## Convex

Convex takes the usual backend checklist — database, queries and mutations, background jobs, storage, search, auth — and runs it as one cohesive TypeScript programming model. Data is reactive by default: when a mutation changes a document, every subscribed client updates without you writing polling or subscription code. Because functions are serverless and transactional, concurrency problems that normally require careful locking are handled by the platform.

A big part of the current pitch is agentic coding. Convex ships AI-friendly guidelines and plugins for editors such as Claude Code and Codex, along with official Agent, Workflow and Workpool components, so an assistant can scaffold schema, functions and integrations that match Convex conventions. The AI Gateway lets you route requests to many models through a single credential instead of managing a dozen provider keys.

Pricing is usage based with a generous free tier. The Starter option is pay-as-you-go, Professional runs about $25 per developer per month with higher included resources, and Business/Enterprise plans start around a $2,500 monthly minimum with SSO, SLAs and dedicated deployments. Data region selection, SOC 2 Type 2 and HIPAA support are available on higher tiers.

**Pricing & Plans:** Free/Starter tier with pay-as-you-go usage pricing; Professional around $25 per developer/month; Business & Enterprise with a ~$2,500 monthly minimum offering SSO, SLAs and dedicated deploys.

- **Reactive database:** Document store with ACID transactions that pushes live updates to subscribed clients automatically, no manual invalidation needed.
- **All-TypeScript backend:** Schema, queries, mutations, actions and HTTP endpoints are written in TypeScript with end-to-end type safety from client to database.
- **Convex Components:** Open-source modular building blocks such as Agent, Workflow, Workpool, Stripe, Resend and Twilio that drop into your app.
- **AI Gateway:** Call major language models through one unified API and billing path instead of managing separate provider credentials.
- **Built-in search, storage and auth:** Vector search, full-text search, file storage and 80+ OAuth authentication providers come standard.

**Strengths:** Reactive data sync is native, removing a whole class of caching and polling code; End-to-end TypeScript type safety catches mistakes before deployment; Rich component library covering agents, workflows, payments and messaging; Clear usage-based pricing with a real free tier and transparent unit rates

**Limitations:** Vendor lock-in: application logic is built around Convex-specific functions and conventions; Costs scale with compute and I/O usage, which can surprise high-traffic apps; Self-hosting is possible but less mature than fully managed deployments

## Postgres Sandbox

Postgres Sandbox, available at postgres.new, takes an idea that sounds unlikely and makes it work: a real PostgreSQL database running entirely inside your browser. It is built on PGlite, a full build of PostgreSQL compiled to WebAssembly, so there is nothing to install and no server to configure. The moment you start writing SQL, a new database is created for you automatically.

Around that core it adds a set of tools for getting things done quickly. An AI assistant helps turn natural-language requests into SQL and to reason about queries, which is valuable when you are sketching a schema or exploring unfamiliar data. You can import CSV files and query them immediately, generate charts from results, and draw ER diagrams to see how tables relate.

Because the engine is genuine Postgres, the SQL semantics match what you would get on a real server, which makes the sandbox a natural place to prototype schemas, test a tricky query, teach SQL, or experiment with semantic search and RAG-style retrieval. It is best understood as a fast, disposable workspace rather than persistent production infrastructure — data lives in the browser rather than on a managed database.

**Pricing & Plans:** Free. Postgres Sandbox runs in the browser at no cost — there is no install, no account requirement mentioned and no paid tier advertised. Just open the page and a PostgreSQL database is created as you start writing SQL.

- **Instant in-browser Postgres:** A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration.
- **AI SQL generation:** An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work.
- **CSV import:** Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration.
- **Charts and ER diagrams:** Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace.
- **Semantic search and RAG:** Explore RAG and semantic-search style workflows against your data, using the sandbox to prototype AI data features.
- **Real Postgres semantics:** Because it is real PostgreSQL, SQL you write here behaves like SQL you write on a server, so results transfer.

**Strengths:** Runs real PostgreSQL with no install or server setup; AI assistance lowers the learning curve for SQL; CSV import, charts, ER diagrams and semantic search in one place; Genuinely free and instant to try in the browser

**Limitations:** Data lives in the browser session, so it is not a persistent production database; Persistent storage depends on browser/IndexedDB and can be cleared; Not a substitute for a managed Postgres server for real applications; AI-generated SQL should still be reviewed before running
