Pricing
FreemiumFactory offers five tiers. Pro is $20/month for individuals, including desktop, CLI, and SDK access, cloud and local background agents, and a billing/usage dashboard. Plus is $100/month with roughly 5x the usage of Pro plus Droid Computers, Factory-managed cloud computers for remote Droids. Max is $200/month with roughly 10x the usage of Pro and early access to new features. Business is custom-priced for growing teams up to 150 seats, adding custom usage limits, dedicated onboarding, SSO, SAML/SCIM provisioning, Zero Data Retention, audit logging, and basic admin controls. Enterprise is custom-priced with unlimited team members, dedicated compute with a partitioned inference pool, an Agent-readiness Improvement Program, on-premise deployment, sub-organizations, full admin controls, customer-managed encryption keys, data residency, and a dedicated account manager with SLA-backed support.
FreeAider itself is completely free and open source under the Apache 2.0 license, with no subscription, tiers, or usage limits imposed by the project. Costs come entirely from the LLM provider a developer chooses to connect: for example, Anthropic, OpenAI, or DeepSeek API usage is billed directly by that provider at its own per-token rates, or developers can run local models through Ollama at no cost at all. Because there is no Aider-specific markup or platform fee, effective cost is determined by model choice and usage volume rather than by Aider itself.

Factory Pros & Cons
Pros
- Droids execute full tasks (editing files, running commands, opening PRs) rather than just suggesting code
- Genuinely model-agnostic and interface-agnostic, avoiding lock-in to one IDE or LLM provider
- #1 ranking on Terminal Bench, a widely used industry benchmark for coding agents
- Sovereign deployment options including on-premise and air-gapped environments for regulated industries
- Strong enterprise traction with named customers like Nvidia, Adobe, EY, and Morgan Stanley
Cons
- Best suited to teams with a real backlog of well-specified work and enough review capacity to absorb the resulting pull requests
- Not ideal for solo developers wanting lightweight autocomplete, or teams whose work is mostly ambiguous product design
- Business and Enterprise pricing is fully custom, requiring a sales conversation rather than transparent self-serve rates
- Heavy multi-agent or long-context usage can run up consumption costs quickly on usage-based components
- As a younger platform (founded 2023), its track record is shorter than more established coding agent competitors
Aider Pros & Cons
Pros
- Completely free and open source, with no platform markup on top of LLM provider API costs
- Deep git-native workflow makes every AI change individually reviewable, diffable, and reversible
- Model-agnostic support for 100+ LLM providers, including local models, avoids vendor lock-in
- Efficient repo mapping keeps large codebases manageable without dumping entire files into context
- Transparent, actively maintained public leaderboard helps developers pick the best-performing model for real coding tasks
Cons
- Terminal-only interface has a learning curve for developers used to GUI-based tools like Cursor or Copilot
- No bundled AI access; users must bring their own API keys and manage separate billing with LLM providers
- Deliberately not a fully autonomous agent, staying one step behind tools like Devin that run unsupervised for longer stretches
- No official enterprise support tier or SLA, since the project is community-maintained open source
