Mercury is a business banking platform designed for startups and tech companies. Its API provides programmatic access to bank accounts, transaction history, wire and ACH payment initiation, treasury management, and multi-account management — all with no monthly fees.

Python UI framework from Google for building internal tools and AI demos. Mesop uses Angular components wrapped with a Python API and gRPC for state sync — similar to Streamlit's simplicity but with a component-based model. Designed for quickly building AI-powered demos and internal tools at Google. Open-sourced in 2024. Uses server-side rendering with incremental state sync via Server-Sent Events (SSE). Very new, 0.x, backed by Google's internal usage.

MCP server for managing Meta (Facebook/Instagram) advertising campaigns through AI interfaces, supporting campaign analysis, budget management, creative optimization, targeting, and performance monitoring across 29 tools.

Open-source observability platform (logs, metrics, traces) built in Rust as a single binary. OpenObserve claims 140x lower storage costs than Elasticsearch for similar workloads. Provides a Grafana-like UI, OpenTelemetry ingestion, SQL querying over logs, and alerting. Self-hosted alternative to Datadog/New Relic with zero licensing cost. Also offers a managed cloud version.

Local-first database sync service that syncs data from Postgres (and MongoDB, MySQL in beta) to local SQLite on mobile and web clients. Uses 'sync rules' (YAML-based) to define what data each user sees. Optimized for mobile apps with offline-first requirements.

Prismic is a headless CMS with a REST and GraphQL content API — delivers structured content (pages, articles, documents) with a Slice Machine component library for Next.js and Nuxt.

Railway GraphQL API — deploy apps, databases, and services from GitHub or Docker with zero configuration; manage environments, variables, and deployments programmatically.

Provides a clean REST API for creating, sending, and embedding e-signature workflows with a developer-friendly design emphasizing simplicity over the complexity of enterprise CLM platforms.

Data labeling and AI training data platform based on 'weak supervision' — programmatically labeling training data using heuristic functions (labeling functions) rather than manual annotation. Snorkel's approach: write Python functions that encode domain knowledge ('if text contains URGENT, label as high_priority'), then combine them with a generative model to produce probabilistic labels at scale. Used by Google, Stanford Medicine, and major enterprises to label millions of examples without per-example human labeling. Snorkel Flow is the enterprise platform; Snorkel open source is the framework.

Open-source data quality testing framework with a SQL-like YAML DSL (SodaCL) for defining checks on datasets. Soda Core runs quality checks against databases and data lakes, and Soda Cloud provides a REST API for scan management, alerting, and quality metrics. SodaCL checks include row counts, nullness, uniqueness, freshness, SQL-based custom checks, and anomaly detection.

Developer-first authentication platform offering passwordless auth (magic links, OTP, WebAuthn/passkeys), B2C user management, and B2B Organizations with SSO/SAML support — a modern, API-centric alternative to Auth0 and Okta.

Zoho Recruit REST API for cloud-based applicant tracking system. Enables AI agents to manage job postings, retrieve and process candidate records, track application stages, schedule interviews, and integrate recruiting data into HR and CRM workflows. Zoho Recruit integrates natively with Zoho CRM and other Zoho apps, making it ideal for organizations in the Zoho ecosystem.

A comprehensive Java framework for building AI applications with LLM integration, RAG pipelines, MCP protocol support, and multi-agent orchestration (ReAct, Team agents).

Lightweight job scheduling library for Node.js backed by MongoDB. Agenda stores scheduled jobs in MongoDB, supports cron expressions and interval-based scheduling, and handles job priorities, concurrency limits, and failure retries. Used when you need persistent job scheduling in Node.js without the complexity of a full distributed queue like BullMQ (which requires Redis).

Enphase solar energy system REST API for solar installers, energy management companies, and home automation platforms to access solar production data, battery storage status, consumption metrics, and system health monitoring from Enphase IQ microinverter systems through the Enlighten platform — enabling automated solar monitoring, energy management, and fleet reporting for residential and commercial solar installations. Enables AI agents to manage solar production data for energy yield monitoring automation, handle battery storage status for home energy management automation, access consumption monitoring for grid import/export automation, retrieve system health for installation alerting automation, manage fleet reporting for solar portfolio analytics automation, handle production forecast for weather-adjusted yield automation, access tariff optimization for time-of-use scheduling automation, retrieve system configuration for installer management automation, manage performance alerts for maintenance dispatch automation, and integrate Enphase with home automation, energy storage, and grid management platforms for end-to-end solar energy automation.

Open-source drag-and-drop UI for building LLM applications and agent workflows. Flowise lets you visually construct LangChain and LlamaIndex pipelines — connecting nodes (LLMs, vector stores, retrievers, tools, memory) into chatflows and agentflows without writing code. Every built workflow exposes a REST API endpoint for programmatic access. Used for building RAG chatbots, agent workflows, and LLM pipelines visually.

Open-source AI testing and quality assurance platform for LLMs and ML models. Giskard provides automated vulnerability scanning for LLMs (prompt injection, hallucination, stereotypes, toxicity), RAG pipeline evaluation, and model testing with a Python SDK. REST API and Python client for running scans, generating adversarial test cases, and retrieving vulnerability reports. Giskard Hub is the managed collaboration platform.

Modern authentication and authorization platform offering OAuth2/OIDC, SSO, MFA, and user management via a hosted auth service with REST APIs and first-class SDK support.

Indie-focused game backend BaaS providing player authentication, leaderboards, progression, inventory, economy, and asset storage via a straightforward REST API.

Multi-agent framework that simulates a software engineering team — product manager, architect, engineer, QA. MetaGPT takes a one-line requirement and generates PRD, system design, code, tests, and documentation using coordinated LLM agents with defined roles. No REST API — runs as Python framework. Strong for autonomous software generation and multi-agent research. MIT licensed.
