Hooksbase
Hooksbase
Hooksbase is event infrastructure for AI agents. It ingests events over four channels — HTTP webhooks, email, hosted forms, and scheduled cron — verifies and persists each one, then routes, transforms, and delivers to five typed outbound destinations: HTTP, AWS SQS, AWS EventBridge, GCP Pub/Sub, and S3-compatible storage. Delivery includes retries with exponential backoff, strict FIFO ordering, a dead-letter queue, and deterministic replay from persisted dispatch snapshots, so an agent can recover events it missed. Five verified provider packs (Stripe, GitHub, Clerk, Slack, Resend) validate signatures on ingest; outbound signing is Standard Webhooks-compatible with rotation overlap. Free starts at 5,000 deliveries/month with no card; Starter $25, Pro $79, and Business $249 add transforms, FIFO, and higher volume.Starting Price: $25/month -

EventIn
V-CUBE
In online events using the conventional web conferencing system and webinar system, it was difficult to promote interaction between participants and exhibitors, and to deepen the connection between them, such as forming personal connections and acquiring customer information. It is difficult to produce the world view of the event and the prosperity of each booth, and it is not possible to activate matching and interaction between companies and participants. It takes time and cost to aggregate the behavior data of participants, it is not possible to provide it to exhibiting companies in a timely manner, and the value of the event is halved. There is little participant information that can be obtained, for example, even if only the viewing history of the webinar is passed, you do not know which user to approach. -

MergeMe
MergeMe
MergeMe mirrors GitHub pull requests and GitLab merge requests into Slack as a single, updating notification card per PR/MR. Unlike the official GitHub or GitLab Slack apps, which post a new message for every event, MergeMe edits one message in place as status changes (opened, in review, approved, merged). Review comments appear as thread replies under that card. Supported code hosts: GitHub, GitLab, and GitLab self-hosted. One workspace can connect multiple git sources at once. Route each repo or project to its own Slack channel, map GitHub/GitLab usernames to Slack users so @mentions actually ping reviewers, and use label-based routing to send bugs, features, and docs work to different channels. Setup takes about five minutes: connect Slack, connect your git provider (OAuth, GitHub App, or webhook URL for self-hosted), then add channel mappings. MergeMe uses webhook payloads only - it does not read your private source code. Free Hobby plan: 1 channel mapping, 5 usersStarting Price: £5 per developer seat / month -
