    7 Free ZoomInfo Alternatives in 2026 (Real Limits)

    ZoomInfo Lite gives you 10 credits a month. Here are 7 free ZoomInfo alternatives with their actual 2026 limits and the volume threshold a real campaign needs.

    Ashish RathodHead of GTM·12 min read·August 8, 2026

    Ten credits a month. That is ZoomInfo Lite, the permanent free tier, and it is enough to download ten contacts before you are done for the month. If you are hunting free ZoomInfo alternatives, the useful answer is that no free plan in this category will run your outbound, and the ones worth your time are the ones with enough allowance to test data quality properly. Apollo and Clay lead on free credit volume at 100 a month. InboundLabs is free to start. LeadIQ, Lusha, and Wiza sit in the 20 to 50 range.

    Here is exactly what each free plan gives you in 2026, what it withholds, and the volume threshold that separates a usable free tool from a demo.

    A free ZoomInfo alternative is a B2B contact database with a permanent free tier, not a time-limited trial. The distinction matters: permanent tiers let you test accuracy on your own list repeatedly, while trials expire in days and pressure you into a decision before you have real data.

    What ZoomInfo Lite actually gives you

    Start with the baseline, because most articles on this keyword do not state it plainly. ZoomInfo Lite is a genuine permanent free tier. No credit card, no expiration, no annual commitment. You get 10 monthly credits for downloading verified contact records, the Chrome extension, HubSpot integration, and WebSights Lite for identifying companies visiting your site, capped at 10 visitor reveals a day.

    Two limits deserve attention. Only three employees from a single company can use Lite at the same time, so a team cannot quietly run on it. And the Community Edition variant raises the allowance to 25 credits in exchange for sharing contacts from your own email account, which is a data trade rather than a free upgrade. Decide whether that is acceptable before you enable it. There is also a paid-platform trial, commonly reported as running 48 hours to 7 days with roughly 200 bulk credits. It ends automatically.

    For context on what you are being funnelled toward: paid ZoomInfo starts around $14,995 a year for Professional with three seats and 5,000 credits, Advanced sits near $24,995, and Elite from $39,995. Vendr's marketplace data puts the average contract at $33,500 across 1,012 deals. Ten credits a month is a data-quality sample, not a prospecting plan. Use it that way and it is genuinely useful.

    1. InboundLabs

    Best free starting point for testing on a real list. InboundLabs is free to start, and the reason to begin here is what you are testing for. Free tiers exist to answer one question: does this database hold verified, deliverable records for my specific segment? InboundLabs runs 280M verified B2B contacts with email data held to 98% deliverability and verified direct dials rather than switchboard numbers.

    Buyer intent signals sit alongside firmographic filters even at the entry level, so you can see whether the prioritisation layer works on your accounts rather than taking it on trust from a demo. When you do move to paid, there is no annual contract, which removes the commitment risk that makes free-tier testing feel high stakes elsewhere. The one caveat: it is newer than the incumbents, so procurement teams scoring vendor age will ask about it.

    2. Apollo.io

    Highest free credit volume alongside Clay. Apollo restructured its free tier in late 2025 down to 100 email credits per month, which is still the most generous mainstream free plan for contact data. You also get access to the sequencer and the extension, so you can run a small real campaign end to end rather than just pulling records.

    Paid plans start at $49 per user per month on annual billing ($59 monthly) with 30,000 credits granted upfront for the year, rising to $79 for Professional with 48,000 credits and $119 for Organization with a three-seat minimum. Verification matters here more than anywhere else on the list. Apollo advertises accuracy near 91% while raw exports commonly deliver at 65% to 70%, with bounce reports from 15% to 38% on unfiltered pulls. On a free tier that means your 100 credits may return meaningfully fewer usable addresses, so always apply the verified filter.

    3. Clay

    Best free tier for testing coverage on hard segments. Clay's free plan gives 100 credits a month with access to most providers in its marketplace. Because Clay runs waterfall enrichment across 150 or more providers, this is the single best way to find out whether your difficult segment is reachable at all before you pay anyone.

    Understand the credit maths. A single-provider email lookup commonly costs 2 to 3 credits and a three-provider waterfall 4 to 8, so 100 credits is roughly 15 to 40 enriched records depending on depth. Paid plans are Launch at $185 a month with 10,000 credits and Growth at $495 with 25,000, with CRM sync gated to Growth. Credits go fast on waterfalls, the learning curve is steep, and the paid entry is expensive.

    4. LeadIQ

    Best free tier for testing CRM sync. Free gives 1 user and 50 Universal Credits a month. That is 50 emails, or 5 phone numbers, or a mix, since phones cost 10 credits against 1 for an email. The reason to use this free tier specifically is the integration. If your evaluation question is whether records land clean in Salesforce or Outreach without manual cleanup, LeadIQ's free plan answers it, and no other free tier on this list does that as well. Paid Pro starts around $200 a month for 200 monthly credits shared across up to five users. Credits do not roll over, and paid pricing is opaque.

    5. Lusha

    Simplest free tier for a quick accuracy check. Free gives 40 credits a month with the browser extension, which is enough to spot-check accuracy across a handful of target accounts in an afternoon. Paid starts at $37.45 per user per month on annual billing ($49.90 monthly) with 4,800 credits a year, scaling through Pro at $52.45 to $174.95 and Premium from $299.95 monthly. Phone reveals cost several credits each, so budget the free allowance accordingly. Independent 2026 testing found strong accuracy on records returned, with match rates varying noticeably by segment.

    6. Wiza

    Best free tier for testing real-time verification. Free gives 20 email credits and 5 phone credits a month. Small, but the mechanism is what you are testing: Wiza verifies each address at the moment of reveal rather than serving a pre-collected record, and commonly reports 90% to 95% deliverability. The catch to know before investing evaluation time: Wiza's bulk export workflow requires a separate LinkedIn Sales Navigator subscription at roughly $99 to $149 a month, which is not included in any Wiza plan. Paid tiers are $83 monthly on annual billing for Email and $166 for Email plus Phone, so the true cost lands between $182 and $232 per rep.

    7. ZoomInfo Lite

    Worth using purely as a data-quality benchmark. Ten credits a month will not run anything, but ZoomInfo holds the deepest US contact and firmographic dataset, so those ten records are a useful accuracy reference point against which to score everyone else. Use it deliberately. Pick your ten hardest accounts, pull those records, and treat the result as your ceiling for what is knowable about that segment. If a cheaper tool matches it on your ICP, you have your answer. The limits are 10 credits monthly, the three-employee cap, and the Community Edition requirement to share your own contacts.

    The InboundLabs Free Tier Floor

    Free-tier roundups usually rank on generosity. That is the wrong axis, because none of these plans is generous enough to matter operationally. The InboundLabs Free Tier Floor is the monthly verified-contact volume below which a free plan cannot run a campaign, only test one. For a single rep running normal outbound, that floor sits at roughly 250 verified contacts a month.

    Every free tier in this category sits below the floor. That is the design, not a bug. Use them to test accuracy, never to run pipeline.
    The Free Tier Floor: free allowances all sit below the roughly 250 verified contacts a rep needs monthly

    The arithmetic is simple. A single campaign of 250 contacts, sent across a month with follow-ups, is a modest workload for one SDR. The largest free tier on this list gives 100 credits, and credits are not verified contacts, because match rates and verification failures reduce the usable number further. ZoomInfo Lite's 10 credits is 4% of the floor. Two rules follow, and they change how you should spend your evaluation time:

    1. Stop optimising for free volume and start optimising for free signal. The right question is not which plan gives most credits, but which plan lets you answer whether this data works on your segment fastest. Forty credits spent on your forty hardest accounts tells you more than 100 credits spent on easy ones.
    2. Run every free tier on the same list, then buy on cost per verified record. Free plans exist to convert you. Use them to generate a fair comparison instead, and let the paid decision follow from measured match and bounce rates.

    How to run a proper free-tier evaluation

    1. Pick 20 accounts you consistently struggle with. Not a clean sample. The awkward segments where your current tool returns blanks are where free tiers reveal real differences.
    2. Sign up for four or five free plans and pull the same 20. Apollo, Clay, Lusha, LeadIQ, ZoomInfo Lite, and InboundLabs all support this within a small credit budget.
    3. Log match rate per field. Verified email, mobile, and the firmographics your routing depends on. Overall match rate hides the field you actually need.
    4. Verify every returned email independently. This is the step that separates advertised accuracy from deliverable accuracy, and it is where free-tier evaluations usually change someone's mind.
    5. Divide the paid plan cost by projected verified records. Rank on cost per verified record at your real volume, not on the free allowance that got you in the door.

    Where InboundLabs fits

    The point of a free tier is to answer one question honestly: does this data work on my list? InboundLabs is free to start, with 280M verified B2B contacts, 98% deliverability on email data, verified direct dials, and buyer intent alongside firmographic filters. When you move to paid there is no annual contract, so the decision you make after testing stays reversible. See how InboundLabs finds verified contacts instantly at inboundlabs.app.

    The takeaway

    ZoomInfo Lite is a real free tier and a genuinely useful benchmark at 10 credits a month. It is not a prospecting plan, and neither is anything else on this list. Every free tier in this category sits below the Free Tier Floor by design. Use them the way they are actually valuable: run your twenty hardest accounts through four or five of them, verify the results independently, and buy on cost per verified record. Pick your 20 hardest accounts and run them through every free tier this week.

    Frequently asked questions

    Is ZoomInfo free?

    ZoomInfo Lite is a permanent free tier with 10 monthly credits, the Chrome extension, HubSpot integration, and WebSights Lite capped at 10 visitor reveals a day. No credit card and no expiration. Only three employees from one company can use it simultaneously, and paid plans start around $14,995 a year.

    What is the difference between ZoomInfo Lite and Community Edition?

    Lite gives 10 monthly credits with no obligations. Community Edition raises the allowance to roughly 25 credits in exchange for sharing contacts from your own email account. That is a data trade rather than a free upgrade, so check your company's policy before enabling it.

    Which free B2B database gives the most credits?

    Apollo and Clay both give 100 credits a month, the highest mainstream free allowances in 2026. LeadIQ gives 50, Lusha 40, Wiza 20 emails plus 5 phones, and ZoomInfo Lite 10. InboundLabs is free to start. None of these is enough to run a real campaign.

    Can I run outbound entirely on free tiers?

    No. A single rep running normal outbound needs roughly 250 verified contacts a month, and the largest free tier here provides 100 credits, which converts to fewer usable records after match and verification losses. Free tiers are accuracy tests, not prospecting plans.

    Is ZoomInfo's free trial different from ZoomInfo Lite?

    Yes. Lite is permanent with 10 monthly credits. The paid-platform trial is time limited, commonly reported at 48 hours to 7 days with roughly 200 bulk credits, and it ends automatically. Use the trial for a burst of volume testing and Lite for ongoing spot checks.

    How should I test a free tier properly?

    Run the same 20 difficult accounts through every free plan, log match rate per field rather than overall, then verify each returned email independently. That last step is what exposes the gap between advertised accuracy and deliverable accuracy, and it usually decides the purchase.

    What is a good bounce rate to aim for?

    Under 2% on hard bounces protects sender reputation. Above 5%, mailbox providers start throttling and the damage follows your domain into every future campaign. That threshold is why verified match rate matters far more than free credit volume when comparing tools.
