Quick answer
Hook0 - Hook0 wins for most builders because its free tier is a more usable managed starting point, with no credit card required, broader product scope, and a clearer path to higher-volume usage when you outgrow the cap.
How the free tiers compare
These two free tiers solve the same core problem, but they differ in how much of the product you can actually use before paying. Hook Relay is narrower and more webhook-delivery focused: you get 100 deliveries per day, 3 endpoints, and 14 days of retention, which is enough for a small integration but not much else. Hook0 gives you a managed cloud service plus more account structure up front: 1 developer, 1 application, 10 event types, 10 subscriptions, 100 events per day, 7 days retention, and blocked overages. That makes Hook0 more like a small production starter, while Hook Relay is a lighter webhook inbox with better retention on the free tier. Once you pay, Hook Relay is simpler and flat-priced, while Hook0 introduces usage-based overages and multiple deployment paths.
Hook Relay vs Hook0 free tier, side by side
| Hook RelayFTV 49 | Hook0FTV 68 | |
|---|---|---|
| Free event/delivery limitDifferent unit names, but the free-tier throughput cap is the same order of magnitude. | 100 deliveries/day | 100 events/day |
| RetentionHook Relay keeps logs longer on the free tier. | 14 days | 7 days |
| Endpoints / subscriptionsHook0’s free tier also includes 10 event types and 1 application. | 3 hook endpoints | 10 subscriptions |
| Developer seatsHook0 explicitly limits the free tier to one developer. | Not stated | 1 developer |
| Credit card requiredBoth inputs explicitly say no credit card is required. | No | No |
After you outgrow the free tier
Hook Relay uses simple flat pricing after free: the first paid tier is Basic at $30/month, then Plus at $90/month. Hook0’s hosted cloud plans are usage-based with a monthly base price plus overages, starting at €59/month for Startup with €0.003 per event overage, then €190/month for Pro with €0.0001 per event overage. For small teams, Hook Relay is easier to predict and cheaper at the low end. Hook0 can become more expensive if you exceed included volume, but its overage rate drops sharply at higher tiers.
Cost at real usage
| Usage | Hook Relay | Hook0 |
|---|---|---|
| 100 deliveries/events per dayBoth free tiers cover this level. | Free (within tier) | Free (within tier) |
| 1,000 deliveries/events per dayHook Relay’s Basic plan covers up to 10k deliveries/day. Hook0 Startup includes 30,000 events/day, so 1,000/day stays within tier. | $30/mo | €59/mo excl. VAT, plus overage if above included volume |
| 40,000 deliveries/events per dayHook Relay’s Plus covers up to 30k deliveries/day, so 40k/day exceeds the listed quota. Hook0 Pro includes 100,000 events/day. | $90/mo | €190/mo excl. VAT, plus overage if above included volume |
| 150,000 deliveries/events per dayHook Relay’s provided plans top out at 30k/day. Hook0 Pro lists 100k/day included, then overage at €0.0001/event, but the exact monthly total depends on how much of the 150k/day is above the included quota. | Not supported by listed paid tiers | €190/mo excl. VAT + overage |

When to pick each one
Pick Hook Relay when…
- You want a simple webhook inbox with retries, logging, and delivery tracking, and you do not need lots of account-level structure.
- You only need a few endpoints, because the free tier includes 3 hook endpoints.
- You prefer a flat paid upgrade path once you outgrow free, since the first paid tier is $30/month.
- You care more about retention on the free tier than broader collaboration features, because Hook Relay gives 14 days versus Hook0’s 7 days.
Pick Hook0 when…
- You want a managed cloud webhook platform with replay, HMAC signatures, TLS, and dashboard/API replay tools.
- You need a free tier you can start on without a credit card, and that is explicitly stated here.
- You want a free plan that includes basic multi-object setup like event types and subscriptions, not just delivery volume.
- You expect to grow into higher-volume usage and want a pricing path with clearer scale-up options, including usage-based overage pricing.
Bottom line
For the most common builder case, Hook0 is the better free-tier starting point because it gives you a managed service, explicit no-card signup, and more structure around developers, applications, event types, and subscriptions. Hook Relay is the better pick if your main need is straightforward webhook delivery and you want a simpler, flat-priced upgrade path. If you expect to stay small and want the lightest webhook tool, Hook Relay is fine. If you want a more complete platform to grow into, Hook0 is the stronger choice.
