## 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

## Solarch

Solarch inverts the usual AI coding flow. Rather than generating code and hoping the architecture catches up, it produces architecture first: you draw your backend as a node/edge graph using 21 node types across 8 families and 16 typed relationships, and a default-deny Rules Engine validates every connection as you draw it. Concepts like a controller reaching directly into a database table are simply not drawable, so structural mistakes are caught at design time instead of in code review.

Once a graph is validated, a hybrid code engine takes over. Stage one is a deterministic compiler that turns nodes and edges into a skeleton — DTOs, entities, constructor injection — using no model tokens at all. Stage two applies AI surgically to fill only the empty function bodies, so the algorithmic logic stays yours and roughly 80% of a project ships as boilerplate. Graphs are organised fractally: each node lives in one home tab and other tabs import it as a ghost reference rather than making a copy, which keeps large systems coherent, and semantic zoom lets you move from macro modules down to micro-graphs.

The architecture then travels with you. A VS Code extension shows a revision timeline and live drift findings in the Problems panel; the CLI provides drift guard, two-way sync and deterministic NestJS code generation and can block merges that break the architecture in CI; and an MCP server supplies Claude, Cursor and other agents with the real graph plus the rules, so every write only commits when the edges pass. Type safety runs from the database schema through the API contract to the typed client, and changing a column stops the frontend compiling until it is reconciled.

**Pricing & Plans:** A free-forever tier covers two projects, the live canvas, the AI architect and default-deny validation with no credit card. Paid tiers run Draw at $5/month for unlimited sketchpad use, Build at $20/month for extended AI usage plus code generation and ZIP export, Code at $100/month for full codebase generation, and Team at $30 per seat for shared projects. A 7-day trial applies to paid plans, and Enterprise adds self-hosting, SSO, audit logs, a custom rules matrix and dedicated support.

- **Live node/edge canvas:** Model the whole backend — controllers, services, repositories, tables, DTOs and queues — on one surface with 16 semantic edge types across 8 families.
- **Default-deny rules engine:** An illegal connection such as wiring a controller straight to a table is rejected the instant you draw it, based on 7 anti-patterns and 3 conditional checks.
- **Hybrid code engine:** Stage one compiles the graph deterministically into skeletons with zero tokens; stage two uses surgical AI to fill only the empty function bodies.
- **GraphRAG grounding:** A LangGraph-powered architect grounds every plan in a vector-indexed library of canonical patterns instead of autocompleting from scratch.
- **Developer tooling:** VS Code extension, CLI with drift guard and two-way sync, and an MCP server so AI agents work against the real, rule-checked architecture.

**Strengths:** Architecture is validated before any code is written, so drift is structurally prevented; Deterministic stage-one generation keeps token costs low; Writes commit only when the graph passes the rules, not just when the model feels confident; Same diff engine across editor, CLI and AI agent

**Limitations:** Requires willingness to model the system as a graph before coding; Deterministic generation is currently deepest for NestJS-style backends; The full codebase tier is a serious monthly commitment for individuals
