A developer reports that Windsurf’s free in-IDE model SWE-1.5 enabled shipping a GPS quest game MVP with a Node.js/Express + PostgreSQL backend in a single weekend, detailed here: Windsurf's SWE-1.5 is AMAZING1. SWE-1.5 handled most coding, with a few prompts offloaded to Claude Opus and gpt-5.2 and OpenRouter for quest generation—showing low-cost LLMs can accelerate full‑stack delivery.
-
Firsthand build report with stack, scope, and time-to-MVP; highlights SWE-1.5’s speed/conciseness, limited use of Claude Opus/gpt-5.2, and OpenRouter API for content. ↩
Demonstrates that a free, lightweight model inside the IDE can materially compress backend delivery timelines.
Validates a pragmatic multi-model workflow (cheap model for most code, premium models for tricky fixes).
-
terminal
Use SWE-1.5 in Windsurf to scaffold a Node/Express + Postgres service (CRUD, migrations, integration tests) and compare review defects versus your current workflow.
-
terminal
Evaluate a multi-model fallback (SWE-1.5 primary, premium model for complex bugs) and track latency, cost, and quality deltas.
Legacy codebase integration strategies...
- 01.
Trial SWE-1.5 on a small service behind feature flags with strict CI (linters, SQL migration review, security checks) to assess fit and drift from standards.
- 02.
Check generated code for adherence to your logging/tracing, secrets handling, and DB access patterns before broader rollout.
Fresh architecture paradigms...
- 01.
Adopt a modular feature-oriented structure early and have SWE-1.5 generate service templates, tests, and DB schemas from the same spec.
- 02.
Use OpenRouter or similar only for non-critical content generation while keeping core business logic under tighter review gates.
