Restored foundation
Original 2026-08-22 browser-local tool core
This route comes from the previously merged 434-tool Solarc library. It uses browser-native calculation or transformation logic and does not pretend to be an external OSS engine.

No forced upsell. This atomic utility has no direct paid-product dependency, so the next step stays inside the free-tool library.
Useful? Send the exact tool, not the homepage.
Every share opens this free, no-signup route directly. Channel links carry campaign tags so distribution can be measured.
Publisher distribution · free embed
Put this working tool on your own site.
No signup, API key or approval queue. Paste the snippet into a blog, knowledge base, client portal or resource page. It lazy-loads, keeps a fixed-height fallback, and auto-sizes when your CMS allows the included resize script. Keep the visible Solarc Labs attribution link with the embed.

Evidence & provenance
What you can verify on this route
Solarc exposes the utility's purpose, implementation provenance and limitations instead of manufacturing first-person experience or pretending that E-E-A-T is a citation switch.

Truth boundary
Generated, transformed or validated output still needs review before production use. Passing a syntax or format check is not a security, compliance or semantic-correctness guarantee.
Citation boundary: evidence improves inspectability and citation-worthiness; it does not guarantee ranking or citation by Google, ChatGPT, Gemini or any other search or AI system.

Turn this atomic tool into a reusable workflow.
Start the visual route builder with this tool already selected, then add the next steps you actually need. The builder stores route slugs only — never your pasted input, uploads or generated results.

What should you do next?
Recommendations are ranked from real curated workflow adjacency first, then same-job-family fallback. No fake ratings, usage counts or behavioural profiling decide this list.

Answer-first guide
Use the tool first. Pay only when the workflow earns it.
No fake gate before value. The free route answers the immediate job; the paid route is for evidence, implementation or support.
What does UTM URL Builder do?
Build a URL with common UTM campaign parameters without sending it anywhere.
Is UTM URL Builder free to use?
Yes. The browser-tool path is free and does not require signup. Paid work is for evidence, implementation help, larger scope or human review rather than hiding the basic utility behind a gate.
When should I move beyond the free UTM URL Builder?
Stay on the free path for one-off work. Consider a paid proof only when the task becomes repeated, higher-value, collaborative, evidence-sensitive or important enough to need a bounded support path.
Free path + three paid steps
Start at $0. Escalate only when there is evidence.
Free
$0
One-off browser use with no signup. Keep using this route when it already solves the job.
- Immediate tool access
- No signup gate
- Stay free for one-off use
First Paid Proof
$5
A bounded fit / no-fit check plus one concrete blocker or next step.
- Small paid commitment
- One concrete finding
- No forced subscription
Focused Diagnostic
$50
For recurring or higher-value work that needs a few evidence-backed findings and a clear action path.
- Up to three findings
- Prioritised next actions
- Human-reviewed scope
Action Pack
$99
For a workflow that has earned a deeper review, implementation plan or acceptance checklist.
- Up to five prioritised actions
- Acceptance checklist
- Implementation handoff path
These are portfolio-default proof/diagnostic steps, not a promise that every workflow has identical implementation scope. The linked product page remains authoritative for exact scope, availability and checkout terms.

Shareable utility
Finish the job, then pass the tool to the next person who needs it.
The free result stays useful on its own. Sharing points to the tool page only; unmatched commercial intent stays in the free-tool network instead of being forced into a generic product directory.
Publisher / community kit
For a README, newsletter, blog, forum answer or resource list: copy a clean production backlink without copying the visitor's input or result.
Attribution uses the tool slug and CTA placement only. Share and publisher links use the canonical production URL. The growth event contract never includes input text, uploaded-file contents or generated output.
Demand → exact tool → next useful action
Send people to this exact job, not the generic tools homepage.
Copy a channel-attributed deep link to UTM URL Builder. Every link lands on this exact tool; the canonical page stays clean for search engines, and no visitor input or result is placed in the URL.

Can the value land before the explanation?
Use this as a silent-demo production template for Shorts, Reels, TikTok, a launch GIF or a community post. The first second should show the tension or transformation — not a logo, setup screen or narrated promise.
Vertical capture · 9:16
405×720 reference · 10s
Keep the actual input, primary action and proof result inside the central vertical frame; browser chrome is not the product proof.
Append ?wow=1 for the deterministic capture helper. It injects input only when an owned synthetic fixture exists, then captures the real tool action and result.

blank starting point → usable generated artefact
0–1 second · hook
Show an empty/unfinished starting state next to the kind of artefact the tool will produce.
1–6 seconds · action
Use UTM URL Builder with minimal synthetic inputs and keep generation time out of the edit where possible.
6–10 seconds · proof
Finish on the usable artefact itself. Make clear when the output is a draft, template, or starting point rather than authoritative proof.

Try UTM URL Builder free — no signup.
Safety / truth boundary: use synthetic or public-safe demo data only. Never show secrets, private customer material, fabricated metrics or a pass/certification claim the tool does not actually produce. This template improves demonstrability; it does not promise reach or virality.
