Novu

Novu is open-source notification infrastructure that gives engineering and product teams a single API to send notifications across In-App, Email, SMS, Push, and Chat channels. Instead of building custom delivery logic and managing multiple provider integrations, teams use Novu to define multi-step notification workflows and ship in minutes. Novu is built for developers and product teams at companies of any size - from startups shipping their first transactional emails to enterprises managing millions of notifications per month across complex, multi-tenant applications. At the core of Novu is the Workflow Engine, where teams build cross-channel notification sequences with built-in delivery logic: delays, digest aggregation, throttling, and conditional branching. Workflows can be designed visually with a drag-and-drop editor or defined entirely in TypeScript for teams that prefer a code-first approach. The embeddable Inbox component adds a real-time in-app notification center to any application in as few as six lines of code. Pre-built SDKs are available for React, Vue, Angular, React Native, and vanilla JavaScript, with customizable styling and built-in subscriber preference management. Novu's Digest Engine consolidates multiple notification events into a single message - reducing notification fatigue while keeping users informed. Combined with throttle controls, teams can prevent over-notifying during high-activity periods without losing critical alerts. The platform connects to 55+ delivery providers - including SendGrid, Twilio, Firebase Cloud Messaging, Slack, and Amazon SES - with automatic provider failover. If a primary provider goes down, Novu routes through the next active integration without any manual intervention. A No-Code Block Editor for email lets non-technical team members design and customize email templates with dynamic variables and conditional content blocks, while developers retain full access to raw HTML/CSS when needed. Subscriber preferences are enforced automatically during every workflow execution, giving end-users control over which channels and notification types they receive - improving engagement and reducing unsubscribes. Novu is MIT-licensed with 38,600+ GitHub stars and can be self-hosted via Docker Compose with full feature parity, or used as a managed service through Novu Cloud with a dedicated EU region for data residency requirements. Server-side SDKs are available in seven languages, and the platform is SOC 2, ISO 27001, GDPR, and HIPAA compliant. The free tier includes 10,000 events per month with no credit card required.

Courier

Courier is notification infrastructure for customer messaging, built for humans and AI agents. It sits between your app and every channel you send on: email, SMS, push, in-app inbox, chat, and webhooks. You send one request, and Courier works out where it goes, what it looks like, and whether the user wanted it at all. Teams use it for the messages a product has to send: onboarding, alerts, receipts, reminders, and account notices. You keep the providers you already pay for. Courier is the layer above them. • Design a message once and it adapts to each channel it goes out on, whether you build it in the visual editor or manage it as code. • Journeys handle the sequencing: waits, batching, digests, and branching on what someone does or ignores. • Add an in-app inbox to your web and mobile apps without building one from scratch. • Users set their own channel and topic preferences, so you are not fielding requests to turn things off. • When a provider fails, Courier fails over to another, and every send lands in one log with its delivery status. Everything in the product is on the API, so the same template or journey works however your team wants to build it: in the visual editor, as code, or handed to an AI agent through Courier's MCP server. Courier connects to 50+ providers, including SendGrid, Amazon SES, Twilio, Firebase, and Slack, and bills per message sent at one rate on every channel, with no per-seat fees. The free tier covers 10,000 messages a month. Twilio, Trusted Health, and Nav run their customer messages on Courier. Founded in 2019 in San Francisco, Courier came out of Y Combinator and is backed by GV, Bessemer Venture Partners, Matrix Partners, Twilio, and Slack Fund.

GitNotifier

GitNotifier connects GitHub to Slack to deliver pull request notifications as personal Slack direct messages. Rather than creating shared PR channels, it routes high-signal activity to each individual based on their role on a pull request (author, assignee, requested reviewer, or mentioned user), so engineers see only what is relevant to them. 🔔 Notification events GitNotifier reacts to review requests, assignments, review submissions (approved / changes requested), PR opened / merged / closed, and new PR and review comments. Notifications for a given pull request are updated in place as its state changes (for example, struck through when the PR is merged or closed), keeping a single current message per PR rather than a stream of separate ones. ⚡ Acting from Slack Interactive actions let users reply to PR comments, add GitHub reactions (via buttons or native Slack emoji, which mirror onto the GitHub comment), mute a PR by reacting with 🔇, and merge a ready pull request, all without leaving Slack. 🔇 Noise control Per-user mute rules cover bots, specific GitHub logins, review-requested GitHub teams, and individual pull requests. A Reviewer Comment Quiet Mode mutes reviewer-scoped comment notifications while still delivering direct @mentions. 📝 Digests and reminders Scheduled reminders (daily, weekdays, or weekly) summarize a user's assigned and review-requested open PRs at a chosen time in their local timezone. The /gitnotifier slash command provides an on-demand PR digest, mute management, PR search-and-mute by title, and account connection. Settings are managed from the Slack App Home and a web dashboard. 🛠️ Setup GitNotifier uses a GitHub App and a Slack app. GitHub accounts are mapped to Slack users for direct notifications.
