What is Appwrite?
Appwrite hardens auth and broadens its framework and runtime surface as a Firebase alternative.
Appwrite is an open-source backend-as-a-service competing with Firebase and Supabase across auth, functions, storage, realtime, and hosted Sites. The recent cadence is broad and infrastructure-heavy: auth hardening (password strength, email policies), new realtime primitives (Presences), storage speedups, more build runtimes (Bun, Deno, Dart, Flutter), and a first-class React library. It also tightened free-tier economics by deleting long-paused free projects.
What is Stirling-PDF?
Stirling-PDF is hardening its desktop app while commercializing a metered, AI-billed SaaS.
Stirling-PDF is shipping fast on two fronts. The open-source desktop app keeps hardening, with hardware-token signing, multi-window, memory-efficient merge/split via JPDFium, and broad package distribution, while a parallel SaaS effort adds pay-as-you-go billing for AI and automation, MCP support, and org-wide policy enforcement. A v2 UI rework, files on the left and tools on the right, runs through recent releases.

Appwrite
6.3DEVOPS
Appwrite hardens auth and broadens its framework and runtime surface as a Firebase alternative.
◆ Current state
Appwrite is an open-source backend-as-a-service competing with Firebase and Supabase across auth, functions, storage, realtime, and hosted Sites. The recent cadence is broad and infrastructure-heavy: auth hardening (password strength, email policies), new realtime primitives (Presences), storage speedups, more build runtimes (Bun, Deno, Dart, Flutter), and a first-class React library. It also tightened free-tier economics by deleting long-paused free projects.
◆ Where it's heading
The platform is investing on two fronts at once — developer experience (React hooks, monorepo-aware Git build triggers, a Claude Code plugin) and backend breadth (presence, auth policies, faster uploads). The pattern is filling parity gaps with Firebase and Supabase while courting framework-native and agent-assisted workflows. Free-tier cleanup suggests attention to cloud cost discipline alongside feature growth.
◆ Prediction
Expect the React library to grow past auth into data and realtime hooks, and continued runtime and framework additions for Sites and Functions.
Stirling-PDF
6.3DEVOPS
Stirling-PDF is hardening its desktop app while commercializing a metered, AI-billed SaaS.
◆ Current state
Stirling-PDF is shipping fast on two fronts. The open-source desktop app keeps hardening, with hardware-token signing, multi-window, memory-efficient merge/split via JPDFium, and broad package distribution, while a parallel SaaS effort adds pay-as-you-go billing for AI and automation, MCP support, and org-wide policy enforcement. A v2 UI rework, files on the left and tools on the right, runs through recent releases.
◆ Where it's heading
The project is splitting into a free self-hosted tool and a commercial SaaS with metered AI and automation. Backend work, cluster backplane, S3 storage, pay-as-you-go billing primitives, and policy enforcement on upload and export, is groundwork for running Stirling as a multi-tenant service. On the desktop side the focus is enterprise-grade signing and distribution. Release cadence is high, roughly weekly.
◆ Prediction
Expect the SaaS pay-as-you-go and MCP features to move toward general availability and the desktop app to keep adding enterprise signing and management features; the in-progress file-management UI is the likely next thing to stabilize.
