Lightweight & safe
Fast, isolated, and unbreakable. Wakeline loads quickly, keeps its styling entirely separate from yours, and is built to never break your app — if something's off, it simply stays out of the way.
Quick to load
A small footprint that won't slow your app down.
Fully isolated
Wakeline's styling never leaks into — or clashes with — yours.
Fails safe
If anything ever goes wrong, your app keeps working as normal.
Live in three steps.
It loads quietly
In the background, and fast.
It stays separate
Your design is left untouched.
It never breaks you
Safe by design.
What "never break the host app" looks like in practice.
An onboarding SDK earns trust by being boring under failure. These are the design choices, shown against the incidents they prevent.
Async by default
The snippet loads wakeline.js asynchronously. Your page renders at full speed whether Wakeline is up, slow, or unreachable — the SDK is never on your critical path.
Styles in a sealed box
Guides render inside Shadow DOM: your CSS cannot deform a guide, and guide styles cannot leak into your app. Your button stays your button.
Failure means silence
Config fetch fails? Selector missing? SDK errors? The rule is uniform: do nothing visible. Users see your app, not an error state from a guidance layer.
Guides degrade per step
A step whose anchor disappeared skips or waits — your choice — instead of stranding the tour. Breakage becomes a funnel dip you notice, not an incident your users report.
What to expect: The honest promise: when Wakeline has a bad day, your users cannot tell. The SDK stays small, loads off the critical path, and treats invisibility as the correct failure mode.
When not to use lightweight & safe.
No pattern fits every job. Here’s where we’d point you at something else — sometimes ours, sometimes not.
Synchronous, blocking rollouts
If a message legally must render before the user proceeds (consent walls, ToS gates), build it in your app. Wakeline's fail-open design — app first, guides second — is the opposite contract, on purpose.
As uptime monitoring
Silent failure protects users but can hide problems from you. Watch your guides' trend charts — a flatline is your alarm — rather than assuming silence means health.
How big is the SDK?
Small enough to be a rounding error in a modern bundle, and it loads asynchronously, so size never blocks first paint anyway. The design bias is ruthless: guidance is a layer, not a platform runtime.
Can Wakeline's styles conflict with mine?
No — rendering happens in Shadow DOM, isolated in both directions. Your global CSS resets cannot break a modal; a guide's fonts cannot bleed into your tables. Theme-scoped custom CSS targets only widget classes.
What happens if the Wakeline API is down?
Nothing your users see. The SDK fails silently — no guides render, no errors surface, your app behaves as if Wakeline were not installed. Events queue and recover where possible.
Does it affect our Core Web Vitals?
The async snippet keeps it off the render path, so LCP and FCP are untouched. Guides render after the page is interactive — by design, since guidance about a page that has not painted helps nobody.
Is the SDK safe to run alongside other scripts?
Yes — it keeps to itself: no globals beyond its own namespace, no patching of your frameworks, Shadow-DOM rendering, and event listeners scoped to its widgets. Analytics tools, chat widgets, and error trackers coexist untouched — Wakeline neither reads nor alters what they do.
