LighterPack vs Spreadsheets vs Featherline: Which Pack-List Tool Fits You?

There are roughly three serious ways ultralight backpackers track gear in 2026: a shared-link tool like LighterPack, a DIY spreadsheet, or a modern app like Featherline. Each has a specific tradeoff profile and a specific kind of hiker it serves well. None of them is the right answer for everyone.

This is a working hiker's comparison, written by people who have used all three across multiple thru-hike planning cycles. We will cover what each is good at, what each is bad at, who should use which, and the specific signal to watch for when you have outgrown one and should move to the next.

The three archetypes

LighterPack: the shared-link tool

LighterPack is the OG. Launched in 2013, it became the lingua franca of the ultralight subreddit because the share URL fits perfectly into a Reddit post and the pie chart is the universal shakedown currency. If you have ever read a r/Ultralight shakedown request, you have seen a LighterPack URL.

It is free, donation-supported, and almost entirely undisturbed by feature changes since around 2019. That stability is part of the appeal: nothing breaks, the URL you generated in 2018 still loads in 2026, and the community knows exactly how to read it. It is the COBOL of pack planners.

The DIY spreadsheet

Plenty of long-distance hikers run their entire gear life out of a Google Sheet or Excel workbook. Columns for item, brand, model, category, weight in grams, weight in ounces, cost, notes, acquisition date. Maybe a tab per trip with conditional formatting that highlights items being swapped out. The spreadsheet is infinitely flexible, costs nothing, and never loses your data to a startup pivot.

The downside is that you have to maintain it. Adding a new pack config means copying a tab, manually re-entering changes, re-computing every category total. Sharing means generating a public link, hoping the formatting holds up on someone else's screen, and accepting that Reddit will treat it as less canonical than a LighterPack URL.

Featherline: the modern app

Featherline is a free, mobile-native pack planner with a persistent gear library, weight breakdown by category, cost-per-ounce tracking, one-tap LighterPack import, an AI gear-swap that knows what cottage brands actually make, and a public share URL designed for Reddit and Discord. It is newer than LighterPack, with a smaller installed community, and the share URLs do not yet have the social weight that a LighterPack link does on r/Ultralight. That is the honest tradeoff.

Feature-by-feature

Who should use which

Use LighterPack if...

• You only have one or two pack lists you actively maintain.
• You post shakedowns regularly on r/Ultralight and the link format matters for community recognition.
• You do not care about mobile editing because you do all your planning at a laptop.
• You want the safest long-term bet on a tool that will still exist and still load your URL in five years.

Use a spreadsheet if...

• You enjoy building spreadsheets and the act of maintaining them is part of the planning ritual for you.
• Your gear life has unusual columns (you collect by year, you track multiple owners, you track recurring maintenance, whatever) that no off-the-shelf tool will model.
• You want a single source of truth that lives in your own cloud, your own backups, with no risk of a service shutting down.

Use Featherline if...

• You maintain three or more pack configs (summer overnight, shoulder, winter, fastpack, bikepack) and re-entering the same headlamp into five lists is making you grumpy.
• You do real planning on your phone, on the trail, or in the car on the way to the trailhead.
• You want AI gear suggestions calibrated to actual cottage brands (Senchi, Pa'lante, Litesmith, Hammock Gear) and not a generic LLM that recommends REI Co-op gear at every turn.
• You like dark mode, offline editing, and a pie chart that does not look like 2013.

When to switch from a spreadsheet to a tool

The signal is when you have three or more active pack configs and find yourself making the same change in multiple tabs. At that point the maintenance cost of the spreadsheet exceeds the cost of learning a tool. A persistent gear library that auto- propagates a swap (you replaced your headlamp, every pack that referenced the old one now points at the new one) is the single biggest productivity gain when moving off a spreadsheet.

The other signal is when you start carrying a phone on planning trips and a spreadsheet on mobile starts feeling like an accessibility test. Sheets is OK but cramped, Excel mobile is rough, and Numbers on iOS is fine until you try to share with an Android friend. A mobile-native tool removes that pain.

When not to use any of them

Not every backpacker needs a pack planner. If you go on one casual overnight a year with the same kit you have always used and you have no interest in cutting weight, the right tool is a checklist on the back of a receipt and a duffel bag in the garage. Pack planners are tools for hikers who want to optimize. That is a specific psychological profile, and it is fine if you are not in it. The people who would benefit most from a planner are the people already running mental math on their gear between trips.

The other case for skipping all of them is if you exclusively day-hike or run a fixed bikepacking setup that fits in two frame bags and never changes. A planner adds friction to a process that does not need it. Save the time and go outside.

How to migrate without losing data

The switching cost is the single biggest reason hikers stay on the wrong tool. Here is the lowest-friction path between each pair so you can move without retyping a year of gear.

• LighterPack to Featherline. Copy your LighterPack share URL, paste it into Featherline, one tap. Categories, item names, weights, and worn flags carry over. Re-uploading photos and any gear-specific notes is manual but only takes a few minutes per pack.
• Spreadsheet to LighterPack. No native import. The realistic path is to export your sheet as CSV and then either retype or use a community script (some hikers share Tampermonkey bulk-add scripts on r/Ultralight). Slow.
• Spreadsheet to Featherline. Export as CSV then bulk-add items into your gear library. Faster than LighterPack because the library is persistent: do it once, use across every pack.
• Featherline to LighterPack. Featherline can generate a LighterPack-compatible export so you can post shakedowns in the format r/Ultralight reviewers expect, even while you do your real planning in Featherline. This is the hybrid most active community posters land on.

The general rule: never let community recognition lock you out of the tool that fits your brain. Plan in the tool that works for you, post in the format your community expects.

Pricing reality: all three have a free path

One thing the brand-versus-brand discourse usually gets wrong: every tool here has a real free tier that covers the planning workflow for most hikers. LighterPack is free forever, with a donation prompt and no paywall on any feature. Spreadsheets are free in Google Sheets or LibreOffice. Featherline is free forever, with a $4.99/mo Pro tier that buys unlimited AI gear-swaps. Pro is optional, not a paywall around core planning, and you can also bring your own Anthropic API key to get unlimited AI without the subscription.

Translation: do not let pricing be the deciding factor. Choose by which workflow fits your brain, not which icon costs fewer dollars. The dollars are roughly zero on every path.

Where Featherline still loses to LighterPack

Two places, honestly. First, social weight on r/Ultralight: a LighterPack URL is the default expected format for shakedown requests, and a Featherline URL is still novel enough that some reviewers will ask you to also post a LighterPack version. Second, longevity track record: LighterPack has been around for over a decade. Featherline launched in 2025. We think we are built to last, but ten years of uptime is the kind of trust you earn, not the kind you claim.

The good news on both: Featherline has one-tap LighterPack import, so even if you primarily plan in Featherline you can export to LighterPack for community shakedowns without re- entering anything. And our share URLs are stable, with a clean public format that does not require an account to view.
