holidays.rest

holidays.rest provides the most accurate and comprehensive holiday data delivered at blazing speed for customers at any scale. Cover national, public, and religious holidays for 190+ countries in milliseconds with our RESTful API. We take pride in delivering authentic, accurate data. Our API exclusively offers real historical information without artificial records. For example, it recognizes that October 3rd wasn’t German Unity Day in 1985 because Germany wasn’t unified at the time—something many other APIs fail to account for. We also don’t provide fictional data. The United Nations recognizes 195 countries, with an additional 9 partially recognized states. Unlike others, we don’t exaggerate by claiming to cover 250 countries. Our pricing is straightforward: all plans give you full access to the capabilities of our API, without restrictions on parameters or features. No hidden limitations—just simplicity.

Shiplight

Shiplight brings autonomous AI agents to quality-assurance workflows, generating, running, and maintaining end-to-end tests so development teams can “ship fast and break nothing.” It enables full test coverage in just days, with no scripting required; test flows are auto-generated from product flows, documentation, support tickets, and more; parallel execution and smart caching deliver fast, reliable feedback; and visual editors and natural-language prompts mean non-coders (product managers, QA analysts) can create, review, and manage tests without writing scripts. The underlying agent “learns” the application’s behavior over time, visually navigating UI elements, clicking through flows, filling in forms, and adapting to UI changes, so that maintenance burdens and flaky tests are dramatically reduced. It fits into existing CI/CD pipelines, supports an agent-driven execution layer.

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 users

AxioMyth

AxioMyth is an AI-assisted, no-code test automation platform that verifies cross-system workflows on one visual canvas. Most testing tools stop at the browser. They confirm the screen looked right but never check whether the database updated, the email sent, or the API returned the correct state. AxioMyth tests the whole workflow. Browser steps, API calls, database queries, and third-party checks live on one canvas with branching and parallel execution. The test fails where the system fails, not just where the screen looks wrong. When tests fail, the AI Helper diagnoses the root cause and proposes a fix. It never modifies tests on its own. Every suggestion requires human approval with a full audit trail. Every customer gets a dedicated database with encrypted credentials and server-side role-based access control. Built for QA engineers, SDETs, and engineering managers who need confidence that a green test suite means a working system.

ReqKey

ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.

EventSend

My Tiny Rocket LLC

EventSend is event tracking and alert routing for a small SaaS team - the two halves of knowing what your product is doing. Send an event with one HTTP POST from any language, or write no code at all: paste one URL into Stripe, GitHub or Vercel and their webhooks arrive formatted and deduplicated. Every event lands in a live feed you can search and filter by name, level, source, customer and date, with operational analytics over it: volume, error rate, delivery health per destination, and twelve months of history on every plan. Filter to one customer and you have their timeline. Then rules route the events that matter to where your team already is: Slack, Discord, Telegram, a signed webhook, or a push notification on your phone, with retries and backoff, circuit breakers around a failing destination, and a log of every attempt. Your AI assistant can read the same history and tell you what happened. Free forever for 2,500 events a month, plans from $12.
