One place. All your software.
AI runs it. You decide.
Every project in one chat. AI writes the code, runs your tests, ships the preview. Your team reviews. You approve — from anywhere.
Chat + live preview
Agent edits, you watch the dev server reload in real time.
From idea to live software
in three steps.
Describe it in chat
Type what you want in plain English. Agent reads your codebase, database schema, and recent conversation — no specs to write, no tickets required.
Agent ships in your workspace
Claude (or your AI of choice) runs in a private workspace with database + live preview. You watch it work in real time.
Approve, ship live
Like the result? Tarrs ships the change to your repo and updates the preview. Don't like it? Continue in chat — agent iterates instantly.
Built for founders who ship —
solo, studio, or anywhere between.
Whether it’s your first MVP or your tenth portfolio company, Tarrs is the operating system that keeps every project moving.
Chat is the workflow
One conversation per project. CEO submits, engineer reviews, tester approves. @-reference any ticket. The agent uses the full thread as context.
Real dev sandbox per project
Each project gets its own Fargate task with EFS persistence + Postgres sidecar + dev server. Customer's app, hosted by us, previewed live in the chat.
Bring your own AI
Plug in your Anthropic / OpenAI / Gemini API key, or OAuth your Claude Pro/Max subscription. Tarrs never marks up tokens — you pay providers direct.
GitHub-native, no lock-in
Code stays in your repo. Tarrs commits via your GitHub App. Tomorrow you stop using us — your code is exactly where you left it.
Tarrs vs the prototype tools.
Replit, Lovable, Base44, Bolt.new ship the demo. Tarrs ships the product — multi-env, multi-service, BYO data, GitHub-native, no lock-in.
| Dimension | Tarrs | Replit | Lovable | base44 | Bolt.new |
|---|---|---|---|---|---|
| Category | AI app factory — real products | Cloud IDE + AI assistant | AI prototype generator | AI prototype generator (locked stack) | AI prototype generator (in-browser) |
| Target user | Founders, PMs, small dev teams, agencies | Developers + learners | Non-technical / designers | Non-technical founders | Developers quick-trying |
| Where your data lives | Your call — platform / your Supabase / your own DB | Replit's Neon | Pushes Supabase | Locked to theirs | No real DB |
| Where code deploys | Your call — Tarrs / Vercel / your AWS / any GitHub host | Replit Deployments | Pushes Vercel | Locked to theirs | Export to Netlify / Vercel |
| Multi-env (dev / staging / live) | All three built-in | Single env | |||
| Multi-service per project | Native | One repl, one service | |||
| Backend logic | Node / Python / Go / anything | Anything | Edge Functions only | Limited | WebContainer limits |
| Data + cache + file storage | All included | DB only | Through Supabase | Built-in | |
| Multi-member collaboration | Multi-member + per-member AI sessions | Real-time co-editing | Team, but siloed | ||
| Permission tiers | owner / dev / chat / viewer | ||||
| Code review flow | AI changes ship as PRs | ||||
| GitHub integration | Native | Sync | Shallow | Export only | |
| AI provider | BYOK (Anthropic / OpenAI / Gemini) | Platform's own | Platform's own | Platform's own | Platform's own |
| Portability (no lock-in) | Standard Postgres + GitHub — take it and go | Supabase-locked | |||

Pay for the sandbox.
Bring your own AI.
A typical project runs ~$30–40/month. A small team with ~4 projects, ~$120–160/month total.
Pure pay-as-you-go — no subscription, no per-seat fees. You pay for the hours a sandbox is actually running, plus a small data-retention fee that keeps it parked & instantly resumable. Your AI tokens go on your own key — never marked up by Tarrs.
The detail · compute billed by the second while running — Start $0.11/hr (1 vCPU/2 GB) · Plus $0.22/hr (2/4) · Pro $0.26/hr (2/8) · Max $0.50/hr (4/16). Spot ~25% cheaper. Paused projects pay a small data-retention fee (a fraction of the rate). Storage & bandwidth metered.
Stop being the bottleneck.
