How to Switch from LlamaIndex to LangTool
The migration, step by step
- 1Prepare
Audit how you actually use it
List the LlamaIndex features your team touches weekly. Most teams use 20% of features for 80% of the work — those are the only ones the free alternative must cover.
- 2Prepare
Export your data first
Before anything else, export everything from LlamaIndex. Keep the export in its original format plus any open standard offered (CSV, JSON, SVG, Markdown). Do not cancel yet.
- 3Pilot
Set up the free alternative
Install or open LangTool and recreate one small, real project from scratch — not a toy file. This surfaces gaps while switching is still cheap.
- 4Pilot
Run a two-week pilot in parallel
Do live work in LangTool while keeping LlamaIndex read-only. Note every friction point; most disappear after the first week as muscle memory adjusts.
- 5Migrate
Migrate your assets
Move your exported files into LangTool. Where direct import is unsupported, use the open-standard export (CSV/SVG/Markdown) or a one-time conversion — then keep the originals archived.
- 6Cut the cost
Cut the subscription
Cancel LlamaIndex at the end of the billing cycle (avoid losing access mid-cycle). Check the cancellation date against your renewal to dodge the next price increase.
