There is no single best Solana rug checker: RugCheck gives the most detailed single token report, Bubblemaps is best for seeing which top holders are linked, GoPlus and DexScreener give a quick look at a token's settings, and Before It Rugs grades new coins A to F and publishes how those grades turned out. None of them can tell you a coin is safe, and of the eight we compared, only one publishes a measured record of its own accuracy.
We run Before It Rugs, so read this knowing we are one of the tools in the table. Every claim about another tool comes from that tool's own website or documentation, checked on 26 October 2026. Where something isn't stated there, we say so. We use RugCheck and DexScreener data in our own grades, and we are not affiliated with any tool on this page.

"Not stated" means we found nothing on the tool's own site or in its docs on 26 October 2026. "Needs wallet" means to look up a token, and "Cost" is the cost of checking one on the website. Some of these sites offer wallet features such as swaps, but checking a coin never needs a wallet. Be wary of any checker that asks for one.
RugCheck
RugCheck's report shows a risk score, a list of risks, and tabs for markets, insiders, holders, and lockers and liquidity, including mint authority, the creator's balance and the share of liquidity locked. Its API docs say the score sums the risks it finds on a 0 to 100 scale where lower is safer: under about 21 is Good, 21 to 40 Warning, above 40 Danger. It also detects insider networks, wallets that trade or pass tokens between themselves.
Reports are free to read with no sign-in, and the API has a free tier, then plans from $40 a month. Creators can pay 150 USDC for a verified badge, which proves who made the token. It is not a safety rating. RugCheck says it has no token of its own and never adjusts a score for a single project.
Best for: the deepest free report on one Solana token. Our guide to reading a RugCheck report goes field by field.
Solsniffer
Solsniffer gives each token a Snifscore out of 100 and marks each check as a risk or a pass: mint and freeze authority, liquidity burned or locked, the top 10 and 20 holders, metadata, fees and the token's age. Its guide says it uses more than 22 indicators and data from several providers. A holder analysis groups the top 50 holders into clusters. Scans are free to view with no wallet, and the API has 100 free calls a month, then plans from $47.
Best for: a second score made a different way to RugCheck's.
Token Sniffer
Token Sniffer's API documentation lists 16 chains, including Solana, with pump.fun, PumpSwap, Raydium, Orca and Meteora supported. It compares contract code with more than 10,000 known scam patterns and flags impersonators and tokens with phishing links in their names. Its Smell Test score is best at 100 out of 100. The API costs $99 a month. Its main website showed a bot check on 26 October 2026, so we couldn't confirm whether the web check is free.
Best for: tokens on several chains, and spotting known scam code.
GoPlus
GoPlus has a free web check for Solana tokens with no sign-in. Instead of a grade, it lists risky items and items needing attention: mint and freeze powers, whether the program can be closed or balances changed, transfer fees, transfer hooks, mutable metadata, the top 10 holders and the pools. Its Solana check is labelled beta. GoPlus says DexScreener's security checks are built on its API.
Best for: a plain read of a token's settings, especially Token-2022 tokens with fees or hooks.
De.Fi Scanner
De.Fi Scanner's FAQ lists Ethereum-style chains, and its scanner page now adds Solana. On a Solana token it shows high-risk items, a Safety Score out of 100, more than 20 named checks, the top 10 holders and a liquidity analysis. The basic version works as a guest. Its separate Shield tool, for revoking approvals, asks for a wallet.
Best for: each contract check spelled out, with a PDF. On the established token we tried, its liquidity section showed no data, so check liquidity elsewhere.
Bubblemaps
Bubblemaps draws a token's top 250 holders as bubbles, with lines where wallets have sent tokens to each other, so you can see when several "different" holders are probably one person. Its score runs from 0 to 100, where higher means the supply is more spread out, and its wiki says it only counts clusters Bubblemaps detects. The map is free to view without logging in. A few extras, such as maps of the top 1,000 holders, need its $BMT token.
Best for: linked wallets and holder concentration. Here it beats every other tool on this page, ours included. See how to read Bubblemaps.
DexScreener's audit panel
Every DexScreener token page has an Audit panel. On the Solana tokens we checked, it showed whether the token is mintable or freezable, with a warning that the data comes from external auditors, may not be fully accurate and isn't validated by DexScreener.
Best for: a first glance while you are on the chart. Remember that boosts are paid promotion, not a sign of quality.
Before It Rugs
We grade every new Solana memecoin we find from A to F. Each warning sign adds points, and since 26 October 2026 the points depend on the coin's stage: still on a launchpad curve such as pump.fun's, or already on an open pool. Every point comes with a plain-English reason, and the methodology page sets out every rule. It is free and never asks for a wallet.
What we add is a record. The scorecard shows how often coins with each first grade collapsed within a day, misses included, with grades from earlier rules kept apart. What we don't do: we are Solana only, our token data comes from RugCheck, so we are not an independent read of it, and we don't draw holder maps. You can check any coin here.
Which to use when
- One coin, five minutes: RugCheck for the report, then Bubblemaps for the holders.
- A coin minutes old: our rug check, which weights signs by launch stage.
- A token with odd fees or settings: GoPlus or De.Fi.
- Not on Solana: Token Sniffer, GoPlus or De.Fi.
Whichever you use, read the reasons, not just the score. For a full routine, see how to tell if a Solana token is a scam.
What is the best free Solana rug checker?
For a single detailed report, RugCheck. For linked wallets, Bubblemaps. For a grade on a brand new coin with a published track record, Before It Rugs. Most people get the best result from two tools that check different things, rather than one score.
Do I need to connect a wallet to use a rug checker?
No. All eight tools on this page let you check a token by pasting its address, with no wallet connection. Some offer wallet features such as swaps or approval revoking, but checking a coin never needs one.
Why do two checkers give the same coin different scores?
They check different things and weight them differently, and their numbers don't even run the same way. RugCheck's score goes up with risk, while Token Sniffer's Smell Test and the Bubblemaps Score treat a higher number as better. Always check which way a score runs and which warnings drive it.
Can a rug checker tell me a coin is safe?
No. Checkers read what is on the blockchain. They can't see a team selling slowly, insiders using fresh wallets, or paid promotion. A clean result means the checker found none of the problems it looks for. Read can a safe-looking coin still rug?
Does Before It Rugs use RugCheck?
Yes. RugCheck reports are one of our three data sources, alongside DexScreener and GeckoTerminal. We add our own weighting by launch stage, plain-English reasons and a public record of outcomes. Because the token data is shared, use a tool with its own data, such as Bubblemaps or GoPlus, for a truly separate second opinion.
