for an indie tool.

Speed

Desktop Lighthouse score of 98 is excellent, but mobile performance drops to 71 with a 5.3s LCP — well above the 2.5s 'good' threshold. Mobile users will feel the lag.

Security

HTTPS and HSTS are in place, but missing CSP, frame protection, and other headers. No DMARC, no public security page, and only 5/12 checklist points. Standard for an early-stage tool.

Accessibility

Lighthouse score of 92 is strong, but failing contrast and touch target audits hold it back. No accessibility statement or WCAG mention found. Responsive layout is a plus.

Growth

Real problem for Trello/Basecamp users who need Gantt views without switching tools. Native integration and free tier are concrete wedges, but the category is crowded with broader suites.

Improvement areas

Mobile performance: LCP of 5.3s is well above the 2.5s 'good' threshold; optimize for mobile users.
Security headers: missing CSP, frame protection, X-Content-Type-Options, Referrer-Policy, and DMARC.
Accessibility: failing contrast and touch target audits; no accessibility statement or WCAG mention.
Documentation: no public help center or docs for features like critical path and auto-scheduling.

Design & Usability

Le Gantt's landing page is clean and modern, with clear segmentation for Trello and Basecamp users. The design is above average for an indie tool, though the emoji-heavy feature grid feels a bit generic. Usability is a strong point: the Trello Power-Up is free and requires no external account, and the Basecamp extension offers a 14-day trial without a credit card. A live demo is linked directly from the homepage, making it easy to try before installing. However, there's no public help center or documentation, which could leave users hunting for answers on critical path and auto-scheduling. For a tool aimed at project managers, better onboarding resources would go a long way.

Speed & Security

Speed is a tale of two platforms. Desktop Lighthouse performance is excellent at 98, but mobile drops to 71 with an LCP of 5.3 seconds — well above the 2.5s 'good' threshold. Mobile users will notice the lag, which is a problem for a tool meant to be used on the go. Security is standard for an early-stage product: HTTPS and HSTS are enforced, but CSP, frame protection, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy are all missing. DMARC is also absent, and the HTTP header checklist scores only 5/12. There's no public security page, SOC 2, or bug bounty. None of this is alarming for a new tool, but it's not a selling point either.

Accessibility & Growth

Accessibility scores 92 on Lighthouse, which is strong, but failing contrast and touch target audits mean real users with low vision or motor impairments will struggle. No accessibility statement or WCAG mention was found. Growth potential is moderate: Le Gantt targets a specific niche — Trello and Basecamp users who need Gantt charts without switching tools. The free Trello Power-Up and two-way Basecamp sync are concrete differentiators. However, the category is crowded with broader suites like TeamGantt, ClickUp, and Asana. Le Gantt's wedge is deep integration, but that's a feature incumbents could replicate. The domain is only 1.1 years old, so traction is still early.

Conclusion

If you're a Trello or Basecamp user who's been squinting at cards and lists trying to visualize dependencies, Le Gantt is worth a look. The free Trello Power-Up makes it a no-brainer to try, and the Basecamp trial gives you two weeks to see if the two-way sync fits your workflow. Just don't expect enterprise-grade security or mobile performance yet. For solo freelancers and small teams, it's a practical addition to the toolkit. For larger teams with compliance requirements, you'll want to wait for more transparency and hardening.

Suggestions for improvement

Add a public help center or documentation page covering auto-scheduling, critical path, and baselines.
Improve mobile performance — LCP of 5.3s is too slow; optimize images and reduce render-blocking resources.
Implement missing security headers (CSP, frame protection, X-Content-Type-Options) and add DMARC.
Fix accessibility issues: increase color contrast and enlarge touch targets; publish an accessibility statement.
