Focused on practical screening workflows for investors who want repeatable market context.
Searchers often land on Finviz ETF heat map pages when they want a fast visual scan of fund performance. That is a valid starting point. It is not the same problem as building a repeatable ETF research workflow with fees, liquidity, holdings, and exposure compared every week.
This article compares three surfaces honestly:
None of these are recommendation engines. Each answers a different question.
Finviz and similar tools popularized tile maps where fund squares show category groupings and color encodes recent performance. Tile size may reflect assets or another scale variable.
Strengths:
Limits:
Use Finviz-style maps when you want a market snapshot, not when you need a documented fund selection memo.
An ETF screener applies filters and sorts to a universe: expense ratio ceilings, AUM floors, yield bands, asset class, and more. Output is a table you can revisit.
Strengths:
Limits:
Buydy's live ETF screener workflow targets this layer: stable universes, saved filters, and honest data gaps.
A percentile ETF heat map (in development) aims to combine screener shortlists with side-by-side relative context: display percentiles vs a peer set, raw values for verification, blank cells when data is insufficient.
That sits between:
It supports questions like: "Among US dividend ETFs, which names combine acceptable fees, liquidity, and yield relative to peers?" without treating one return color as the answer.

| Question | Finviz-style map | ETF screener | Planned percentile ETF map |
|---|---|---|---|
| Primary output | Colored performance tiles | Filtered sortable table | Multi-metric comparison grid |
| Best for | Quick visual scan | Building and refreshing shortlists | Ranking finalists across metrics |
| Fees / holdings | Secondary | Visible as columns | Planned alongside percentiles |
| Repeatability | Snapshot-oriented | Strong with saved filters | Strong when peer set is stable |
| Buydy status | External tool | Live | In development |
This avoids two traps: pretty tiles without fund structure, and long screener lists without priority.
Partially, with different emphasis. Buydy is built for repeatable research workflows: screener persistence, stock percentile heat maps, indexes, and digests in one membership. It is not a Finviz clone and does not currently offer Finviz-style ETF performance tiles or live ETF fund percentiles.
If you need a free performance map for a quick scan, Finviz may remain useful. If you need weekly fund comparison discipline, start with the screener and comparison guides inside Buydy.
It is a visual map of ETFs where layout and color emphasize performance and scale in a snapshot view. It is popular for scanning what moved, not for full fund due diligence alone.
Use a screener when you know your mandate filters. Use a performance map when you want a quick visual scan of market leadership. Most serious workflows use both at different stages.
Not directly. Buydy focuses on persistent screening, percentile stock heat maps, and planned ETF comparison workflows rather than free performance tile maps.
ETF fund percentile comparison is in development. Use the live ETF screener and comparison guides until it ships. Check ETF heat map landing for product direction.
